E911 For Enterprise VoIP

The move from switched circuit to packet switched telephony has created some unintended consequences. One of these is emergency calling to 911. We take the 911 system for granted. When disaster strikes, just punch in those three little numbers and help will be on the way. Well, that’s the way it’s supposed to work.

Now consider this. There’s a fire in the maintenance closet down the hall and it’s getting out of control. You pick up your handset and dial 911. You reach the emergency operator and report the fire, then run out of the building and across the street. An hour later, the facility has burned to the ground and no fire trucks have shown up. How could this happen?

The fire trucks did show up within 5 minutes of your call. Unfortunately, they went to your main office in Phoenix. You just called from the satellite office in Indianapolis. Oops! Something is not set up properly on your VoIP phone system.

Such a problem would never arise on an analog landline phone. Why? Because the phone wire is in the ground at it always goes the same place. That’s why they call it a landline. VoIP, however, is a network service. As long as a SIP phone can connect to the network, it can make a call. It makes no difference where that connection takes place. Networks that encompass multiple locations need special consideration when they are converged for voice and data. The same technology that makes it easy to move phones around also makes it easy to lose track of just where they are plugged-in. This is especially true if any of your phones connect via the Internet.

Make no mistake about it. VoIP technologies, including Hosted PBX and Unified Communications, offer enormous benefits in cost reduction and employee productivity improvement. Like all new technology, the more cutting edge the solution, the trickier it is to get it right. You want to be working with a top-tier service provider who understands the legal requirements for issues such as E911 and has processes in-place to ensure that your system is set up accurately.

If you are considering an upgrade to your business phone system, get recommendations, options and pricing on competing telephony solutions. Be sure you understand how they ensure accurate E911 call routing.

Cloud Hosting Providers For Converged Networks

Cloud computing services are growing geometrically. If you haven’t gotten on-board yet, it’s probably because you aren’t convinced of the cost savings, security or the ability of the cloud to cover all bases for your IT needs. That picture is changing rapidly. Let’s take a snapshot of what’s available now for SMB users.

When we think of cloud computing, the picture that comes to mind is one of a giant brain in the sky that runs operations for hundreds or thousands of companies. That’s the approach that gets all the press, but it’s far from the entirety of the market. Indeed, there are many other providers out there who can deliver the virtual services you need on a less grand scale. You may not be able to get everything from one service provider, but the building blocks are out there to handle your voice and data needs.

That’s important, because enterprise VoIP solutions are driving a trend toward converged networks. If you only consider moving traditional data center servers to the cloud, you’ll be missing a big piece of the puzzle. The other trend that’s important is fixed mobile convergence that integrates cell phones into your telecom infrastructure. Mobility can be the link that makes or breaks your productivity in the future.

The foundation of cloud computing is cloud hosting that incorporates Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Cloud infrastructure is virtualization on steroids. IT departments have found that virtualizing servers ups the efficiency of the physical server hardware. What cloud computing does is greatly expand the virtualization to include huge racks of high performance servers plus storage and bandwidth. It differs from the virtualization that you would do yourself or the virtual servers you’d rent from a colocation center in that it is sold incrementally on-demand. You pay by the minute, by the hour or by the number of CPU cycles used.

Another characteristic of cloud hosting is that it is highly elastic or scalable. If you start to run out of capacity, you simply order up more virtual servers. The cloud operating system takes care of how these resources work in concert to provide the capacity you need. At no point do you have to purchase, install or maintain any equipment. The cloud service provider takes care of this with a 24/7 technical staff.

There are actually three types of clouds to choose from. The one that first comes to mind is the public cloud that serves many users simultaneously. You gain access via a private line or dedicated Internet service. Companies that have highly sensitive applications, unique requirements or simply want more control go with a private cloud. That is a similar infrastructure to the public cloud but on a scale suitable for one company. The hybrid cloud is a combination of the two. Public facing or non-critical applications run on the public cloud, while a separate private cloud handles very sensitive applications.

While cloud computing is thought of a data processing service, there is also a voice cloud known as cloud communications or hosted PBX. In this case, the computing resources are specific to telephony needs and the connectivity is by SIP trunk from your location and to the public switched telephone network from the provider. You no longer need a PBX phone system in-house or any telephone trunk lines. What you have is SIP telephones connected to your network and a converged SIP trunk from your business location or locations to the service provider. Some hosted PBX systems integrate cell phones into the system so that you have the same capabilities while mobile as at your desk.

Some of the cloud services you can readily get include cloud hosting, hosted PBX, unified communications, enterprise cloud security, private/public clouds, cloud storage, hosted Exchange, SharePoint, disaster recovery, anti-spam and anti-virus, hosted firewalls, and dedicated cloud access connections.

Are you feeling that you may be missing out on productivity improvements, cost savings, agility of scaling your business, or advanced features available in the cloud? This would be a good time to explore options with multiple cloud hosting providers. You can start small and grow or make a step-change relocation to the cloud, depending on what works best for your company.

SIP over MPLS for Enterprise VoIP

SIP Trunking is widely popular for smaller businesses who can save on their monthly telecom bill by getting both their telephone and Internet broadband services on a single integrated line. SIP Trunking is also a cost saver for large corporate headquarters or call centers that need many outside phone lines and already have converged voice and data LANs. But what about the organization with multiple locations?

The answer may well be SIP over MPLS. You may already have an MPLS network in place for sharing data files between branch offices and headquarters. Cost tradeoffs almost always give the advantage to an MPLS network over a suite of point to point data lines of equivalent bandwidth. With MPLS, you only need a last mile connection to each of your locations. As the name implies, these are point to point pipes measuring just thousands of feet to the nearest central office. The major distance spans are handled by the fiber optic core of the MPLS network.

There are also security advantages with MPLS versus IP networking, such as the Internet. MPLS uses proprietary labels to direct traffic, not the IP header information that is often the target of malicious activity. The network is privately operated and not accessible by the general public. You need to be a contracted customer with defined locations and connections between them that are managed by the network operator.

What you may not realize is that MPLS networks can handle voice traffic as well as data. The name MPLS actually stands for Multi-Protocol Label Switching. The network can handle nearly any protocol and is perfect for packet switched services of all types. For larger organizations, MPLS provides the WAN connections you need to link a few or many converged voice and data networks.

Do you currently have data connections between your sites but stand-alone analog or PRI telephone lines at each? That works, but you are probably paying toll charges to call between offices. There’s no economy of scale if each facility is relatively small and in a different city or state than the others. By consolidating your telephony, data lines and perhaps broadband connectivity with a single provider you can likely realize a considerable cost savings while maintaining call quality and network speed.

The MPLS labels or tags do their magic by not only specifying packet destinations, but also class of service. This keeps data file transfers from damaging the much more fragile real-time demands of voice and video. If you have company wide VoIP now and conversations get distorted or calls drop when the network gets congested, traffic engineering is what you need. MPLS networks are engineered with committed rates for your services, as well as those of other network customers. That ensures that you have the bandwidth you purchase regardless of what anyone else is doing. Contrast that commitment with the best-effort information services, such as the Internet, where performance is all over the map.

With SIP over MPLS, your telephone calls within the company stay on-net and off the public switched telephone network. You don’t pay toll charges for office calls that stay on your network regardless of whether they are from desks twenty feet apart or branch offices thousands of miles apart. It’s even possible to include international locations on the same MPLS network to truly integrate your company communications. When calls go off-net to outside landlines or mobile phones, those terminations are handled by your SIP Trunking service provider. Since the network is converged, there is no need for a separate telephone network and your support needs may also be reduced.

Does your organization have multiple locations that could be more efficiently run by a voice and data MPLS network? Get pricing for MPLS Network Services quickly and easily to compare with your current bills.

PRI Phone Line Connections

Traditional analog business phone lines are useful in very small retail and office locations and any business where just a few outside lines are all you need. Once you accumulate more than half a dozen, it’s time to look at a telephone trunk like option like ISDN PRI.

ISDN PRI stands for Integrated Services Digital Network Primary Rate Interface. Now you know why they abbreviate it. ISDN is a set of standards for how to transmit phone calls digitally on ordinary telephone wire. PRI is the larger of two major options. The other, BRI or Basic Rate Interface, provides two telephone lines, one telephone and one 64 Kbps data line, or a 128 Kbps data line. It’s mostly used for low speed data connections or to transmit high quality audio for broadcast and production.

PRI is the business telephone trunk service that is highly popular for use with PBX phone systems. PRI is transmitted on a T1 line using two twisted copper pair. Chances are you are already familiar with T1 lines for dedicated Internet access at 1.5 Mbps. ISDN PRI, also called T1 PRI, uses the same T1 line technology. In fact, T1 lines were originally designed to transport telephone conversations in bulk between telco switching offices.

What do you get with ISDN PRI service? A single trunk can support up to 23 separate phone conversations, each in its own time division multiplexed channel. Think of these as the equivalent of 23 outside lines. Each line can be set up for local, long distance, incoming only, outgoing only, toll free or some combination. There are actually 24 channels on the T1 line. The last one is reserved for switching signals to support the other 23 plus data such as Caller ID.

ISDN PRI lines almost always plug into an interface card made especially for this purpose. There’s at least one in most PBX phone systems. Some have four or more ISDN PRI connectors so that you can add dozens of outside lines if your operation is large enough to need them. Call centers are big users of ISDN PRI, as are large business offices.

PRI pricing has been getting better over the years, following the declining cost of T1 lines. A few years ago, PRI became more cost effective when you exceeded 10 or 12 outside phone lines. Today, that number is more like 6 or 10 lines, depending on where you are located.

Other than analog phone lines, the direct competitor to ISDN PRI is SIP Trunking. PRI is a traditional telephone technology that connects your PBX system to the public switched telephone network. SIP Trunking is a packet based technology originally designed to support enterprise VoIP telephone systems. SIP Trunks connect directly to converged networks for enterprise VoIP support and can supply both phone and Internet service for smaller companies. SIP Trunks can also be ordered with analog, IP or PRI handoffs to connect to any PBX telephone system.

What type of telephone trunk line is best for your particular situation? Consider the interfaces you have available and get competitive prices and availability for business telephone lines and trunks to make a good decision.

SIP Trunking Providers Want Your Bandwidth

The telephone industry is changing. Not long ago, the standard setup for most companies was an in-house PBX system managing dozens, hundreds or thousands of phones. For outside calls, the most cost effective approach has been to bring in ISDN PRI trunk lines with 23 local and/or long distance lines each. Even small companies chose key telephone systems that can handle two to six outside lines. Those setups are changing fast.

There are two strong trends in the industry right now. One is cloud based hosted PBX telephone and the other is SIP trunking. They work perfectly together, but you can also have SIP trunking without cloud services.

A telephone trunk is a number of telephone lines all bundled together. This can be a wire bundle, such as a multi-line copper cable. It can also be an electrical bundle on a single line. ISDN PRI trunks, for instance, bundle 23 separate phone lines plus Caller ID and switching on a single T1 line. A SIP trunk is a telephone trunk line designed specifically to work with IP phones in VoIP telephone systems. SIP or Session Initiation Protocol is the switching technology used in VoIP in lieu of SS7, which is used in traditional switched circuit telephony.

So, why are SIP trunks such a hot item right now? It’s because a SIP trunk can be connected directly to your network or IP PBX to bring in multiple lines from your VoIP carrier. On a converged local area network, you are already running SIP. Why go to the trouble to converting to another protocol just to gain access to the public telephone network?

SIP trunks are also how you connect to a hosted PBX system as a cloud service. Companies are rapidly discovering that the per-seat cost of a cloud based telephone service is less than they pay now when you count the personnel, operating and maintenance costs of an in-house phone system. With hosted PBX, you no longer have to invest in new hardware every few years and your system is always being maintained and upgraded by the service provider.

It stands to reason that SIP trunking providers want your telephone business, but why do they want your bandwidth?

The reason that your carrier wants to provide you with both telephone lines and Internet bandwidth is so they can guarantee the quality of your phone calls. With traditional telephony, the telephone and computer networks are kept completely separate and cannot possibly interfere with each other. One of the cost saving advantages of enterprise VoIP solutions is that they use the corporate data network for everything. To make that work, you need to prioritize voice packets so that your phone conversations don’t distort or break up no matter what the computers are doing.

When your SIP trunking provider delivers both telephone and Internet service on your trunk line, they prioritize packets using CoS or Class of Service tags. These tags tell all equipment that recognizes them how to handle different types of traffic to ensure service quality. Not all bandwidth providers do this, so if you mix various line services you can wind up undoing your carefully engineered network quality.

There’s also a cost advantage, especially for small businesses who get both telephone and broadband on one line instead of two. You don’t even need IP phones to take advantage of this service. The provider will install an Integrated Access Device (IAD) that can connect to conventional analog phones and your broadband router.

Now that you know why SIP Trunking providers want your bandwidth, why not find out what sort of deal they’ll make to get it? Request competitive quotes for telephone trunking, dedicated Internet access and cloud hosted PBX services now.

Cost Performance Advantage of Ethernet over Copper

Most businesses have some type of bandwidth connections for credit card verification, email, online searches, location to location data transfers, procurement, research and a host of other needs. These connections run the gamut from information services such as DSL, Cable, satellite and wireless, to telecom services like T1, DS3, OC3 and Ethernet over Fiber. The new player, with cost vs performance advantages you should consider, is Ethernet over Copper.

Why Ethernet over Copper? First of all, this is a protocol that most closely matches what is running on nearly all networks today. That is, Ethernet. Most other services were designed back in day when voice was king and the public switched telephone network dominated worldwide communications. That’s no longer the case. The world has not only transformed from analog to digital, but has also moved from telephone conversations to email, texting, video downloads and streaming, search and Websites.

Voice landlines are on the decline. While users increasingly choose cellular calls, businesses are transforming desk phones to enterprise VoIP and carriers are quietly converting their core networks from circuit switched to packet switched architectures. Even the next generation of smartphones may choose VoIP over LTE rather than continue the proprietary GSM and CDMA voice channels. All of this means an increasing stampede toward Ethernet as the universal networking protocol.

Using Ethernet instead of some other telecom protocol improves network efficiency since no conversions are required and interfaces are simpler. It also enables Ethernet strategies such as layer 2 switching vs layer 3 routing to connect geographically separate LANs on one large bridged network. This strategy works not only in the metro area networks, but also nationwide through metro networks and worldwide through Ethernet exchanges. We’re not far from the day when Ethernet will the common denominator and all networks will be IP over whatever’s at the core.

Now you know why it makes sense to run Ethernet rather than some other protocol, such as T-carrier or SONET. But why Ethernet over Copper?

The beauty of Ethernet over Copper (EoC) is that it makes good use of existing infrastructure to avoid construction costs. Business phone lines and T1 line connect using twisted pair copper wire bundles that are routinely installed for every business. Ethernet over Copper uses the very same installed copper. How this works is that the EoC provider installs the EoC equipment at the central office and compatible customer premises equipment at your location. In between, they simply lease the unpowered or “dry” copper pair that is already in place. In most cases two or more pair are utilized.

There’s a correlation between how many copper pair are connected and the speed of your line service. The more pair, from 2 to 8 typically, the higher the bandwidth. The modulation efficiency of this equipment yields higher bandwidths than you get from T1 lines and typical DSL or satellite links. A very popular entry level EoC service is 2 or 3 Mbps. That’s easily increased to 10, 15 or 20 Mbps in most locations. Even 50 and 100 Mbps over copper is not unheard of.

The one tradeoff is speed for distance. The closer you are to the telco office where your copper terminates, the higher that bandwidth you can achieve. In unusual cases, your location is extended more than 2 or 3 miles and EoC service won’t work. In those cases, you may still be able to get Ethernet over DS1 using the same transmission technology as T1 lines.

It’s true that you can get higher download bandwidths using Cable broadband or some wireless services. However, upload bandwidth on these services tends to be maybe a tenth the download speed. Ethernet is symmetrical, meaning that upload and download speeds are the same. This is important if you upload large files or operate on-premises servers.

Beyond technology, pricing is a big advantage for EoC vs T1 and even fiber optic services. Remember that Ethernet over Copper can deliver large bandwidths that delay or even avoid the expensive construction of fiber optic connections. EoC typically delivers twice the bandwidth of T1 for about the same price. At higher bandwidth levels, the cost savings is even more striking.

Could your business benefit from EoC service? Find out by checking prices and availability of Ethernet over Copper bandwidth for your business locations. Sorry, no residential service available.

IP Exchange - The Final Piece For VoIP

It’s no secret that the world’s telephone communications are on a fast path from circuit switched to packet switched networks. Large businesses have embraced enterprise VoIP as a way to improve productivity, reduce costs and future-proof their in-house telephone systems. Small and medium businesses are taking a close look at SIP trunking as a way to get high quality telephone and broadband service as a bundle. Consumers have taken matters into their own hands by moving to Cable broadband-telephone bundles or third party VoIP services. Yet, the PSTN persists.

What’s holding up this house of cards? Right now every VoIP system and service is an island unto itself. You’ll more often than not find that on-net calls for any particular VoIP service are free. On-net means on that particular service, unrelated to location. This is because the provider owns the network and doesn’t have to pay anyone else to handle the traffic. They are making money through the monthly fee they charge their customers for the VoIP service itself.

The same is true for large companies with their own enterprise VoIP systems. One of the big cost advantages of VoIP is that you can eliminate the separate telephone network and use your data network to transport voice, data and video. Another savings comes from keeping your voice traffic on your own network, not just within an office but also between locations. Avoid the public telephone network and you avoid the per minute charges to use it.

Therein lies the rub. The only common link between all telephones on Earth is the PSTN or Public Switched Telephone Network. Its legacy is based on switching analog phone circuits to make the phone to phone connections. Long haul circuits have long since gone digital, but a very special type of digital. The phone conversations are digitized according to an international standard, G.711, and packed into rigidly synchronized channels called DS0s. A DS0 is 64 Kbps and is the same whether being transported on a T1 or PRI trunk line right on up to a fiber optic OC-768 cable. Cellular phones have their own network standards, but are designed to interface with the PSTN to hand-off traffic.

The heart of the PSTN is both its technical specs for connecting analog and digital conversations and its switching systems called SS7. Nowadays the switching signals have their own separate paths between switching offices in a hierarchy consisting of local central offices and tandem offices that connect the local offices into one large universal network. If you want to connect with any phone on the PSTN, you need to send the signals according to the SS7 protocol.

VoIP comes as an outgrowth of the computers networking industry rather than the telephone industry. Its technology is based on IP packets and SIP switching rather than pulse code modulation channels and SS7. As you might expect, you can’t directly connect one system to the other. Analog and VoIP phone systems, including business PBX systems, connect or “terminate” their calls to the PSTN. The PSTN SS7 switches take care of getting the conversations connected from one proprietary network to another. Each time a call has to traverse the PSTN, there is a small but significant per minute access charge.

TW Telecom, a major competitive carrier, is looking to give the telephone system a nudge in the direction of eliminating the SS7 switching step. According to a recent report in Connected Planet, they are asking the FCC to classify voice calls over IP as a telecom service rather than the current status as an information service. That would get incumbent telephone companies, the heart of the old Bell system, to connect phone calls on an IP to IP basis. The benefits would include higher voice quality by eliminating the protocol conversions and lower network compensation costs.

TW’s actions are the first step in a process of creating IP Exchanges, similar to Ethernet Exchanges that share traffic between network providers and extending the reach of all Ethernet networks. It’s a matter of standardizing protocols and fees so that you have a level playing field without technical hiccups. It’s not the end of the beginning, but the beginning of the end for SS7.

Fixed Mobile Convergence Includes Android and iPhone

When we think of network convergence, it is generally in terms of engineering the LAN, MAN and WAN to support voice, video and data. Network convergence is at the heart of the productivity and cost savings offered by enterprise VoIP solutions. Even so, there is still one piece missing. That’s the mobile phone. This is where FMC or Fixed Mobile Convergence comes into play.

The idea behind FMC is that cell phones, especially smartphones, are now so ubiquitous that they have to be included in the corporate communications structure or there will be a big hole in the system. It’s especially true for sales people, field engineers, and anyone else who spends a significant amount of time out of the office and away from the desk phone. It’s also true, perhaps unfortunately, that we’re in a 24/7 world where important calls may come in at any time.

Some employees handle this situation with workarounds, such as setting up the office phone to forward to their cell phone when they leave the office. That’s fine when they remember. If not, voice mail becomes the communications method of last resort. Wouldn’t it make more sense to have the office phone system extended to include your mobile phone?

Smoothstone IP Communications thinks so and is now making their Mobile Connect app available to both Android and iPhone using customers. What Mobile Connect does integrate your smartphone into the enterprise communications platform. You then have one number, your work number, that rings on both your desk phone and your cell phone. When you place an outgoing call, the Caller ID reflects your work number, not your personal mobile number. Other calling features include access to the company directory, low cost international calling, 4-digit on-net dialing, visual voice mail and one-touch access to listen to and manipulate voice mail messages.

There are also advanced features from Smoothstone’s VoiceMAXX system that carry over to Mobile Connect. These include call recording and centralized call detail reporting.

VoiceMAXX is Smoothstone’s cloud based PBX telephone system. It relieves businesses of the need to invest in and maintain an on-premises PBX system, yet has the flexibility to integrate with and extend an existing PBX.

Cloud hosted PBX is a pay-as-you go proposition that easily scales to include more users as needed. With a cloud solution, you don’t have to over-provision your system to allow for growth. You simply buy more capacity as you need it. You also don’t have the agony of a “fork lift upgrade” that involves ripping out your old PBX and replacing it with a new one of higher capacity, more modern design or more features. All of those capital investment, installation, upgrades and daily maintenance tasks are taken care of by the cloud service provider. You just concentrate on those things that advance the business you are in.

Is your existing business telephone system creaking at the seams, or are you ready for the higher productivity that comes from advanced features such as fixed mobile convergence? If so, learn more and get pricing for cloud hosted PBX telephone services scaled to match the needs of your business, be it small, medium or enterprise level.

Rise Of The Cloud Hosted PBX

The days of the in-house PBX or Private Branch Exchange may be numbered. AireSpring, one of the fastest growing and most innovative of the competitive carriers, is now offering a cloud hosted PBX system they call AirePBX. With AirePBX, the PBX disappears but the phones remain.

In a way, we're going back in time to move forward. In the beginning, all switching was done at the telephone company central office and all phones were connected to the telco switch. Then came in-house telephone operator switchboards and later automated switchboards called Key Telephone Systems (KTS) and Private Branch Exchanges (PBX). What a cloud hosted PBX does is move the switching system back to the service provider.

So, how can you save money by going back to an earlier network architecture? A lot has changed in the last century. For one thing, the monolithic “Ma Bell” no longer exists. There are a lot of competitive carriers vying for your business. That alone offers better pricing options. Technology has also changed. Phones no longer need their own network. With VoIP, the telephone shares the same network as all the company computers, printers and other devices. The fact that you don’t need special proprietary wiring to connect to your phone service provider further increases competitive offerings and available features.

The idea behind a hosted VoIP system or cloud hosted PBX is that the expensive PBX system and its need for constant attention is taken over by a supplier who is in the PBX telephone business. That’s not the business you are in, is it? In fact, having to buy, install and maintain this equipment doesn’t really give you a competitive advantage at all. It’s just one more thing you pay for to get the communications services you need.

This is why companies are more than happy to ditch their venerable PBX in favor of a cloud solution. They are especially open to this alternative if their PBX is temperamental, nearing capacity, too old to be maintained, or too limited in features. Sure, you can go out and buy a shiny new model and do a “forklift upgrade.” Stop and think, though. Do you really want to shell out the thousands and perhaps tens of thousands of dollars needed for a new PBX, or would you rather pay as you go?

Let’s take a look at what AirePBX has to offer. You don’t have a PBX system in-house anymore. You just have IP phones plugged into your network and AireSpring provides those. No capital investment required. Each phone has its own voicemail. You can even get visual voicemail. Even though the PBX is hosted remotely, your internal call routing is still free, as are local outside calls. An auto-attendant is included to direct incoming calls. You can set up hunting for workgroups, add toll free numbers and virtual private numbers, have conference calls, and enjoy all the features you’d expect in a modern business phone system.

All of this is fully managed by AireSpring on their next generation IP backbone network to ensure voice quality and system availability. Compared to the often dicey performance of Internet VoIP implementations, this is head and shoulders better. AirePBX is an enterprise VoIP solution that scales easily for small and medium companies, too.

Are you in search of a better business telephone system for your company? If so, you may be surprised and delighted by the capabilities and low costs of the new cloud hosted PBX solutions. Why not get a quote for hosted VoIP phone services and see if you can have the business communications you need without the cost and aggravation of maintaining your own in-house telephone system.

Enterprise Cloud Communications Arrives

Cloud computing has been in the headlines as the next generation of information technology. What’s breaking out now is cloud communications, a move to make telephony as well as number crunching and file serving available as cloud services. You know it’s arrived when a provider the size of XO Communications launches an enterprise level cloud communications service.

In an odd way, what’s new is old. The origin of telephone services is in a cloud called the PSTN or Public Switched Telephone Network. Your basic phone is simply a client that derives its functionality from the massive telco switching network.

Then came in-house phone systems in the form of key telephone systems and PBX or Private Branch Exchange systems. These are essentially small phone companies that you own and maintain. All calls within the company stay on the internal system. It’s only when you need connectivity to the outside world that you have to rejoin the PSTN.

Telephone services are now moving back to the cloud, but with a difference. This time it's IP communications rather than switched circuits. It’s also not about a monolithic public network but private networking services with competitive features that go way beyond what the original telephone network was engineered to provide.

The new cloud communications offerings also go by the title of hosted PBX. The idea is that it is more efficient to establish a large IP switching center with a dedicated expert staff than for every business to be its own telephone company. The business users need only have the telephone handsets, speakerphone and similar desk equipment connected to their local networks. The large, expensive and hard to maintain switch moves out to the cloud.

Therein lies the key to cloud communications. It’s the rise of converged IP networks to handle voice, video and data, replacing separate dedicated networks for each. Once you’ve installed SIP phones on your LAN, it seems a bit inefficient to send that traffic to an in-house IP PBX system that connects to the PSTN with specialized analog and digital trunk lines. Why not keep all of the traffic on the converged network as long as possible?

That’s what XO says. They’ve built their business by creating an enormous fiber optic network footprint to provide digital connectivity to both businesses and other service providers. With an extensive converged network already in place, it’s logical for XO to add value by providing telephony solutions in their cloud. This way you have only one supplier for both network connectivity and the communication services running on that network.

The enterprise cloud communications model works especially well for companies with more than one business location. XO can tie your headquarters, regional offices and branches together as if they were in a single large facility. The converged WAN network give you all the standard calling features you expect in an enterprise telephone system plus high definition video conferencing and the ability to include mobile phones in a unified communications system. These communications services are priced on a per-seat-per-month basis.

Are you interested in upgrading your business communications while avoiding a massive capital investment? Look into future proofing your voice, data and video with hosted services in the cloud. Get pricing, features and availability on SMB and enterprise cloud communications services now.

Level 3 Shows How The Converged Business Network Saves Money

Network convergence has been an initiative for larger organizations since IP became accepted as the default network protocol. But smaller companies, with smaller or non-existant IT staffs, have paid little attention. That’s all changed recently. Now, convergence is for everyone.

Why the big change? The primary driver is cost savings, as it has always been. Cost savings has become an ongoing business process in this era of continuing austerity. But the real enabler is the availability of managed convergence. The carrier becomes your partner rather than simply a vendor. This relieves you of the burden of network management, especially WAN network management.

Level 3 has entered this space with its Converged Business Network solution. The idea is to use one bandwidth pipe for voice, Internet and VPN instead of three separate pipes. In one example, Level 3 replaces three separate T1 lines at 1.5 Mbps each with a single 3 Mbps connection that handles everything. That 3 Mbps link could be bonded T1 lines, or it could be one of the newer Ethernet services. They show stand alone services at $ + $ + $ being reduced to converged services for $.

A 3 to 1 reduction? That’s not unreasonable. After all, 3 Mbps Ethernet over Copper services are often priced about the same as a single T1 line.

How can you get a 3:1 line cost reduction without destroying quality of service? The answer is in two pieces. First of all, the bandwidth reduction isn’t that dramatic. You are going from 4.5 Mbps to 3 Mbps. Cost is going down faster than bandwidth. Second, the question assumes fully loaded line services. That’s seldom the case. Many companies have T1 lines because that’s the smallest commercial grade line service available to them. They wind up ordering 3 lines in order to keep voice, Internet and VPN applications separate so they won’t interfere. In reality, only a fraction of that available 4.5 Mbps is needed at any given time.

This is how a converged 3 Mbps WAN network can do the same job cheaper. QoS or quality of service controls are maintained on that connection so that time sensitive voice packets have priority over less time-sensitive data packets. At times when there are fewer telephone conversations in progress, that bandwidth is released for use by the broadband Internet or VPN services. This is called dynamic bandwidth allocation. In a situation with separate lines, any unused capacity simply goes to waste. It is not available for any other use.

A converged voice and Internet service called Integrated T1 has been on the market for years. However, its availability has been spotty and its focus has been on traditional analog and PBX telephony rather than the more advanced features of enterprise VoIP systems. Level 3’s service goes way beyond Integrated T1 with Ethernet connection speeds up to 100 Mbps as a standard package. That makes it an attractive service for medium and larger companies that long ago outgrew their T1 lines.

Is your company on the lookout for ways to save money while preserving quality of services? If so, you should inquire about the cost and benefits of network convergence. You could be missing out on a major advantage for your business.

How Voice over MPLS Expands Enterprise VoIP

Medium and large enterprises have been converting from traditional telephone and computer connections to VoIP over converged networks. The reasons are higher productivity and lower costs. But what happens when you connect your phones and computer network to the outside world? Do you lose the advantage of your enterprise VoIP technology?

Sadly, for some businesses, this is the case. Everything is efficiently connected over a high performance local area network. That network stops at the edge of the premises. In order to connect with other business locations, both voice and data must be transmitted over common carrier telecom services. This is true for each location. There is one architecture for the internal network and quite a different one for the transport service.

Typical interfaces include a PBX telephone system that connects to multiple outside telephone lines. These may be individual analog business lines or a digital ISDN PRI trunk line. In either case, the PSTN or Public Switched Telephone Network is used to make calls to both outside phones and the phone systems of the other company locations.

Computer networking is handled with point to point dedicated lines, often set up in a star network with headquarters doing the routing for all locations. This works well, but can be quite expensive when locations are on different coasts or in nearly every state. Add international locations and costs skyrocket.

What’s a better solution? The latest technology is MPLS networking. An MPLS network is a privately operated “cloud” network that uses a special tag switching system instead of IP routers to manage traffic. MPLS networks offer quality of service mechanisms so that real-time traffic, like voice and video, are unaffected by simultaneous data file transfers. That makes MPLS networks ideally suited to extending converged networks among as many locations as needed.

How can this benefit your organization? By interconnecting all of your locations through an MPLS network, you can create a seamless internal voice and data network for telephones and computer connections. Using an MPLS network to carry telephone traffic is known as VoMPLS or Voice over MPLS.

With VoMPLS, all of your internal telephone calls stay off the public phone network and you avoid toll charges. Only when you need to make an outside call do you need to connect to the PSTN. This can be an enormous cost savings compared to your monthly phone bill now. Similarly, the cost of using an MPLS network for file transfers can be considerably less than the cost of all those dedicated lines and the effort it takes to maintain a proprietary network. Plus, any productivity enhancements you’ve achieved by converging your voice and data networks can be shared among your other business locations.

Can Voice over MPLS technology offer you a significant cost reduction? Why now get cost quotes for a VoMPLS networking solution to links all of your business locations? The savings and performance can be impressive.

Broadview Networks OfficeSuite Brings The Cloud To SMB

As a small to medium size business, you’d like to embrace cost saving technologies like Enterprise VoIP, private IP networking and cloud services. But, oh, the investment to get into this game. You take another look at Internet-based services, but have serious concerns about quality and reliability of service. If only small to medium businesses without huge IT staffs could get the good stuff. But, wait, you can!

You can, indeed, upgrade to the latest in sophisticated telecommunications services without the big investment in dollars and staffing to do it all yourself. Broadview Networks has exactly the service you need in their OfficeSuite. It IS your office at one or many locations. You get the functionality of an enterprise-grade PBX or key telephone system. You get easy administration to add stations, sites and users through an ordinary Web browser. You get the ability to connect satellite and regional offices across the country with your main office using the same system and network. You get seamless communications with home-based employees and mobile professionals who have the same features and functionalities that are available on their office phones. You even get Internet access.

What you don’t get is grief and capital expenditures. OfficeSuite is a hosted VoIP system. That means that all the expensive and hard to maintain switching and server equipment is located in a Broadview Networks facility. They have the telecom talent to keep everything working 24/7 and enough resources to ensure that you can scale up your operation any time you want. What you have in your facility is telephones and computers connected to your 100 Mbps or 1 Gbps Ethernet LAN.

Now, be careful here. Not all hosted PBX solutions are the same. Some try to minimize costs by pressing the Internet into service as a telephone trunk line. Broadview Networks operates its own private network built on a redundant fiber-optic backbone. The difference between sending sensitive traffic, like telephone calls, over the wild and wooly Internet and sending them over a carefully controlled private network is the difference between take-what-you-get and dependable high quality performance. Broadview Networks can interconnect multiple locations through their converged MPLS network that maintains strict quality control on voice and data streams.

Then get complementary consulting and quotes on OfficeSuite and other quality hosted PBX phone systems. You’ll likely find that trying to be your own phone company is more trouble that it is worth.

What is a PRI in VoIP?

We tend to think of VoIP as a “new generation” phone service based on IP technology unrelated to the historical public switched telephone network. Well there’s some truth in that, but no matter what you implement you’ll still be dealing with the good old PSTN. The bigger your company or organization, the more “outside” phone lines you’ll need. You should take a close look at ISDN PRI to make the connection to all the phones that are not part of your enterprise VoIP telephone system.

What is a PRI? It stands for Primary Rate Interface. That’s telephony talk for a particular standard related to another telephone industry term, ISDN. ISDN is the Integrated Services Digital Network. There’s a history to the development of ISDN that relates to the once lofty ambition of replacing all analog home and business phone lines with digital versions. You may not have heard of this, as it fizzled when broadband Internet came along and usurped the data role intended for ISDN. Even so, the business version persists and is more popular now than ever. That’s what’s called PRI or ISDN PRI or even T1 PRI.

Why T1 PRI? It’s because ISDN PRI is physically transported on a T1 line. T1 is another telephone industry standard widely used in business for dedicated Internet and point to point data connections. T1 lines have the advantages of being provisioned on copper wires so you don’t need fiber optics installed. They can be extended to nearly any distance, are highly reliable and reasonably priced. The pricing has gotten really attractive lately due to all the competition in the industry. With all this going for it, T1 makes a great choice to carry PRI.

What’s different between a regular T1 line and a T1 PRI line? The line speeds and voltages are the same. What differentiates a PRI is how it is organized. Instead of a big chunk of bandwidth, ISDN PRI is set up as 23 channels that each represent one digital telephone line. A 24th channel is used for signaling and data such as Caller ID. It’s an upgrade to an older T1 telephone standard that was set up as 24 phone channels and no Caller ID.

The beauty of bringing in an ISDN PRI line or “trunk”, as it is called, is that you get 23 outside phone lines coming in on a single digital line. It’s a lot more compact and is almost always cheaper, usually a lot cheaper, than dealing with 24 individual analog business lines.

The interface is also generally very easy. Most PBX and IP PBX telephone systems either come with ISDN PRI capability or offer it through a plug-in module you can buy. All the circuitry to convert between 23 individual phone lines and the PRI digital trunk are implement on that circuit board. You simply plug-in one or more ISDN PRI lines and you have outside phone lines and a lot of them.

But why would you connect a T1 PRI to a VoIP phone system rather than keep it 100% VoIP? The simple explanation is that the rest of the world isn’t serviced by VoIP or at least the same VoIP provider. The only thing universal is the PSTN, where you can dial any number and get connected to any telephone in the world. Your enterprise VoIP phone system can save you a bundle on internal calls that stay on your own network. You can also buy a SIP Trunk that connects you to a telephone service provider completely in IP or Internet Protocol. But, guess what happens at that service provider when you want to call an outside number? That’s right. You’ll be switched through to the ISDN PRI lines that connect them to the public phone network.

Which is the best deal for your company when it comes to analog (POTS) phone lines, ISDN PRI or SIP trunking? Why not let an expert consultant get you competitive quotes for these various options so you make an informed decision? The service is fast, easy and free.

Telephony In The Cloud

Thinking about cloud networking, what normally comes to mind is meshed data networks transferring packets from location to location. But some companies are also moving their telephone services to the cloud. What advantages and challenges does this present?

In a way, the original public switched telephone network is the oldest existing example of a cloud network. It is a managed system, carefully engineered to assure availability and quality of service, that serves a vast number of users simultaneously. Each customer connects to the cloud via a direct line to the nearest cloud port at the local central office. Users don’t really care to know what goes on in those vast switching offices. They just want to be able to make a call from one location to another at will.

Some companies engineer their own telephone cloud networks using ISDN PRI digital lines to connect PBX systems at multiple offices. The advantage of doing this compared to using the public network is that you don’t have to pay for each call. Only those calls to and from the outside world are subject to a fee.

The more modern approach is to set up converged voice and data networks between business locations so that only one network need be maintained. MPLS networks are often used to implement this cloud network, as they are capable of maintaining quality of service at reasonable cost. On a large scale, this is known as enterprise VoIP. There may be only one IP PBX system at headquarters that coordinates all calls, or each location may have a smaller system. ISDN PRI trunk lines connect to the public telephone network for off-net calls.

SIP Trunking offers an alternative to the ISDN PRI trunk lines for transporting voice traffic. A SIP trunk is part of the VoIP system and acts as the network connection to a remote service provider. That service provider handles termination of calls to the public phone system as needed. Since they terminate calls for many customers, per minute costs can be lower than ordering phone lines locally.

Some companies go even further and get all their telephone services from the cloud. All they have is individual SIP telephones or analog phones with adaptors connected to their company LAN. A private line connection or SIP trunk connects to what is called a virtual PBX system at the service provider. It handles all telephone switching, on-net and off. This system is ideally suited to “virtual” companies that don’t have a bricks and mortar presence. The employees are scattered over a wide geographical area. Thanks to the virtual PBX, they are interconnected just like they would be within a physical office building. Even the receptionist is virtual, routing incoming calls by voice or keypad requests.

Would a cloud networking approach help your company improve productivity while reducing costs? You can find out with a simple inquiry to an expert consultant regarding enterprise VoIP telephone services.

A New Edge On Private IP Networks

So many companies have multiple business locations today, that IP network options have become cheaper and more available than ever before. A major player in this space is New Edge Networks, headquartered in Vancouver, Washington. New Edge specialized in private IP-based WANs (Wide Area Networks) that don’t use the public Internet. That gives them the edge on quality and performance in linking multiple business locations.

Why not the Internet? The largest network in the word certainly has proliferated over the last few decades. It connects just about everyone, everywhere on Earth at reasonable connection costs. That’s its advantage as a general purpose communications network and its limitation as a serious business network. Anyone and everyone can and do send just about anything and everything there is through the Internet. With network neutrality mandated, your critical transaction data gets exactly the same treatment as somebody on the other side of the globe Tweeting what they had for lunch.

The need for dependable performance, security and availability is what makes private networks attractive. Private networks are just that. They are privately owned and operated. There is no public access. Being a private entity, they are free to establish classes of service to guarantee that latency sensitive applications like voice and video conferencing have the priority to ensure low jitter and latency for optimum performance. New Edge, for instance offers six classes of service (CoS) on their network with service level agreements for each.

Strict control of network parameters makes possible the long desired goal of network convergence. Convergence merges separate data, voice and video networks into one single network that supports them all. Enterprise VoIP offers productivity features and cost savings, especially on a converged network. But voice is fragile, and your telephone calls can quickly turn to garbled mush on a “best effort” network like the Internet. Video conferencing, including telepresence services, also has great productivity and cost saving value. Like voice, real-time two-way video is fragile and breaks up with the slightest provocation. You need a solid network to support these high performance communication tools.

MPLS or Multi-Protocol Label Switching private networks, a specialty of New Edge Networks, give your business the opportunity to connect multiple locations on one fully meshed private network. Each location only needs an access network connection to the MPLS “cloud” network. New Edge offers a variety of connection options that include T1 lines, Ethernet, wireless, and even DSL.

Since most small and midsize businesses don’t have large full-time IT staffs to manage wide area network services, New Edge Networks offers full network management services, including the critical LAN/WAN interconnection. This lets companies concentrate on their core business activities while knowing that their wide area network is being well taken care of.

Does your company have more than a couple of business locations? If so, private IP networks may work to your advantage. Find out how you can improve performance and perhaps save money at the same time with high value MPLS network services from New Edge and other top tier service providers.
