VoIP Trunk Service Providers

Any business with more than a few outside phone lines knows that trunk lines are the way to go. The next question is what type of trunk service to get. You might think that with a VoIP telephone system, the obvious choice is SIP Trunking. But is it? Take a closer look at what’s available and then decide.

The idea of telephone trunking originated with the phone companies back when Ma Bell ran the industry. When phones were new, a couple of wires were all you needed to connect from your location to the local phone company. Then everybody wanted a phone and businesses started installing switchboards to handle all the lines they needed. You know those old-timey photos of phone line congestion in the cities. That’s what happens when you build out one line at a time.

The mass of subscriber lines was gotten under control using multi-pair cable, often buried. But long distance lines between switching offices were another matter. The more simultaneous calls you carried, the more wires were needed. That gets expensive fast when you’re talking about dozens or hundreds of miles. Wouldn’t it be nice if one pair of wires could carry multiple conversations?

That’s the origin of the trunk line. The early systems were set up like radio stations on the dial, except over wires. Each call modulated its own carrier frequency that was spaced far enough in the spectrum from adjacent carriers so that they wouldn’t interfere. This was analog carrier telephony. The switch from analog to digital technology came with the T1 line. It’s been around for at least half a century and is still going strong.

T1 telephone trunks are divided into 24 separate channels, each transporting one two-way telephone call. All the dialing and switching is done on these channels, just as it would be on analog phone lines. You can get devices called channel banks to convert T1 to and from 24 analog phone lines at your office. The T1 line itself is two twisted pair running from your building to the nearest phone company central office.

The advantage of T1 lines as telephone trunks is that save a lot of wire and can save cost, too. There is no economy of scale when you buy your phone lines one at a time. Soon you have a dozen or two at the price of a dozen or two times the cost of one line. If you convert all those lines into a T1 telephone line (trunk), you’ll generally save money even if you only use half the capacity of the T1. If you need dozens of lines for your call center, T1 can save you a bundle.

Chances are that you won’t need a channel bank unless your phone system is completely analog. Most PBX systems have T1 ports already installed. Even the new IP PBX systems designed for VoIP telephones usually have T1 ports where you just plug in one or more T1 lines for your outside telephone service.

A closely related service that is even more popular than T1 telephone trunks is ISDN PRI. This service runs on a T1 line and is very similar to a T1 trunk. The difference is that only 23 channels are used for individual phone lines. The remaining channel is used for all the dialing, switching and data such as Caller ID. The switching is faster than with T1 telephony and most everyone wants Caller ID anyway. The port for this is called a PRI, ISDN PRI or T1 PRI an it is likely installed in your system now.

The other digital trunk option that is becoming popular thanks to VoIP is the SIP Trunk. SIP is the switching protocol used with IP telephones in a VoIP system. A SIP Trunk, which might also be carried on a T1 line, is not broken up into channels. Instead it is more like your local area network that transports Ethernet packets.

This is one of the big advantages of a SIP Trunk. It can connect directly to your network without having to convert from one protocol to another. In fact, just like your network carries both VoIP phone traffic and computer data traffic, a SIP Trunk can provide both telephone and broadband service from your service provider. This is the preferred arrangement, as it allows the provider to establish class of service controls to maintain voice quality regardless of other network traffic.

As you might suspect, an IP PBX system works well with a SIP Trunk. But SIP trunks can also be ordered with customer premises equipment that offers a T1 or ISDN PRI digital handoff or even analog phone lines.

Which type of telephone trunking service is right for your business? Compare prices, availability and options of T1, PRI and SIP Trunks to see what makes the best economic as well as technical sense for your particular situation.

MegaPath Merges Integrated and Hosted Voice

Telephone switching has migrated over the decades from the local telephone company to the enterprise and now out to the cloud. MegaPath is building a bridge from in-house phone systems to cloud telephony by adding hosted services to their Integrated Voice services. This could be the cost effective transition you’ve been looking for.

If all you are doing is buying a few analog business lines from your local phone company and running them through a small business phone system you got at one of the big box office stores, you’ve pretty much got what you are going to get. Small companies have a way of growing to become medium size companies, however, and a two or four line system with a half dozen desk sets is quickly outgrown.

This is where most businesses call in a local phone system dealer who installs and maintains a particular brand of business phone system. With an in-house PBX (Private Branch Exchange), you’ll be adding more outside lines but now you have the opportunity to shop around. You can get your analog lines from a competitive provider or move up to digital trunk lines to save money once you get more than 6 to 12 lines.

MegaPath, a major competitive carrier with a nationwide service footprint, has a service called Integrated Voice specifically tailored to SMBs with their own PBX systems. They provide the outside lines that connect your PBX system to the world. The interface can be traditional analog lines for smaller systems, T1-CAS or ISDN-PRI digital trunks for medium and larger systems, or SIP Trunking for the newer IP PBX systems that support enterprise VoIP.

The Integrated feature of Integrated Voice is that you get both telephone and broadband service over the same dynamic DSL, T1 or Ethernet connection. This is a bit different from simply adding a third party VoIP service to your broadband service. With Integrated Voice, the combined data/voice is carefully managed to ensure that voice packets have priority over data packets so that using your computers won’t cause the telephone calls to break up. Any time a phone wants to make or receive a call, the bandwidth for this is reserved from the Integrated pool. Bandwidth not used for phone calls is automatically assigned for broadband Internet access.

Integrated Voice services are popular with small to medium size businesses because nearly every business needs both telephone lines and broadband Internet access. You can pay for these separately or have a more efficient and cost effective solution that combines the two.

Hosted Voice is a different animal. With hosted services, you no longer have a PBX system on your premises. Instead, you use a much larger PBX that is located at your service provider. It’s as if the service provider has become the new phone company. All you have in-house are telephones. These can be traditional phones that connect to an adaptor called a voice gateway or SIP Phones that are designed to connect directly to your network.

Hosted Voice services, also known as hosted PBX, are popular with companies that haven’t invested in their own PBX system or want to avoid the capital outlay for a needed upgrade and the ongoing maintenance headaches. All of those issues move to the service provider. As a user, you don’t perceive that the phone system is in the cloud rather than in the basement of your building. You may also enjoy advanced features such as remote worker, find me/follow me, simultaneous ring, auto attendants and hunt groups that weren’t available on your old PBX system.

MegaPath has been offering both the Integrated Voice and Hosted Voice services. What they’re doing now is giving businesses the chance to add Hosted Voice features to their Integrated Voice service as an overlay to their lines or trunks. This offers the opportunity for companies to gain more features almost instantly without the headache and expense of completely redoing their phone system right away. It’s something of a hybrid cloud approach where some of the equipment is on-site and some is in the cloud at the service provider’s facility.

Are you interested in upgrading your current business phone system with more advanced features or getting a better price on phone lines and trunks? If so, check out Integrated and Hosted Voice Services for business locations to find the mix that works best for you.
