Voice And Data On One Line

Nearly all businesses today have a need for both telephone and broadband Internet service. Most businesses installed telephone first and Internet later. That’s led to a mix of line services to meet specific needs. Is there a better solution?

ISDN PRI is an excellent choice for PBX telephone systems.Today’s digital technology allows you to have both telephone service and broadband Internet access coming in on a single line. That often offers considerable cost savings over two separate services. But what about quality of service?

You might cringe at the thought of combined telephone and Internet if you’ve had a bad experience with VoIP over residential broadband. Usually it’s the phone service that suffers. Voices get garbled, you may hear an echo on the line, people start talking over each other with a delay in the speech, and calls can even be dropped. That’s what can happen when you just plug a VoIP phone or adaptor into a shared broadband service with uncontrolled bandwidth.

There are much better solutions available for business users. VoIP telephony can sound excellent and be as stable as traditional analog telephony. The trick is to carefully engineer the line to ensure adequate bandwidth, jitter, latency and voice packet priority.

A service called Integrated T1 does just this. A single T1 line with 1.5 Mbps dedicated bandwidth in both directions connects the business location to the service provider. There are no other users sharing this line. A specialized router called an Integrated Access Device converts analog telephony signals to digital packets. Those voice packets are assigned a portion of the line bandwidth to ensure they don’t get overwhelmed by data packets from Web sites and other Internet services. This bandwidth is assigned dynamically. As more phones are in use, more bandwidth is reserved for phone calls. When calls hang up, that bandwidth is reassigned for broadband Internet access.

Integrated T1 service works best for smaller businesses that need 6 to 12 phone lines plus modest broadband Internet service. It is possible to add more bandwidth as the business grows by bonding additional T1 lines.

Another service that combines voice and data on a single line service is called SIP Trunking. SIP is the signaling protocol used by enterprise VoIP telephone systems. You may already have a VoIP telephone system in your office. If so, you can get both voice and broadband Internet service over a SIP trunk. Like Integrated T1, SIP trunking manages quality of service to ensure that data and voice packets don’t interfere. SIP trunks, however, can have much higher bandwidth that T1 lines. Large SIP trunks can carry hundreds or even thousands of telephone calls.

Are Integrated T1 or SIP Trunking the right solution to give your company a substantial cost savings? Find out with a competitive service quote from Enterprise VoIP. You may be paying far more than you need to with your existing mix of telephone and broadband services.
