Voice Over Internet Protocol (VOIP)

Business Quality Voice

Independent tests of VOIP systems have shown that they are perfectly capable of delivering “toll-quality” voice. The actual voice quality your business will experience, however, is affected by a number of factors: WAN bandwidth (the higher the better), voice compression and network conditions such as latency (average “travel” time it takes for a packet to pass through the network).

On a private Intranet you can control all of these factors to achieve near toll-quality voice connections. When using the public Internet, you can control everything but the latency factor. Latency, however, can be managed to enhance your voice quality with a quality of service guarantee from your ISP. 

When network traffic is at peak levels, voice can be given priority over data to ensure consistently high voice quality using the Differentiated Services (DiffServ) Quality of Service (QoS) protocol. Other features such as forward error correction, bad frame interpolation and dynamic jitter buffers, can further enhance voice quality.  “We made hundreds of test calls using the (MultiVOIP’s) outside lines, and most people we called couldn’t tell that we weren’t on a standard long distance line.”
