What is latency and why is it important on a Digital Voice Network?
Latency is the length of time it takes for your words to be received by a listener at the other end of a phone connection, typically expressed in milliseconds. According to a white paper from Brooktrout Technology, latency starts to affect phone conversations when it exceeds 150 milliseconds each way, and is unacceptable when it exceeds 450 milliseconds (nearly half a second). The company recommends engineering a Digital Voice system so that latency is always below 200 milliseconds and suggests some ways to accomplish this task here. What are some ways to measure the performance of a Digital Voice network? Latency is the total of a lot of small delays that occur during the coding, transmission and decoding of a voice conversation. The time each step takes can be measured, and then improved through better network equipment and better configuration of the network. Performance factors within a business’s control include the presence of absence of a firewall for Digital Voice traffic; dela
