Network Configuration Guidelines

for VoIP

Real-time applications such as voice communications require a networking environment

that meets certain requirements to deliver and maintain good voice quality. The

following network configuration guidelines are highly recommended when using

AltiWare’s VoIP features.

ISP/Intranet Quality of Service (QoS)

• If you subscribe to the public IP network or use your own Intranet, make sure the

maximum network delay is less than 100 milliseconds.

• Also, the typical packet loss rate should be less than 1 percent.

WAN Bandwidth

The following table lists bandwidth requirements for various transmission media with

different codecs and frame sizes. It assumes silence suppression is not turned on. (The

same table appears on page 300.)
