Usage Gui<strong>de</strong>lines<br />

This command first appeared in Cisco IOS Release 11.3(1)T.<br />

Use the vad command to enable <strong>voice</strong> activity <strong>de</strong>tection. With VAD, silence is not transmitted over<br />

the network, only audible speech. If you enable VAD, the sound quality will be slightly <strong>de</strong>gra<strong>de</strong>d but<br />

the connection will monopolize much less bandwidth. If you use the no form of this command, VAD<br />

is disabled and <strong>voice</strong> data is continuously transmitted to the IP backbone.<br />

This command is applicable only to VoIP peers.<br />

Example<br />

The following example enables VAD:<br />

dial-peer <strong>voice</strong> 10 voip<br />
