configuration command. Use the no form of this command to disable this feature.

no vad
Syntax Description
This command has no arguments or keywords.
Default
Enabled.
Command Mode
Dial-peer configuration.
Usage Guidelines
Use the vad command to enable VAD. With VAD, silence is not transmitted over the network, only
audible speech. If you enable VAD, the sound quality is slightly degraded, but the connection
monopolizes much less bandwidth. If you use the no form of this command, VAD is disabled, and voice
data is continuously transmitted to the IP backbone.
This command only applies to VoIP peers.
Example
The following example enables VAD:
dial-peer voice 10 voip
vad
