To generate background noise to fill silent gaps during calls if voice activity

configuration mode. To provide silence when the remote party is not speaking
and VAD is enabled at the remote end of the connection, use the no form of
this command.

5.7.3.1.4. Usage Guideline
If the comfort-noise command is not enabled, and VAD is enabled at the
remote end of the connection, the user will hear dead silence when the
remote party is not speaking. In this case, there is no voice packet and it feels
like the call is terminated. So the Gateway generates background noise to
smooth the conversation- comfort noise generation. The default value is
“enable”. So it feels akward or prefer silence, deactives the function.
5.7.3.1.5. Example
The following example diables background noise on voice-port 1/0.
