Re: Voice Activity Detection

Hi,

Use the commands " vad " to turn voice activity detection on, and the " no vad " command to disable it. This is a valid command on both your dial peer statements and your voice ports. With dial peer statements VAD is enabled by default. With a voice port VAD is disabled by default.

Try this link for more information if needed:

Hope this helps.

Hi,

You can do this on the CallManager System Parameters.

There is a Mask Called "Silence Suppression System Wide".

Turn it to "False".

There is also a service parameter called "Silence Suppression with Gateways" also set this one to false.

Thank you,

Re: Voice Activity Detection

well, in mode privileged it makes the following one:

step 1

Use command " conf t"

step 2

in "conf t" it writes " voice vad-time ?" then VAD it will be OFF.

Luciano.
