Silence suppression

how to disable silence suppression?

Turn in off in your client (extension)

Ivan please don’t post sentence fragments and expect a cogent response.

You need to tell us where you want to disable it (in the phone, soft phone, telco interface).

We always need to know FreePBX, Asterisk and system info (how installed)

Also with questions like this need the hardware involved.

ivancornedi,
Can you tell me why you are looking to disable silence supression?

If calls are dropping because of being on hold or no audio transfer, try adjusting your RTP timers in Advanced SIP settings.
