Hello everybody,
So i've a little problem with three phones. During a call this 3 phones work perfectly, but when nobody speak on call, i think the call drop, and when someone speak, the first part of his sentence is not heard, and this problem is systematic.
I try a firmware downgrade, but the problem still the same SCCP69xx.9-2-1-1-sr.zz (old) -> SCCP69xx.9-1-1-1-sr.zz (current)
Phone 6941 (SCCP)
Thanks for ur help

If your gateway is mgcp:
Do a 'show mgcp | i vad' on your gateway. You're looking for whether vad is enabled or disabled. No mgcp vad to disable.
If h323 or sip:
Check your gateway to call manager dial-peer(s) to ensure that vad is disabled (no vad).

Sounds like VAD. What are you using for call control and version?
