possible gateway problem?

Unanswered Question
Sep 18th, 2008

my operator in Singapore is complaining that sometimes when she receives a call, the callers can't hear her and eventually hang up. She has a 7960 phone. We running CCM 4.1.3 and gateway 2811 v.12.4(1r).

I have this problem too.

For random problems, more data is necessary.

CCM SDI, SDL trace

Sniffer capture from IP Phone to GW.

debug voice ccapi inout

Check logs in GW to see if some DSP is causing problems.
