Poor call quality SIP trunk direct to CCM vs SCCP call - Any ideas?
I am beta testing SIP trunks to a VOIP provider, and the trunks terminate directly to the CCM 4.1 server.
Call functionality works fine. However call quality is poor. During a conversation when there is no speech, intermittent static can be heard or "background noise". When the remote party begins to speak, everything is clear and then again some "hissing" when they stop.
Normally I would associate this with VAD, however since the call is terminating directly to CCM and this option is disabled in defaults it should not be applied.
Oddly enough, calls from VPN spoke to VPN spoke or from Core to spoke over the same Internet feed are crystal CLEAR and sound amazing.
I would introduce a voice router (2800) to terminate the SIP trunks but would like to know if call quality will improve before the investment is made.

We are having issues with CM 5 but it appears to be related to the CM not releasing sip connections so after so many calls you get terrible voice quality. I am interested if you could steer me to how to terminate the trunks in a gateway rather than cm.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
