We have a T1 CAS and configured that gateway as H323. On some calls through that gateway (incomming or outgoing) we are experiencing clipping of the far-end voice.
I asked telco to ceck for bad tinmeslots on T1 and all is fine. Is it becasue of H323? Is there anything I can do, like change to MGCP? I m running ICS7750 Rev2, w/ CM3.1.2c and the T1 gateway is running IOS 12.2(4)XL1, EARLY DEPLOYMENT
