We recently installed AAVID at a remote site. The Call Manager, E991 server, and gateway to our PBX are all at the main site. This has been up an running for a few months with no problems. Yesterday, users began compaining that, when talking to someone beyond the PBX, the far end user was reporting static and a robot-like voice quality. The IP phone users were not experiencing the same symptoms. Because we haven't experienced any problems previously, I am extremely new to troubleshooting voice issues. I'm looking at everything I know to look at and I can't find anything. I guess what I'm hoping for is some tips on what to look at and commands to do so. HELP!
