I've had a recent complaint from my boss and nobody else seems to be having any problems. He says when put on hold (dead silence no hold music from other company) he gets disconnected after approximately 30 secs. No body else has come to me with this problem so far. Is there some sort of timeout setting after complete silence? I've looked all over the cisco unified CM administration and can't find anything nor have I found anything only so far. Any advice would be greatly appreciated. I'll try to provide any specific details that I can so feel free to ask.
