RE: loud buzzing sound on intercom calls
It's hard to get anything that's operating in an almost pure digital environment to "buzz" these days. Could be a mis-match in Codec that occurs randomly but until its get more consistent it's going to be difficult to isolate. If it does get more consistent or seems to be happening to the person who makes the most calls I would set up Wireshark to record the RTP streams, which could be targeted at the phones IP address or the servers IP. I'd also look for a POE or power supply issue.

As I re-read the original description the part that gets my attention is that when you pick up the handsets the problem goes away. The phones microphone is very sensitive. Anyway it could be picking up something like PC vibration or fan noise on or through the desk?
