John, The fact that the audio problems are solved by transferring from one phone to another would indicate to me that it's between the phone, and the Asterisk server. I take it that it's a direct connection through one switch from the phones to the server?
I have a client that received fairly heavy call volume, a few hundred calls a day, on IP501's using Static Queues on 1.2.13, and 1.2.14 (as of 2 weeks ago). They have experienced no similar problems, so I can't say "me too". What firmware version are these phones running? We use 2.0.1 with no problems. Can you get a packet dump from the server and see if it's sending the phone data?

We have a small install (8 extensions) using [EMAIL PROTECTED] with Polycom 501 SIP phones. Every once and a while one side of an incoming call's audio is missing. The callers can hear the employee but the employee can't hear the caller. They have been able to handle it in the past by transferring the call to another extension. To make this worse, it seems to only be occurring with two phones. We've replaced the phones three times and the report from the customer is that it fixed it, then a week or so later we hear that it's back. More oddities, is now they say they've had it occur on an outgoing call too. The two phones that it is occurring are in a static queue and most of the calls they will receive are from the queue. The reports from this customer are pretty sketchy, but they have been insistent about the audio problems. Any ideas. -- John Van Ostrand Net Direct Inc. CTO, co-CEO 564 Weber St. N.
