Hi David, Thank you very much for the response. I am afraid I must ask you to break that down as it is “beyond my pay grade.” Sorry for being such a novice. “Get the xml cdrs for those dropped calls” – Where do I get these? From the freeswith.log? “check the rtp statistics” – Where? How?

Might you you a clue.

She claims several a day. I have replaced the phone and the network cabling with no change. I have reviewed many log files. There are no errors reported and the calls all end with a hang-up, mostly from her leg but occasionally the other end. It happens inbound and outbound. It has just occurred to me that if the RTP stopped working, it would appear to be a dropped call to the user who would hang-up. Other users at this site report occasional or rare dropped calls, but the main problem is then receptionist who clearly gets most of the calls. They are NAT connections through a SonicWall firewall that I hate and may be the problem. The server (FS 1.8) is shared with other users/companies and is not NAT. Does anyone have any suggestions for diagnosing this maddening problem?
