Hi, I think I have finally figured out the direct or indirect cause of the problem. I was using trixbox 1.2 and later upgraded to 2.0 - latest and greatest. The problem can be reproduced in both. I have a Aastra 480i CT but I don't think its phone related. And here is my observations. When I talk loud consistently for 5-10 seconds, the call will be dropped. For a test, I shouted into the phone for 5-10 second, the call would for sure be dropped. If I talk softly in lower volume, the call will last. I think Asterisk is dropping it when talk vol is exceeded certain limit and the problem is not related to the phone. Any suggestion will be appreciated.

The problem has not occurred yet. Good to know that the 401 can be ignored. Will post it again when it occurs.

The "401" error is a normal challenge for "Register" authentication. You might need to keep your Ethereal or whatever sniffing tool open until the problem happens again. Cheers, Michael

What is the best way to track it down? Is there a way to log all call-terminations and the reasons associated with them?
