Hi, I am having trouble with dropped calls in Asterisk. I've done a bunch of searching but all I could find was setting busydetect and callprogress to yes in zapata.conf to help combat the problem, but I did this to no avail. The following is the output from /var/log/asterisk/full at the time the call was dropped on me. May 13 08:37:13 DEBUG[5379]: Stopping retransmission on '660440d07b1155645cabd0ce681609d9@10.125.1.245' of Request 102: Found May 13 08:37:16 DEBUG[8480]: Didn't get a frame from channel: SIP/cronus-116-78ed May 13 08:37:16 DEBUG[8480]: Bridge stops bridging channels Zap/1-1 and SIP/cronus-116-78ed May 13 08:37:16 DEBUG[8480]: update_user_counter(cronus-116) - decrement outUse counter May 13 08:37:16 DEBUG[8480]: Exiting with DIALSTATUS=ANSWER.

Faulty hardware perhaps? By the way I have a TDM400P with 4 FXO ports on it and have asterisk running on Debian 3.0. Thanks
