Hello guys, I have an Asterisk installed (last version), and sometimes I have my calls hanged when I'm still talking to someone. I put the maximum debug to have informations about this problem and I found only one thing : Mar 10 01:26:16 DEBUG[16136]: Requesting Hangup because the busy tone was detected on channel Zap/1-1 Mar 10 01:26:16 DEBUG[16136]: Got a FRAME_CONTROL (5) frame on channel Zap/1-1 Mar 10 01:26:16 DEBUG[16136]: Bridge stops bridging channels SIP/remi-615d and Zap/1-1 Mar 10 01:26:16 DEBUG[16136]: Set option AUDIO MODE, value: ON(1) on Zap/1-1 Mar 10 01:26:16 DEBUG[16136]: Hangup: channel: 1 index = 0, normal = 18, callwait = -1, thirdcall = -1 Mar 10 01:26:16 DEBUG[16136]: Not yet hungup... Calling hangup once with icause, and clearing call Do you have any idea ? Thanks. Jean-Philippe Le Henaff togusa@labo-unix.org
