| Description: | Phone call (SIP TCP / SRTP) from some phone (here Snom 360, 7.3.7) to Asterisk 1.8.0-rc2. Asterisk answers and plays some sound file. CLI command "core restart when convenient" will cause segmentation fault if issued during call and SRTP is used. ****** ADDITIONAL INFORMATION ****** gdb backtrace [default] exten => _X.,1,Verbose(2,${CALLERID(all)}) exten => _X.,n,Answer exten => _X.,n,Wait(1) exten => _X.,n,Playback(tt-weasels) exten => _X.,n,Wait(1) exten => _X.,n,Playback(tt-weasels) exten => _X.,n,Hangup | ||
| Comments: | By: Stefan Schmidt (schmidts) 2010-10-04 00:29:31 it looks like it crash on shutdown itself when asterisk tries to remove the sip dialog. does this happen directly after your command restart or when the call is finished? By: Stefan Tichy (st) 2010-10-04 04:16:10 It happens when the call is finished.
