Summary:                    Segfault when answering ringing mobile while
monitoring call with mixmonitor
Description: 
When I try to answer call and playback welcome message before forwarding
to sip extension, asterisk crashes.

Note that call is monitored by mixmonitor.

Asterisk is trunk r. 80129
chan_mobile is addons trunk r. 426
System is openSUSE 10.2. Mobile is Nokia6230i.

gdb backtrace follows:


Core was generated by `asterisk -vvvc'.
Program terminated with signal 11, Segmentation fault.

Without call monitoring it seems to work. This might be an issue in
asterisk itself, not chan_mobile.

dbowerman: thanks for info, I'll retest it and give feedback as soon as I
get back my N6230i, probably during next weekend.
