The core file is too large to attach so you can get it here (11Mb):

Core files are only usable by the machine that created them so they are not wanted in the issue tracker.

See
https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace
to collect all the usual information for crashes.

Thanks, here is the "bt full".

This looks very similar to ASTERISK-18682, which was fixed in the 1.8 branch.  Can you retest using a checkout of 1.8?  The crash in that case was usually reproduced easily by pressing a DTMF key while a video stream was being played back in VoiceMailMain.

Thanks you - is this available from any particular Asterisk release, or must I use the latest from subversion?

By: Matt Jordan (mjordan) 2011-12-08 11:18:24.442-0600

This is only in the 1.8 branch at this time.  Please let us know if testing with the 1.8 branch resolves this issue for you.

Thanks, we are asking the customer to try the latest code.
By: Matt Jordan (mjordan) 2012-01-26 08:47:56.192-0600

Suspending for now as this appears to be resolved in ASTERISK-18682.  If this is still an issue please let a bug marshall know in #asterisk-bugs and we will reopen this issue.
