Description:Hi, we've got a problem with latest 1.4 (SVN branch) crashing whenever we make an outgoing call.

The backtrace pointed to the following code (which we're not using because we don't use video).  After commenting out this section we were able to make calls again.  If you need the full bt let me know.  Sorry I can't be of more help with tracking down the cause, I tried videosupport=yes/no, disallow=all, allow=ulaw etc. IAX2 calls worked, SIP not.  Same to three different providers.

We got a warning before the crash as well.

So here we go, warning:

[Oct 25 19:49:35] WARNING[16773]: translate.c:86 powerof: No bits set? 0

bt all:

#0  0x0000000000497a86 in ast_translate_available_formats (dest=Variable "dest" is not available.
) at translate.c:856
856                     if (!tr_matrix[src_video][powerof(x)].step)

patch we used (just a temp workaround):

ZX81: You should know the bug report guidelines... :-)

Where's the SIP debug so I can see what's going on? And the backtrace?

oej: although i'm not experiencing a crash and my outgoing calls seems to be fine. i will attach here my sip debug with set verbose to 9 this might help you to figure out what's really happening i'm running on SVN-branch-1.4-r46165M

This has been fixed in 1.4 and the trunk in revisions 46329 and 46330.
