I've trimmed the backtrace that you've posted in the additional information. In the future, it would be best if you attached the backtrace output as a file, and not directly into the issues since it makes the issue page quite long.

Also, you'll need to reproduce this issue and attach a new backtrace after you've enabled the DONT_OPTIMIZE flag in the Compile Flags within 'menuselect'.

Once enabled, run 'make install' in order to recompile and install the files. Then attach the newly generated backtrace output as a file once you've reproduced.

Thanks!
By: Kevin P. Fleming (kpfleming) 2009-08-17 14:10:30

We actually don't need the backtrace here, the provided backtrace is adequate to see where the code broke. However, to be able to understand how it got to that point, we'll need a complete console log including 'core set verbose 10', 'core set debug 10' and 'sip set debug on'; please ensure that the 'debug' and 'verbose' logger levels are mapped to the 'full' logger channel in logger.conf and then attach the portion of the full log that relates to these calls. Thanks.
By: Kevin P. Fleming (kpfleming) 2009-08-17 14:27:29

We are also going to need the relevant sip.conf entries for the two SIP endpoints involved in this call; it appears as though one of them may have t38pt_udptl disabled and that is somehow causing the code to misbehave.
By: sybasesql (sybasesql) 2009-08-17 15:02:36

Exactly! I catch that today too.
I have t38pt_udptl=yes in global section in sip.conf, t38pt_udptl=yes for one endpoint and t38pt_udptl=no for endpoint which calls cause asterisk crash.
When I set t38pt_udptl to yes asterisk stop crashes.
Unfortunately it's very difficult to make debug build because its production environment with many sip endpoints, but I try do something to accomplish your requirement.
Thanks!
By: Kevin P. Fleming (kpfleming) 2009-08-17 15:09:56

Don't worry about doing that just yet; with that confirmation of your configuration, we'll probably be able to reproduce this issue.
By: Kevin P. Fleming (kpfleming) 2009-08-17 15:11:29

If you can tell us, which of the two endpoints (t38 enabled or disabled) is the one that sent you the T.38 reinvite?
By: sybasesql (sybasesql) 2009-08-17 16:09:14

This is incoming call to customer with t38pt_udptl set to 'no' for his peer.

Short scheme:
PSTN --> E1 ISDN PRI --> cisco as5400xm --> SIP-t38pt_udptl=yes --> asterisk-1.6.1.4_x64 --> SIP-t38pt_udptl=no --> asterisk-1.6.1.4_x86(customer)

As described in Description section above and that scheme:
SIP/YYYYYYY = t38pt_udptl=yes = cisco as5400xm
SIP/7499XXXXXXX = t38pt_udptl=no = asterisk-1.6.1.4_x86(customer)

Hope this helps.

There have been some significant changes in the 1.6 branches related to T.38 support that are not included in the 1.6.1.4 release; using a current 1.6.1 branch checkout from Subversion, I cannot reproduce this problem. Receiving a T.38 reinvite from a peer with t38pt_udptl set to 'no' properly causes a '488 Not Acceptable Here' response to be sent back, and the call continues in audio mode as expected.

If you are willing to try it you can try the 1.6.1.5-rc1 release candidate which also contains these fixes, and is scheduled to become a full release in the next few days.
By: sybasesql (sybasesql) 2009-08-19 10:53:34

I'll try reproduce crash with asterisk 1.6.1.5 when it will be released and report results here.
By: Kevin P. Fleming (kpfleming) 2009-08-21 15:39:11

It would really be most helpful if you can test with the release candidate that is already out there, because if this bug is still present this issue will be a blocker for that release becoming a full release.
By: Kevin P. Fleming (kpfleming) 2009-09-01 15:35:22

Asterisk 1.6.1.5 has now been released; have you had a chance to do any more testing?
By: sybasesql (sybasesql) 2009-09-01 16:25:49

We are planning install 1.6.1.5 update on our production server where crash exists at Saturday and I'll submit report.
By: Leif Madsen (lmadsen) 2009-09-08 13:11:22

Just pinging this issue to see if the reporter has any additional information. Thanks!
By: Leif Madsen (lmadsen) 2009-09-30 09:24:33

I'm closing this issue as it has been waiting on feedback for more than 2 weeks. If the reporter has additional information that can be submitted, than they are welcome to reopen the issue. Thanks!
