ppyy: is it possible to obtain a SIP debug from the console prior to the crash?

sabbathbh, we does not issue a "show channels".

serge-v, we have downgrade to 1.2.7.1, and i will try to catch the cash in a test platform later.

I need a SIP debug for this.

Please do the following:
1) Prepare test environment (reduce the amount of unrelated traffic on the server);
2) Make sure your logger.conf has the following line:
  console => notice,warning,error,debug
3) restart Asterik.
4) Enable SIP transaction logging with the following CLI commands:
set debug 4
set verbose 4
sip debug
5) Save complete console log to file and _attach_ said file to the bug.
 i.e. asterisk -Tvvvvvdddddgc | tee /tmp/sipdebug.txt

I do need more information, since the two core files are very different. Thanks.

Can you please return with more information, as well as test with latest 1.2 from svn. There's been a lot of changes to chan_sip lately. Thanks.
