If asking for support from Digium it is best to supply as much information as possible.
autosupport
There is an application called autosupport which gathers information from Asterisk and the operating system to assist Digium if diagnosing any problems.
wget http://svn.asterisk.org/svn/asterisk/trunk/contrib/scripts/autosupport -O /usr/sbin/autosupport chmod +x /usr/sbin/autosupport autosupport <case number>
In your home folder you will see a .tar.gz file staring with the case number that you have specified. this can be sent to Digium with your case details.
redirect console to file
Start Asterisk with the following
asterisk -gnrT | tee /tmp/<case number>-YYYYMMDD_cli-capture.txt
When in Asterisk set verbosity on 10 and debug to 10
core set verbose 10 core set debug 10 sip set debug on
Simulate the problem and then send the logs to Digium attached to your case.
