Summary:                    SIp channel stop work
Description: 
Asterisk 1.4.26.3 


It's a production enviroment.
We start asterisk in safe mode. 
Every minutes with sipsak we check if sip the channel replys to a keep
alive sip message. If doesn't replay we kill the process with -6 option and
the asterisk re-starts himself.

Attached yuo find the gdp output of the core file produced by the
operation.
I'm not able to understand if the gdp outout is helpful or not. The
problem is happened after 4 weeks of uptime. We have 1020 peer registered
on the asterisk and an average of 30 channels up during office time.

I have some doubts for example about the lines as:
orig_channame =
"SIP/openser_comtn-b0bd5470\000?\000\000\000\000\020?DA\000\000\000\000%4D\000\000\000\000\000`\002\221??*\000\000\b?B\000\000\000\000\000`\002\221??*\000\000?>N\000\000\000\000"

---------------------------------------------------------------------- 
the issue is that if I have a production machine with 1000 phones, and some
of them are critical, and the sip stak stops to work my first priority is
not debug the issue but restart the service. I'm using the kill command
becuase it's produce a core file. If I use a command like stop now I will
not have a core dump file and any info at all about.
The only possible choice that I see it's automatize the gdb debug in some
way before to kill the process.
