Hello,<br>
<br>
can you send me ngrep/pcap file with ip addresses so I can match which
200ok is causing the problem (coming from B or coming from Asterisk)?
The backtrace shows ip while the sip trace is masked.<br>
<br>
Also, I would need a bit more info from the core file. Please keep one
around. The issue seems to be related to P-Asserted-Identity header,
but I couldn't find any such header in the sip trace you sent.<br>
<br>
Are you accounting the PAI header?<br>
<br>
Thanks,<br>
Daniel<br>

<br>
The scenario is as follows:
<br>
<br>
1. A Call is placed by a sip subscriber "A"
<br>
2. kamailio forwards the call to the asterisk server
<br>
3. Asterisk plays an IVR message on the subscriber "A", creates a new
call to a "virtual" number which is forwarded to the kamailio server,
and plays an ivr to this leg as well when the call is answered, then it
connects the two calls.
<br>
4. Kamailio translates the "virtual" number to the pstn number of
subscriber B
<br>
<br>
<br>
I have attached a picture of the above scenario.

Hello,
<br>
<br>
Can you give us more details like the sip message that generates the
coredump (or if every sip message received generates the core), if your
config does something more out of the ordinary(let's say exotic). Can
we reproduce it ?
<br>
<br>
It would also be helpful if you specify the list of modules you have
loaded.
<br>
<br>
Cheers,
<br>
Marius
