### Description
Hi, I am a junior with Kamailio, if I show you where I am wrong, I will. Often during a
call between two sip clients (located on the same subnet with pcscf) Kamailio P-CSCF
crashes with a core dump. But sometimes the call goes through normally, I can’t see why
this is happening.
<!--
-->
### Troubleshooting
#### Reproduction
It is reproduced often, the error is most likely somewhere with me.
<!--
-->
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.
