I'll use this ticket as documentation.

ansible-playbook ims.yml

use icscf
INSERT INTO `nds_trusted_domains` VALUES (1,'ims.mnc070.mcc901.3gppnetwork.org');
INSERT INTO `s_cscf` VALUES (1,'First and only S-CSCF','sip:scscf.ims.mnc070.mcc901.3gppnetwork.org:5060');

P-CSCF and I-CSCF seems to be fine.
But the S-CSCF is crashing.

P-CSCF: I disabled the Rx interface towards the PGW and P-CSCF because the PGW denies requests. It could be fixed by configuration and HSS data.

I haven't figured out how to get gdb working with kamailio to catch the crash.

There has been multiple problem.
A crashe inside the lxc container creates a crashdump on the host.
Further I couldn't attach to the exact correct child with the gdb utility.
Maybe it could work when using remote gdb with an IDE?

I found the problem: uninitialized arguments in the scripting engine (c code).
Currently I'm having problems finding a good second phone.
