[SR-Users] Kamailio 4.16 - IMS Registration Failure

Fri Oct 17 14:50:29 CEST 2014

Dear Carsten
group1-imslab11.in points to same machine where all CSCFs are running.
In this case it is 192.168.1.100.

>From machine, where I run sip client, I pinged to group1-imslab11.in

*192:~$ ping group1-imslab11.in <http://group1-imslab11.in>PING
group1-imslab11.in <http://group1-imslab11.in> (127.0.0.1) 56(84) bytes of
data.64 bytes from localhost (127.0.0.1): icmp_req=1 ttl=64 time=0.025 ms64
bytes from localhost (127.0.0.1): icmp_req=2 ttl=64 time=0.033 ms*
What is painful is, I am not getting the way out..., how do I debug or
troubleshoot?

Please guide me where I need to concentrate...,

I doubt either DNS or dispatcher.list file....

Many thanks
Kamal
