Re: [SR-Users] Kamailio 4.16 - IMS Registration Failure

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 PING 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 ms 64 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 On Fri, Oct 17, 2014 at 6:07 PM, Carsten Bock <carsten(a)ng-voice.com>
