Hi Franz,

Thanks a lot for your support.

It's working fine with given zone-files.
Now, I could able to setup a call between two users, Please find attachment of tcpdump.

Small clarification, I have started capturing of tcpdump before starting of other components including hss. But I don't see any diameter messages in Wireshark traces(tcpdump).

Tcpdump traces call flow seems correct whereas same thing I was captured from my windows machine, Here call has been established but don't see call flow travels from different IPs.

Please find attachment of tcpdump and window machine Wireshark traces.

Any suggestion would be very helpful.

Thanks in advance!!

Yes, of course. That is the reason.
When the register request is processed by P-CSCF if forwards the request to an inbound proxy server of the target domain, and that is exactly the I-CSCF.
You have to modify the DNS entries for resolving the SIP domain accordingly.

I have quickly modified the zone-files for you. That should work now.
