Hi,
One more thing observed in tcpdump, In DNS answer
getting IP of
server.net1.test(10.0.0.9), This might be issue that REGISTER request is trying
to communicate with 10.0.0.9 instead of 10.0.0.11(I-CSCF). Please any
suggestions.
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.
