Hi Franz,
Thanks for your response.
We are not using "NAT" in our network instead of that using
"Bridged".
As communication is not happening from P-SCF to I-CSCF, I don't see anything like
forwarding to I-CSCF in kamailio-pcscf.cfg. Here do we have anything files like pcscf.xml
as it is not available by default.
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.
Please find attachments of Tcpdump, kamailio-pcscf.cfg and pcscf.cfg.
Thanks in advance!!
Regards,
Sainath

HI,
Even we observed in Wireshark traces, no username is
included in
REGISTER request. Any changes required?
No, we are not using NATURAL in our platform.
The "NATURAL" has been an automatic spell checking of my tablet. It should have
been "NAT".
Observed there is no communication between PCSCF –
ICSCF while
registration and also attaching the tracefile(tcpdump) using command
“tcpdump -i any -s 3000 -w /var/tmp/trace_OpenIMS.pcap not port 22 and
not port 3306”.
As you can see in the trace: The P-CSCF forwards the REGISTER request to 10.0.0.9 which is
not the I-CSCF (and not prepared to receive such messages).
You should check the forwarding to I-CSCF in kamailio-pcscf.cfg.
Next time you should start with the trace also at startup of the x-CSCF to see that the
Diameter connections are up and running.
BR Franz
