[SR-Users] Kamailio IMS deployment

Tue Feb 9 12:01:31 CET 2016

Hi Franz,

Thanks for your response.

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.
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”.

Please suggest me if I have missed anything.

Regards,
Sainath

The REGISTER request is OK.  There is no username included in REGISTER request.
Regarding the mismatch: do you use NATURAL on your platform?

Next step should be a tracefile (tcpdump) and later a debug-log from the node which shows the problem.

Please guide me for any more changes has to be done, As observed in Wireshark(Register request from 10.0.0.8(host)-PCSCF as REGISTER sip:net1.test SIP/2.0). I think the register request should sent as REGISTER sip:alice at net1.test SIP/2.0

Thanks in advance!!

Sainath,

what was the result for ping on
- icsct.net1.test
- scscf.net1.test
- hss.net1.test

to increase debug level you have to modify the corresponding cfg-file, e.g. kamailio-icscf.cfg in line 35: debug=2
Just increase to debug=3 and then start the process again.
