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.

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@net1.test SIP/2.0

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.

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
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!!

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.
BR Franz
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!!

Hi Sainath,

Thats fine and congratulation.
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).
That is caused by the fact that the 3 involved diameter nodes (HSS, I-CSCF and S-CSCF) use 3 different ports for Diameter (3868, 3869 and 3870). Only port 3868 is the assigned port number to Diameter, the other two port numbers (3869 and 3870) are not. The reason for this is a historic one. The OpenIMSCore platform used one common IP-address for all tree nodes and therefore different port-numbers had to be used.
Wireshark has limited possibilities to automatically detect the protocol behind a stream when port numbers deviating from the assigned ones are used.You have to tell that to Wireshark. Just take the two packets (#10 and #17) and in your tracefile trace_12_2_2016_12.pcap and tell Wireshark "decode as Diameter" and you will see what you might have expected.
In your case, where you now succeeded to split the platform with different IP-addresses this constraint has gone. There is no reason to not use the same "assigned" port number 3868 for all three nodes. This could be the next challenge for you to reconfigure.
I have also added a message diagram produced with sip-scenario generator which helps a lot in debugging. Just extract both html files and open the one with the shorter filename (trace_12_2_2016_12_index.html). The sip-scenario generator is an open-source-tool but unfortunately with no support anymore. But it is really helpful. If you are interested I can provide the tool.
BR Franz
Hi Franz,
Thanks a lot for your support.
Traces decoded with diameter and could able to see the messages correctly.
Yes, I am interested to capture traces using sip-scenario generator tool. Can you please provide that tool.
Somewhere I have read in Kamailio forum that, Call setup has successful happened using "Boghe IMS client" and " Mercuro-Silver".
Currently We are trying to automate the basic call scenario using Boghe IMS client, It would be better if you can provide "Mercuro-Silver", So that call can be established between two different IMS Client. Tried finding in google for "Mercuro-Silver" but couldn't get it.
Thanks in advance!!

Hi, again
Thanks a lot for your support.
Yes, I am interested to capture traces using sip-scenario generator tool. Can you please provide that tool.
I have provided it at https://www.dropbox.com/s/nqay103s2rmnffq/sip_scenario.v1.2.7.zip?dl=0 .
Somewhere I have read in Kamailio forum that, Call setup has successful happened using "Boghe IMS client" and " Mercuro-Silver".
Currently We are trying to automate the basic call scenario using Boghe IMS client, It would be better if you can provide "Mercuro-Silver", So that call can be established between two different IMS Client. Tried finding in google for "Mercuro-Silver" but couldn't get it.
Mercuro Silver was a commercial IMS client provided by a company "Inexbee" which unfortunately does not exist anymore. The company offered 3 clients Mercure bronce, silver and gold. The Mercuro bronce was the free one. I have saved it here: https://www.dropbox.com/s/0pjmhi44c8blbyd/Mercuro%20IMS%20Client%20Bronze%20... and here is the data sheet: https://www.dropbox.com/s/81rleqfsvhyeqbc/Mercuro_Datasheet_V1R01.pdf?dl=0 The chief development engineer at Inexbee meanwhile has founded https://www.doubango.org/ with the client you are already using.
