will try and check.

HI Team/Yuncheng,

Can you please help me to TS the above issue.

Yuncheng,

The link/PW which you have shared is not visible currently could you please help.

Thanks

Always upload a pcap trace taken while you register the UE in order to debug. Logs are not always helpful

[ajaydas03]

Hi Supreeth,

PFA,

pcscf100pcap.txt

[herlesupreeth]

Thanks.. Couple of observations, I see that your UE is in the same subnet as P-CSCF, why? Also, looks like you are not using this repo. If you are not using this repo its hard to debug without knowing your test setup.

Second, the Contact SIP header sent by the UE is wrong, it should be sip:[email protected]

[ajaydas03]

Supreeth,

We are using your repo only, the only thing is we used our own subnets and tried testing with different "IMSI".

Also for your information we had achieved the first IMS registration successfully after that we started the debugging about 2nd UAR/UAA which we did not get after 401 (challenge response to S-CSCF).

Will check further as per your observation and let you know if gets resolved or any new issue come.

Thanks

[ajaydas03]

Supreeth,

Registration issue have been resolved now. I rebuild and did not make changes on your repo.

Just one thing to clear as per IMS registration call flow I-CSCF should query with HSS (UAR/UAA) post 401 unauthorized as I-CSCF is stateless proxy but i am not seeing that.

Please help here to clarify.

Thanks

[herlesupreeth]

I-CSCF has to query HSS and it does. If you could take a pcap on the machine running docker_open5gs when you attempt registration of UE and post it here I can show it to you

[ajaydas03]

Hi Supreeth,

As suggested i ran the pcap in same machine where docker_open5gs is running.

Please find the pcap.

Thanks

[herlesupreeth]

here you can see UAR and UAA

[ajaydas03]

Hi Supreeth,

As we know that I-CSCF is stateless proxy, so it does not store any information. post 401 unauthorized there should be one more UAR/UAA also as per call flow that i wanted to clear. but looks like code is written only for first UAR/UAA diameter message.

Please find the IMS registration call flow SS.
