It seems the issue is related to some default configuration in IMS nodes in(pcscf, icscf and scscf). In pcap file, just pcscf node is appeared. please send full signaling flow in whole nodes. Thanks

Hello

I have a problem about volte(401 Unauthorized).

*P-CSCF:*

Can you help me see where the problem is？

Tips：About SQN, the SQN is the same at the beginning of the test (Open5GS, FOHSS), but when it is found that the sip registration fails, the SQN is inconsistent. If this situation is normal? If it is not normal, how to solve it?

I am not familiar with the IMS extensions, if nobody else comes with other suggestions, I recommend to set debug=3 in your kamailio configuration file and then look at the syslog, there should be a lot of DEBUG messages that may give more hints about what happens.

Also, when sending Kamailio logs, do not make screen shots, just copy and paste them, it is easier to read as well as search in the source code for them by copy&paste.

Cheers, Daniel

Just be notic, being behind nat, cause your request to pcscf is rejected and the same issue (No private identity specified) is appeared in lon info. The public identity (IMPU) and private identity (IMPI) are created with the same pattern by default as shown in your attachment, but the title of the issue is confusing.

================================================

The above content is found in the log of s-cscf,It seems that the authentication failed.

May I ask how to configure this part, or if this part of the code is deleted, will it affect the subsequent process?

Thank you very much！
