volte：401 Unauthorized

[King-Osmond]

Hello!

I have a problem about volte(401 Unauthorized).

P-CSCF:

4(4467) INFO: rr [rr_mod.c:515]: pv_get_route_uri_f(): No route header present.
4(4467) INFO: ims_registrar_pcscf [sec_agree.c:296]: cscf_get_security_verify(): No sec urity-verify parameters found

FOHSS:

Open5gs:

P-CSCF:

open5gs Yaml file
Yaml.zip

4g_volte_sip_error.zip

Can you help me see where the problem is？

Thanks!

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?

open5gs：v2.2.3
kamailio：5.3
