[SR-Users] Kamailio 5.2.2 IMS authorization failed by the SCSCF

[YASIN CANER]

Hello,

you should check


  *   check realm parameter on function
  *   check user information in hss

even if there is a nonce paremeter in auth header , it always gives this error.

Subject: [SR-Users] Kamailio 5.2.2 IMS authorization failed by the SCSCF


Hi,



We are getting a SIP 401 Unauthorized -Challenging the UE error originating by the SCSCF.  It looks to be related to the nonce/cnonce.

Is there something we have misconfigured in our SCSCF module?



Log output:
