On further debugging looks below code in kamailio.cfg is failing

                if (!can_subscribe_to_reg("location")){
                        t_reply("403","Forbidden to SUBSCRIBE");
                        exit;
                }

In what case, can_subscribe_to_reg fails.., please let me know.

Thanks

This is a BLOCKING issue, we are totally stuck here.
Can somebody please guide us why SCSCF sends 403 to us.

Thanks

Hi All
In 4.2.0 Kamailio (S-CSCF), when I try to register an IMS endpoint, I get 403 from P-CSCSF.

When I checked the error logs, SCSCF logs look as below

 1(5455) INFO: ims_auth [authorize.c:824]: authenticate(): uri=sip:group4-imslab11.in nonce=b9eec0ad9d6d186408541d8a23a7c7a5 response=df89adebbf28f25d38d2f993f7cde033 qop= nc= cnonce= hbody=

I have added an user necs_0 in hss_db, so why I get below error.

Please let me know what is missed here.

Is S-CSCF not able to contact HSS ??

Best Regards
