[SR-Users] 403 Forbidden for INVITE in kamailio for ims call

[Priyaranjan Nayak]

Hi All,

I have installed kamailio and using as a i-cscf,s-cscf and p-cscf server. I
have taken FHoSS(OpenImscore) for hss server Now I am able to do register
and unregister. When I am sending INVITE for call, the calling-party and
called-party were registerd but I am getting "403 Forbidden - Dialog not
found on S-CSCF or Terminating user not suitable for unregistered
services".

Could you please tell me what is the root cause of above error message ?

Best regards,
Priyaranjan
