Hello community , 

on kamailio server i'm using the module "ims_usrloc_scsc" with the following configuration :

.........................................................

modparam("ims_usrloc_scscf", "db_url", "mysql://eyas:eyas@localhost/scscf")
modparam("ims_usrloc_scscf", "db_mode", 1)

modparam("ims_usrloc_scscf", "enable_debug_file", 0)

modparam("ims_usrloc_scscf", "matching_mode", 0)

modparam("ims_registrar_scscf", "error_reply_code", 503)

..........................................................

when i'm running kamailio and try to register i found the following :
