I-cscf module not reading correctly UserAuthenticationAnswer - sr-users

17 Dec 2013

Hello everyone,
I'm using kamailio modules as Interrogating-cscf and Serving-cscf.
Registering an user i perform correctly an UAR and the HSS answers
correctly with an UAA giving user'c server-capabilities.

Even if i have a success result code ( as you can see in the attached
wireshark dump) the configuration code bring me in the failure branch.

 route[REG_UAR_REPLY]
...
  {
  xlog("L_INFO", "FB: received uaa");
  xlog("L_INFO",
"<<<<<<<<<<<<<<<<     
[$avp(s:uaa_return_code)]");
     switch ($avp(s:uaa_return_code)){
             case 1: #success
                     xlog("L_INFO", "FB:success");
                     if (I_scscf_select("0")){
                             t_on_failure("register_failure");
                             t_on_reply("register_reply");
                             #now relay to appropriate SCSCF
                             if (!t_relay()) {
                                     t_reply("500", "Error forwarding to
 SCSCF");
                             }
                     } else {#select failed
                             I_scscf_drop();
                             t_reply("500", "Server error on SCSCF Select
 (UAR)");
                     }
                     break;
             case -1: #failure
                      xlog("L_INFO", "failure");
                     xlog("L_ERR", "UAR failure - error response sent from
 module\n");
                     break;
             case -2: #error
                  xlog("L_INFO", "error");
                  xlog("L_ERR", "UAR error - sending error response
now\n");
                     t_reply("500", "UAR failed");
                     break;
             default:
                     xlog("L_ERR", "Unknown return code from UAR, value is
 [$avp(s:uaa_return_code)]\n");
                     t_reply("500", "Unknown response code from
UAR");
                     break;
     }
 } 

as you can see from my log i think tre's some problem when
reading UserAuthenticationAnswer return code.
