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.

I hope you will clarify this matter...
