Hi,

[Note I posted this yesterday from the wrong email address.]

I am struggling to see why my SDP is not being set correctly on the INVITE to my supplier with Proxy-Authentication when I use uac_auth().

The initial INVITE to my supplier has correct SDP set by rtpengine_manage. Then supplier replies with a 407.  My failure route correctly handles the Auth, and also calls NATMANAGE again... but this time the SDP is unchanged and the private IP and original media information from the original device is relayed to my supplier.

kamailio.cfg isbased on the default config.  Running kamailio 5.4.6 and using example from uac module for uac_auth.

My failure route calls NATMANAGE.  Is there anything special about uac_auth?  Do I need some extra magic to apply the message body changes after I have run rtpengine_manage().

I can see that the NATMANAGEr test for nat_uac_test("8") is true, and rtpengine_manage() s being called.  But the outgoing SDP is not changed.

Thanks for any hints!

Paul

====================

Extract of kamailio.cfg

failure_route[TRUNKAUTH] {

    if (t_is_canceled()) {

        exit;

    }

    route(NATMANAGE);

    xlog("L_INFO","In failure route, just finshed NATMANAGE and now body is $mb");

    if(t_check_status("401|407")) {

        # $avp(auser) = "test";

        # $avp(apass) = "test";

        # $avp(apass) = "36d0a02793542b4961e8348347236dbf";

        if (uac_auth()) {

                t_relay();

        }

        exit;

    }

}
