Hi,

I have a provider that requires proxy auth for all outgoing calls so I create the following config:

loadmodule "uac.so"
loadmodule "dialog.so"
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "track_cseq_updates", 1)
modparam("dialog", "send_bye", 1)
modparam("dialog", "timeout_noreset", 1)
modparam("uac","auth_realm_avp","$avp(s:auth_realm_avp)")
modparam("uac","auth_username_avp","$avp(s:auth_username_avp)")
modparam("uac","auth_password_avp","$avp(s:auth_password_avp)")

route {
        ......
        dlg_manage();

        # dispatch destinations to PSTN
        route(PSTN);

        ......
}

failure_route[MANAGE_FAILURE] {
        route(NATMANAGE);

        if (t_is_canceled()) {
                exit;
        }
        if (t_check_status("401|407"))
        {
                $avp(s:auth_realm_avp) = "realm";
                $avp(s:auth_username_avp) = "user";
                $avp(s:auth_password_avp) = "pass";
                if (uac_auth()) {
                        xlog("L_INFO", "[MANAGE_FAILURE] did auth. Relaying to new destination. from=$fu, callee-selected-by=$ou, uri=$ru");
                        t_relay();
                        exit;
                } else {
                        xlog("L_INFO", "[MANAGE_FAILURE] no matching realm found. realm=$ar");
                }
        }
}

Based on this authentication happens correctly however when canceling the call from the caller side, incorrect CSeq value is sent to the PSTN trunk:

Since I'm new to Kamailio, I figured I must be doing something wrong but don't seem to find any working example anywhere....

After installing from package, it works better but there are some issues still:

Now the CSeq is correct, however I do see repeated CANCELs and 487s from the peer just as in #870 This means that it does cancel the call and these extra messages back and forth do not cause any end-user side effects:

Would it be because the operator sends 487 before 200 (shouldn't it be 200 OK for CANCEL first then 487 as last message). #870 seems to have similar call flow.
