Hello,

perhaps you don't force the rtp proxy properly for the branches. Try to force rtp proxy always just to see if it works, then look to see when you don't do it.

If you can paste the ngrep output for such call here, we can see if the rtpproxy is not engaged properly and for which branch.

Cheers,
Daniel

Hi, since few days ago I have many problems with the redirections in kamailio (3.1.1).

The blind forwarding works fine, but the redirection don't.

Here's my code:

failure_route[FAIL_ONE] {
xlog("L_INFO", "entering failure_route for reply code $T_reply_code\n");

        if (is_method("INVITE") && (isbflagset(FLB_NATB) || isflagset(FLT_NATS))) {
                unforce_rtp_proxy();
        }

        if (t_is_canceled()) {
                exit;
        }

      if (t_check_status("486|408|302"))
        {
                xlog("L_NOTICE", "r[FAIL] / &ru TimeOut or Busy\n");

                if(avp_db_load("$ru/username","$avp(s:callbusy)"))
                {
                        xlog("L_NOTICE", "Callbusy activado!\n");
                        avp_pushto ("$ru","$avp(s:callbusy)");
                        xlog("Redireccionando a $ru");
                        km_append_branch();
                        route(CONSISTENCIA);
                }
               t_relay();
        }
}

route[CONSISTENCIA]
{
      xlog("L_NOTICE", "KAM-INFO: r[CONSISTENCIA] / - CONSISTENCY FOR FORWARDINGS \n");
        route(NAT);
        route(ALIAS);
 }

When I make a call to a contact that is using the phone in this moment, i receive a 302 status code, instead of 486.

The big problem is this, I make the call, the forwarding works well and call rings in the right destination but i can't hear anything until the primary destination terminates the call.

Any help will be apreciated.

Best regards.
