[SR-Users] Trying to drop invite 200ok reply in onreply_route

[nikita]

Hello,

I'm using kamailio 3.0 with mediaproxy and I want to cancel calls if I have no mediaproxy relay connected to my mediaproxy dispatcher.

In my request route I'm checking if "use_media_proxy()" is returning me a positive result and it's working fine :

        use_media_proxy();
        if($rc < 0) {
                 sl_send_reply("480","Temporarily Unavailable");
                 exit;
        }


But I'm also want check in my onreply_route If I still have an active relay because I need to rewrite the sdp in the 200/OK reply.
My problem is that I don't know how to end the transaction, I have tried :

        if (is_method("INVITE") && status == "200") {
#!ifdef WITH_MEDIA_PROXY
                use_media_proxy();
                if($rc < 0) {
                        xlog("L_ERR", "invite reply error $rc \n");
                        dlg_bye("all");
                }
#!endif
        }

and also :

        if (is_method("INVITE") && status == "200") {
#!ifdef WITH_MEDIA_PROXY
                use_media_proxy();
                if($rc < 0) {
                        xlog("L_ERR", "invite reply error $rc \n");
                        drop();
                }
#!endif
        }

In both case I'm seeing in my log file that use_media_proxy() returned me -1, but the reply is routed to the caller ...

Any idea on how I can cancel my call in the onreply_route ?
Also, I don't know if it's a good thing to make a second call to "use_media_proxy" in the onreply_route, mediaproxy module couldn't reply me with a different relay address if I have multiple mediaproxy relay?

Regards,
