[SR-Users] Route Between WebSockets without rtpengine getting into the mix

[Don Fanning]

Hello All,

Prior to going down the rtpengine path for another need, calling was
working fine between WSS client.  Now that I've added in some pieces from
caruizdiaz's config [
https://github.com/caruizdiaz/kamailio-ws/blob/master/kamailio-ws.cfg]
relating to SETUP_BY_TRANSPORT, it has broken that functionality.

Is there a way to skip rtpengine if the originator and destination are both
on wss?



route[RELAY] {

        # enable additional event routes for forwarded requests
        # - serial forking, RTP relaying handling, a.s.o.
        if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) {
                t_on_branch("MANAGE_BRANCH");
                t_on_reply("MANAGE_REPLY");
        }
        if (is_method("INVITE")) {
                route(SETUP_BY_TRANSPORT);
                if(!t_is_set("failure_route"))
t_on_failure("MANAGE_FAILURE");
        }
        if (!t_relay()) {
                sl_reply_error();
        }
        exit;
}

route[SETUP_BY_TRANSPORT] {

        if ($ru =~ "transport=ws") {
                xlog("L_INFO", "Request going to WS");
                if(sdp_with_transport("RTP/SAVPF")) {
                        rtpengine_manage("rtcp-mux-demux trust-address
replace-origin replace-session-connection ICE=force DTLS=passive");
                        t_on_reply("REPLY_WS_TO_WS");
                        return;
                }

                #rtpengine_manage("rtcp-mux-demux trust-address
replace-origin replace-session-connection ICE=force DTLS=passive RTP/SAVP");
                t_on_reply("REPLY_FROM_WS");
        }
        else if ($proto =~ "ws") {
                xlog("L_INFO", "Request coming from WS");
                rtpengine_manage("rtcp-mux-demux trust-address
replace-origin replace-session-connection ICE=remove DTLS=passive
RTP/SAVP");
                t_on_reply("REPLY_TO_WS");
        }
        else {
                xlog("L_INFO", "This is a classic phone call");
                rtpengine_manage("replace-origin
replace-session-connection");
                t_on_reply("MANAGE_CLASSIC_REPLY");
        }
}

Thanks for any help!
