Hi,
I have configured the dispatcher default socket as below IP , the
expectation here is that kamailio should send all traffic from this IP
(port will be ephemeral) over TCP.
modparam("dispatcher", "ds_default_socket",
"tcp:172.27.45.219:5060")
This system also listens on port 8080 which is meant for websocket
communication (dispatcher communication is over non websocket).
Kamailio is sending an OPTION message to dispatcher IP over TCP on 5060 and
getting 200 OK response but Kamailio considering the response is on
websocket port 8080 ,$Rp value is 8080.
onreply_route {
if (($Rp == 8080 ) && !(proto == WS))
{
xlog("L_WARN", "SIP response received on $Rp
protocol:proto
RIP:$Ri SIP:$si method:$rm cid:$ci replystatus:$rs len:$ml\n");
xlog("L_WARN", "SIP message received: $mb\n");
drop;
}
.....
....
}
Following is the output of above logs:
