Hello everyone. I'm trying to redirect a call directly through kamailio by modifying the $ru variable. Just wondering if this is the right method or if there is a better way to do it. thanks

If by "redirect" you mean "route", it's the right method.
Thanks. Actually i'm facing a wall. I want to route call from kamailio to another server. I use websocket in kamailio, when i make a call by websocket, kamailio send invite to the server but i don't get response but with udp all work fine.

Have you confirmed that Kamailio actually sends the call over WebSocket?
My Kamailio is configured to send call by websocket, i configured it following the docs. but i think the other server only accept udp protocol.

Well, that may be your problem, then. :-)
It all depends on who is going to be redirected: the call from Kamailio to a different endpoint, or the originator is informed to redirect the call?
In case you have an ingress client that sends an INVITE to Kamailio and Kamailio needs to inform the client that the call must be redirected to a different IP address, I use:
remove_hf("Contact"); # removes original contact header, if any append_to_reply("Contact: $myNewContactHeader)\r\n"); send_reply("300", "Multiple Choice");
If you only wish to redirect the call from Kamailio to a different destination endpoint, modifying $ru is enough.

Thanks. Actually, i want to redirect the call from kamailio via websocket to another server using udp.

Oh, so you're saying it doesn't work when the call comes _in_ via WebSocket, but works fine when it does via UDP, and in both cases, it is meant to go out as UDP.
1) Do you have TCP or TLS listener (listen= statement)? Most likely TLS in the real world, since you'll use wss://.
2) Do you have this type of xhttp event handler?
https://kamailio.org/docs/modules/5.8.x/modules/websocket.html#idm25
3) Do you have any logging in that event handler (xlog())? And if not, perhaps you should add some and see if the incoming WebSocket connection actually occurs as expected, and up from there?

Hello Alex, Sergio
look at the scenario:

from the trace image you shared, Kamailio seems to be doing things right: it sends INVITEs to remote endpoint 108.59.2.133:5060. However, it seems the remote endpoint is not accepting or is ignoring the SIP messages, so I would check: - is Kamailio sending to the correct IP:Port address ? - is 108.59.2.133:5060 listening ? - is Firewall at 108.59.2.133:5060 allowing requests from 65.21.159.66 ? - just to be sure, is the firewall at 65.21.159.66 dropping replies from 108.59.2.133 ? -
