Configuration of kamailio with websocket

[Fabien B.]

Here's the scenario:

1- Using jssip, I connect to kamailio and launch a call to kamailio.

2- Kamailio receives the jssip prompt via websocket on port 8080

3- kamailio now redirects the call to a SIP trunk configured on port 5060 using the udp protocol.

during the redirection, kamailio switches from port 8080 to 5060 to contact the SIP trunk and sends it a prompt, but the problem is that I don't receive any response from the trunk.
