Hello,
I'm a bit new (to a recent versions) to OpenSIPS and trying it to act as a
UDP - WebSocket proxy using it as an outbound proxy in SIP client (PJSUA,
if it's important)
Currently I'm using 3.4.2 version.
Config is quite simple, not far from default one.
...
socket=udp:0.0.0.0:6051
socket=wss:0.0.0.0:9443
...
loadmodule "proto_udp.so"
loadmodule "proto_tls.so"
# WebSocket part
loadmodule "proto_wss.so"
loadmodule "tls_openssl.so"
loadmodule "tls_mgm.so"
modparam("tls_mgm", "client_domain", "localhost")
modparam("tls_mgm", "certificate",
"[localhost]/etc/ssl/certs/ssl-cert-snakeoil.pem")
modparam("tls_mgm", "private_key",
"[localhost]/etc/ssl/private/ssl-cert-snakeoil.key")
modparam("tls_mgm", "ca_list",
"[localhost]/etc/ssl/certs/ca-certificates.crt")
modparam("tls_mgm", "verify_cert", "[localhost]0")
modparam("tls_mgm", "require_cert", "[localhost]0")
...
route[relay] {
if ($socket_in(proto) == "UDP") {
$socket_out = "wss:0.0.0.0:9443";
} else {
$socket_out = "udp:0.0.0.0:6051";
}
if (!t_relay()) {
send_reply(500, "Internal Error");
}
exit;
}
I'm using most generic self-signed certs and just started to make some
experiments.
But when I'm trying just forward SIP packets to remote server, I'm getting
this in the logs

Server that I'm making connections to is supporting TLS and WSS transports.
If I'm changing socket type from WSS to TLS, all is working, so it's not a
TLS certificate issue or something like this.
I'm pretty sure, that I'm missing something obvious, but not really getting
what.
Would be appreciated for any hints.
