[OpenSIPS-Users] Tls using t_relay

[Tito Cumpen]

Hey Bogdan,

Yes it seems like it continued down my routing script and tried to send it
locally as well
which is why I saw these
Apr 21 23:12:46 sip1 /sbin/opensips[11376]: ERROR:tm:msg_send: send() to
127.0.0.1:443 for proto tls/3 failed
when using the t_relay command. The remote end was sending provisionals but
the failure above was causing the internal error.

I've found a solution by using force_send_socket(tls:MY_IP:443); my tls port


and then rewriting the host port to the destination.
 rewritehostport("SIPAS:port");

should I be using the exit command after a t_relay to avoid this?

Thanks,
Tito
