[OpenSIPS-Users] TLS traffic is being relayed as UDP but on the TLS Port?

[John Kiniston]

I have a proxy that works fine with UDP handling mid-registrar and
mediaproxy duties in front of my Asterisk Servers.

I'd like to enable TLS on my proxy and switch my phones to registering via
TLS.

I've got my TLS keys working now and I see my phone sending requests to
OpenSIPS where they are being processed.

However when OpenSIPS is sending the traffic to my Asterisk boxes it's
sending SIP traffic to port 5061 instead of sending TLS.

I believe this is because the initial request opensips is recieving from
the phone has 'sip' in the register?

What can I do here? I've tried playing with rewriting $du and $fs but that
doesn't seem to be working.
