Hi Wilhelm,

Keep in mind that OPenSIPS is a routing engine that does what you tell 
it to do.

The OpenSIPS does the translation from TLS to UDP as the callee device 
is registered via UDP.

Now, how to handle a sips enforcement in the RURI is up to the logic in 
the proxy - if allows it to switch to a non-secure protocol or if 
applies constraints to stay with a secure protocol - but if you want 
this, you need to script it in your opensips.cfg.
