for example, lets say that UAS is pstn gw that needs to be contacted
over tls.  proxy 1 makes a decision to use this particular pstn gw,
rewrites r-uri so that it among other things contains transport=tls
parameter, and then forwards the request to proxy 2 that is a "dumb"
proxy whose purpose is to front end the gw.

i don't know another way to do this because sip uri scheme cannot be
upgraded to sips and sips scheme cannot be downgraded to sip.
