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. -- juha _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
