dean, i would really love to implement something like this, but the problem is that because of ob draft you cannot assume that "UA will then end up registering to and forming a flow with both proxies in its assigned pair". in order cope with proxy failure, you must then play with all kinds tricks to make the still working proxy in the pair to assume the ip address and (in case of tcp) the flows of the dead proxy, which is not easy at all. -- juha _______________________________________________ Sip mailing list https://www.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
