Sure, but the example.com proxy has rules for whether to allow such or not. If it *doesn't* want to allow it, or it has no such alternate routes, then life sometimes gets super-ugly. [again don't shoot the messenger] Some (not all) of those proxies then pass the 302 back upstream, but change the contact URI's domain to the domain they're passing it back up to. In effect they do what they do for req-uri's of requests they send. -hadriel _______________________________________________ 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
