If the intermediary proxy perform loose-routing (as specified in RFC 3261) then the ACK (as any other in-dialog request) would travel throught the proxies. If no intermediary proxy does loose-routing then ACK would be directly sent to the UAS. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
