Say, the UAS changes its contact details in the contact header of 200 OK response to an initial INVITE. Shall UAC send out the ACK to the original contact to which the initial INVITE was sent or to the updated contact address? [VR] In absence of Record-Route in 200 OK, UAC should send ACK to new contact address, Otherwise reverse of Record-Route will determine where ACK should be sent.
