The B2BUA modifies only the CallID, the "to", and the "from" Headers. So the other informations will stay unchanged. For the server, it will be the B2BUA which will be Authenticated but really it will be the client. When the B2B UA receives a message from the server, it changes the 3 headers so for the client and the server dont know each other. > -Regards > -Regards > Asheesh.
