supported by the B2BUA is the Cisco TelePresence Advanced Media Gateway (Cisco AM GW).

The B2BUA can use the Cisco AM GW to transcode between standard codecs (such as H.264) and
Microsoft RT Video and RT Audio to allow high definition calls between Microsoft Office Communicator
(MOC) clients and Cisco endpoints.
