Administration
The various deployment combinations and settings within the Deployment Architecture affects the
administration of the system.
DMA
The DMA system can be configured as a SIP proxy and registrar for the environment as well as a
Gatekeeper for dial in H.323 calls. When configured as a Gateway for dial in H.323 calls, it enables H.323
endpoints to connect to the same VMR as SIP clients.
When used as a SIP peer, the DMA system can host video calls between Cisco endpoints that are registered
with the CUCM, Lync Clients that are registered with the Lync Server and Polycom endpoints that are
registered with the DMA system.
