About the Call Server Capabilities
The Polycom RealPresence DMA system's Call Server capabilities provide gatekeeper functionality (if
H.323 signaling is enabled), SIP proxy server and registrar functionality (if SIP signaling is enabled), and
bandwidth management.
The system can also function as an H.323 <-> SIP gateway.
Note: Call server characteristics
In H.323, DTMF tones are usually sent over the H.323 signaling path. In SIP, DTMF tones are usually
sent over the media path as a special RTP payload packet (see RFC 4733). Because of this difference
and because the RealPresence DMA system isn't in the media path, its gateway function doesn't
support DTMF transmission.
The gateway function also doesn't support content sharing or AES encryption.
The RealPresence DMA system's gateway function is used only for calls to registered endpoints, SIP
peers, and H.323 gatekeepers. It's not used for calls to virtual meeting rooms (VMRs), virtual entry
queues (VEQs), external addresses, or IP addresses.
In addition, the system can be integrated with a Juniper Networks Service Resource Controller (SRC) to
provide bandwidth assurance services.
