Description
The Cisco Aggregation Services Routers (ASR) Series
includes Cisco IOS XE Software Internetwork Operating
System - Gatekeeper.
It controls and manages real-time multimedia traffic flows
between IP/SIP network borders, handling signaling,
data, voice, and video traffic.
Polycom Distributed Media Application
•
DMA is an optional component but is essential if
Content sharing is to be enabled.
•
All SIP endpoints register to DMA as a SIP Proxy.
•
DMA should be configured to route SIP calls (with
CTS destination) to CUCM.
•
DMA can be configured with a VMR (Virtual Meeting
Room). Incoming calls are then routed to the RMX.
MCU:
•
Functions as the network bridge for multipoint calls
between H.323, SIP and TIP endpoints.
•
The RMX can be interfaced to CUCM using a SIP
trunk, enabling CTS to join multipoint calls on RMX.
Signaling goes through the CUCM while the media in
TIP format goes directly between the CTS and RMX.
•
The RMX must be configured to route outbound SIP
calls to DMA.
•
RMX must be configured to send and receive RTP
streams to and from the Service Provider's SBC.
Multipoint Layout Application
Required for managing multi-screen endpoint layouts for
Cisco CTS 3XXX, Polycom TPX, RPX or OTX systems.
Telepresence, desktop and room systems.
•
Polycom SIP endpoints must register to DMA as SIP
Proxy.
