Description
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.
•
The H.323 Network Service of the RMX should register
it's dial prefix with the CMA gatekeeper.
•
When DMA is not used an Ad-hoc Entry Queue,
designated as Transit Entry Queue, must be pre-defined
on the RMX.
Multipoint Layout Application
Required for managing multi-screen endpoint layouts for
Cisco CTS 3XXX, Polycom TPX, RPX or OTX systems.
Polycom Converged Management Application - Gatekeeper
•
The gatekeeper must route calls to RMX based on the
RMX prefix registration on the gatekeeper.
Telephony, desktop and room systems.
•
H.323 endpoints must register to the CMA or IOS
gatekeeper.
•
Polycom SIP endpoints must register to DMA as SIP
Proxy when DMA is used.
•
H.323 endpoints must register to the CMA or IOS
gatekeeper.
