MCU Management

Field	Description
Direct dial-in prefix	The dialing prefix assigned to the MCU, if any. MCUs without a prefix are
	unavailable for direct prefix-based dialing.
	MCUs don’t need a prefix to be used as conferencing resources by the
	Conference Manager.
	Gateways don’t need a direct dial-in prefix if you define simplified ISDN
	gateway dialing prefixes so that the RealPresence DMA system can choose
	from a pool of available gateways (see Add Simplified ISDN Gateway Dialing
	Prefix Dialog).
Signaling IP for H.323	The dialing prefix assigned to the MCU, if any. MCUs without a prefix are
	unavailable for direct prefix-based dialing.
	MCUs don’t need a prefix to be used as conferencing resources by the
	Conference Manager.
	Gateways don’t need a direct dial-in prefix if you define simplified ISDN
	gateway dialing prefixes so that the RealPresence DMA system can choose
	from a pool of available gateways (see Add Simplified ISDN Gateway Dialing
	Prefix Dialog).
Signaling IP for SIP	The address that the MCU uses for SIP signaling. If you specify the login
	information for the MCU, this field is optional (the system can get the address
	from the MCU). If not, and SIP is enabled, this field is required.
Transport type	The SIP transport type to use with this MCU. If the Polycom RealPresence
	DMA system‘s security settings don’t allow unencrypted connections, this
	must be TLS.
Signaling type	Select SIP, H.323, or both, depending on the configuration of the Polycom
	RealPresence DMA system and the MCU.
Enable for conference rooms	Makes the MCU available as a conferencing resource for the Polycom
	RealPresence DMA system’s Conference Manager.
	Up to 64 MCUs can be enabled for conference rooms.
	Caution: Before adding an MCU to the RealPresence DMA system’s
	conferencing resources, make sure that MCU isn’t already a RealPresence
	Resource Manager system conferencing resource. The RealPresence
	Resource Manager system must have exclusive use of any MCUs on which it
	directly schedules conferences.
Enable gateway profiles	Makes the MCU available for selection as an ISDN gateway device and
	enables the Gateway Profiles tab for configuring gateway session profiles.
	Gateway session profiles indicate to the MCU the bandwidth parameters to be
	used for the ISDN connection. They can be used for:
	• ISDN gateway calls to the MCU’s direct dial-in prefix. In this case, the caller
	specifies the session profile prefix in the dial string:
	<direct dial-in prefix><session profile
	prefix><delimiter><E.164 number>
	• Calls to simplified ISDN gateway dialing prefixes (see Add Simplified ISDN
	Gateway Dialing Prefix Dialog). In this case, the RealPresence DMA
	system selects the MCU/gateway and its session profile. See ISDN
	Gateway Selection Process.
