MCU Management

Field

Description

 

 

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 Box on page 272). In this case, the

 

RealPresence DMA system selects the MCU/gateway and its session

 

profile. See ISDN Gateway Selection Process on page 139.

 

 

Class of service

Select to specify the default class of service and the bit rate limits for this

 

MCU.

 

If specified, calls to the MCU use its class of service or the calling endpoint’s,

 

whichever is better.

 

 

Maximum bit rate (kbps)

Select the maximum bit rate for calls to this MCU.

 

 

Minimum downspeed bit rate

Select the minimum bit rate to which calls to this MCU can be downspeeded

(kbps)

to manage bandwidth. If this minimum isn’t available, the call is dropped.

 

The minimum that applies to a call is the higher of the MCU’s and the calling

 

endpoint’s.

 

 

Permanent

Prevents the MCU’s registration with the Call Server from ever expiring. For

 

MCUs, this option should always be selected (the default).

 

 

Alert when MCU unregisters

If the MCU unregisters from the Call Server or its registration expires (if

 

Permanent is turned off), an informational alert is triggered (see Alert 5003 on

 

page 365).
