MCU Management

Field	Description
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).
Gateway Profiles
Copy from entry for ISDN gateway	Lets you copy the delimiter and session profiles from another ISDN gateway
	instead of entering them below.
	This is especially useful for MGC devices because each ISDN network card
	must be registered separately, but all cards support the same gateway
	configuration.
Dial string delimiter	The dial string delimiter used to separate the session profile prefix from the
	ISDN E.164 number.
Session Profile table	Lists the defined session profile prefixes. A session profile prefix is a numeric
	dial string prefix that specifies a bit rate for the call and which protocols it
	supports.
	Click Add to add a session profile. Click Edit or Delete to change or delete
	the selected profile. You can’t change or delete session profiles that the
	MCU/gateway registered with, only those that you added.
Media IP Addresses
Add new media IP address	If you specify the login information for the MCU, the system can get media
	addresses from the MCU. If not, enter an IP address for media streams and
	click Add to add it the list below.
Media IP addresses	List of media addresses for the MCU.
	Click Remove to delete the selected address.
Postliminary	A postliminary is an executable script, written in the Javascript language, that
	defines dial transformations to be applied before routing the call to the
	MCU/gateway.
Enabled	Lets you turn a postliminary on or off without deleting it.
Script	Type (or paste) the postliminary script you want to apply. Then click Debug
	this script to open the Script Debugging Dialog Box for
	Preliminaries/Postliminaries and test the script with various variables.
