MCU Management
Polycom, Inc. 138
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
(kbps)
Select the minimum bit rate to which calls to this MCU can be downspeeded
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).
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 for
Preliminaries/Postliminaries and test the script with various variables.
