Voip Interoperability: Gatekeeper Configuration; Using Cs 1000 As A Gatekeeper - Nortel BCM50 Configuration Manual

Chapter 45

VoIP interoperability: Gatekeeper configuration

The following describes the use of a gatekeeper for your H.323 VoIP trunks.
Refer to the gatekeeper software documentation for information about changing IP addresses.
Gatekeeper notes:
• The BCM has been tested by Nortel to be compliant with CS 1000 gatekeeper applications.
• A gatekeeper may help to simplify IP configuration or the BCM dialing plan; however, it does
not simplify the network dialing plan.

Using CS 1000 as a gatekeeper

Both the BCM and the CS 1000 must be set to the parameters described in the following
information for the gatekeeper to work effectively. Refer to IP Peer Networking: Installation and
Configuration (553-3001-213) for detailed information on configuring a CS 1000 gateway.
For CS 1000, the Network Routing Service (NRS) can be configured and maintained through a
web interface called NRS Manager. NRS Manager replaces the CS 1000 GK admin tool.
Review the following information before attempting to use the CS 1000 as a gatekeeper:
• Before a Gateway Endpoint registers with the CS 1000 gatekeeper it must first be added to the
gatekeeper configuration.
• Before a registered Gateway Endpoint makes calls, it must have its routing entry information
assigned within the gatekeeper configuration.
• Before any of these configuration changes become part of the gatekeeper active configuration,
they must be committed to the active database.
BCM requirements
Set the BCM Local Gateway IP interface to the following using BCM Element Manager (go to
Configuration > Resources > Telephony Resources > {Select IP Trunk} > H323 Settings tab):
• Set Call Signaling to GatekeeperRouted or GatekeeperResolved.
• Set Primary Gatekeeper IP to the IP address of the NRS.
• Set Alias Names to the Alias name that was used when the H.323 Endpoint for the BCM was
created on the NRS.
In order to make a BCM 3.01 (or later)-to-CS 1000 call, ensure that the BCM routes and dialing
plan (used to reach the CS 1000 systems) match the numbering plan entry assigned to the CS 1000
systems through NRS Manager.
