Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

•Prefix 650 is added to gatekeeper localgk, and priority 0 is assigned to gateway gw1.

•A priority 0 is assigned to gateway gw1 to exclude it from the gateway pool for prefix 650. When gw2 registers with gatekeeper localgk, it is added to the gateway pool for each prefix as follows:

–For gateway pool for 415, gateway gw2 is set to priority 10.

–For gateway pool for 650, gateway gw2 is set to priority 5.

Configuring a Gatekeeper for Interaction with External Applications

There are two ways of configuring the gatekeeper for interaction with an external application. You can configure a port number where the gatekeeper listens for dynamic registrations from applications. Using this method, the application connects to the gatekeeper and specifies the trigger conditions in which it is interested.

The second method involves using the command-line interface to statically configure the information about the application and its trigger conditions, in which case the gatekeeper initiates a connection to the external application.

To configure a gatekeeper (sj.xyz.com) that uses port 20000 for a specific connection with an external server (Server-123), use the following commands beginning in global configuration mode. Server-123 has a number of triggers that are used to maintain a database of active gateways, which are used for active call resolution.

 

Command

Purpose

Step 1

 

 

Router(config)# gatekeeper

Enters gatekeeper configuration mode.

Step 2

 

 

Router(config)# server registration-port port-number

Establishes the server registration port that is used for

 

 

communication between the server and the

 

 

gatekeeper. The port-numberargument specifies a

 

 

single range of values from 1 through 65,535 for the

 

 

port number on which the gatekeeper listens for

 

 

external server connections.

 

 

 

Server-123 establishes a connection with gatekeeper sj.xyz.com on port 20000 and sends a REGISTER RRQ message to gatekeeper sj.xyz.com to express interest in all RRQs from voice gateways that support a technology prefix of 1# or 2#.

The following is an example of a registration message:

REGISTER RRQ

Version-id:1

From:Server-123

To:sj.xyz.com

Priority:2

Notification-Only:

Content-Length:29

t=voice-gateway p=1#

p=2#

When gatekeeper sj.xyz.com receives this message, the information supplied in the message is added to the trigger list. Then, when an endpoint registers with this gatekeeper by using an RRQ that matches the specified trigger condition in the message, the gatekeeper sends a notification to Server-123.
