7-24
H.323 Endpoint Over an H.323 Backbone to H.323 Endpoint,
Using Profiles
In this method, endpoint details are transferred to the gateway using pre-
configured numbers. It is used when an local H.323 endpoint calls the remote
H.323 endpoint.
The H.323 endpoint connects using the following string: [ local GW prefix ,
first GW Link ID ] * [ Alias ], for example, 7011*1234

Step 1. The H.323 endpoint dials 7011*1234 representing the gateway prefix,
the Gateways Link ID, the Delimiter and Alias as shown in the above
example.
The digits 70 represent the local gateway prefix defined in the
Network Service Properties and 11 is the local Gateway Link ID
retrieved from the Gateway Link.
Step 2. The local gateway automatically dials the remote gateway using the
string 9042*1234. The digits 90 represent the remote gateway
(H.323) prefix taken from the local Gateway Link. The Remote
Gateway H.323 profile ID, 42, represents the configured Session
Profile (ID E.164) parameter defined in the
To H.323 Session Profile
Definition dialog box. The * is the Delimiter defined in the Gateway
