Step 3. The remote gateway retrieves the endpoint Alias from the Address
Book table and connects the call.
H.320 Endpoint Over an H.323 Backbone to H.320 Endpoint,
Using Address Book
The H.320 endpoint connects using the following string: [ Dial-in No. ][ Link
DID ], for example, 43218071.

Step 1. The H.320 endpoint dials the MCU/gateway prefix and the local Link
DID. The digits 4321 represent the Dial-in number defined in the
Network Service Properties, 8071 is the Gateway Link DID taken
from the Gateway Link. The Gateway Link DID contains the Dial-in
number entered in the Network Service (ISDN).
Step 2. The local gateway automatically dials the remote gateway using the
string 90#42. 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.320 Session Profile Definition
dialog box. The # is the Speed Dial indicator (Address Book field)
defined in the
Gateway Configuration - General Settings dialog box.
The Address Book - Endpoint Definition dialog box contains the
Destination Identifier whose configuration is set to H.323 endpoint
