Routing Method - Address Book

When a call using the DID number reaches the gateway, the call will be
routed to the appropriate endpoint according to the endpoint IP address or
Alias defined in the Address Book. The session parameters are taken from the
Address Book and from the Session Profiles assigned to this Address Book
entity.
If one of the Routing Services methods is set to the Address Book, you need
to assign DID numbers to the entries to be called from an H.320 endpoint.
To define the properties of Address Book entries:
1. In the From H.320 Routing Services Definition dialog box, double-click
a Routing Service that uses the Address Book method.
