Using Destinations
In this method, the destination endpoint number and the gateway session
configuration details are transferred to the gateway in the dialed number.
The H.323 endpoint connects using the following string: [ local GW prefix ,

Step 1. The H.323 endpoint dials 7011* representing the gateway prefix, the
Gateways Link ID and the Delimiter.
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.
In this method, endpoint details are transferred to the gateway which
includes a conversion table in which each E.164 ID number is
assigned a destination alias. Endpoint details are transferred to the
