You can configure the prefix or suffix that is sent to the Gatekeeper.
The prefix identifies which Gateway is used to dial a call at a
particular data rate. The Gatekeeper then directs the call to the
Gateway that is identified with a prefix.
For example, the system inserts the prefix “90” before the number
when dialing a 256 Kbps Gateway call. The prefix tells the
Gatekeeper which Gateway to use to dial the 256 Kbps call.
To determine the appropriate codes for the call speeds, consult your
Gateway instruction manual. These codes are programmed into the
Gateway and Gatekeeper.
