Chapter 3 Videoconferencing Basics
Before attempting a Gateway call, ask the system administrator to give you
the calling syntax. The syntax includes a service access number and, in some
cases, a variation of punctuation signs.

To call through a Gateway
1. Open the Manual Dial dialog (see "Starting a Videoconference from the
Manual Dialer" on page 2-7) and dial [service access number][ISDN
number(s)] in accordance with the system administrator's instructions.
2. Set the required Bandwidth or use the default bandwidth.
3. Press <Dial>.
The gateway's gatekeeper receives the call. It recognizes the syntax that
the system administrator instructed you to enter, and it passes the call onto
the Gateway. You must be registered with a Gatekeeper to reach a
Gateway (see "H.323 Network Registration and Properties" on page 4-5
for details).
The Gateway calls the destination, and when it receives an answer, it
begins the videoconference, continuously translating between H.320
(ISDN) and H.323 (IP).
