PictureTel LIVE GATEWAY 3.1 - Manual (Page 47)

Using PictureTel LiveGateway
Overview
With PictureTel LiveGateway installed on a server, LiveLAN and NetConference users and other H.323
terminals can place calls to H.320 clients and to other LiveLAN and NetConference users across an ISDN
WAN. LiveGateway is connected to the WAN by an internal ISDN BRI interface and to the LAN by the server
on which it resides.
By registering with LiveManager as a special terminal, LiveGateway lets H.323 clients access the WAN.
LiveGateway always uses the H.320 protocol in its connection to the WAN. It translates video, audio, and
shared application data from the H.323 protocol to the H.320 protocol.
This section describes how to place calls through LiveGateway and manage operator station information. It also
describes how to use the LiveGateway Audio Clip Recorder to record customized versions of the LiveGateway
automated attendant audio messages. The LiveGateway Audio Clip Recorder is automatically installed when
LiveGateway is installed on your server.
The information that describes how to use PictureTel LiveGateway is organized into the following categories.

Placing Calls through LiveGateway
With LiveGateway, LiveLAN clients and NetConference users can place calls to H.320 terminals and to other
LiveLAN clients over an ISDN WAN. The connection is transparent and gives users access to a larger
conferencing community.
Note: Since LiveManager cannot accurately detect if a LiveGateway’s ISDN line is active, it is
recommended that you disable any installed LiveGateways which do not have working ISDN lines, so
that other LiveGateways on the server, or on other servers, can be accessed.
Note: If you have problems placing a LiveGateway call in a system configuration utilizing two or more
LiveGateways, carefully review the data recorded in the
LiveGateway event log file . The information in
this log is helpful for both identifying and resolving issues such as an ISDN line that may be inactive
when it is not in use.
