TeleVantage Server _______________________________________
The TeleVantage Server is the heart of the TeleVantage system. It controls phone traffic in and
out of your office, and maintains a database of user and system information, call history, and
contacts, as well as all voice files, including voice messages.
The TeleVantage Server runs on a Windows PC that contains Dialogic telephony resources. See
“TeleVantage Server PC requirements” on page 3-2 for specific Server requirements. See
Chapter 2 in Installing Dialogic Telephony Components for a comparison of the methods by
which you can provide telephony resources on the Server.
The Device Monitor
The Device Monitor lets you see the current activity and status of each trunk and station on the
TeleVantage Server. You can also start and stop the Server by using the Device Monitor, which
you can run independently of the TeleVantage Administrator application. The Device Monitor
is installed automatically on the TeleVantage Server PC.
The same information is also available in the Device Monitor view of the TeleVantage
Administrator.
Server reliability features
Because consistent phone service is vital to any business, the TeleVantage Server takes steps to
ensure continued phone service, even when the phone system is impaired.
Failover support
With analog phone service, TeleVantage ensures failover telephone support in the event of a
power failure or system crash. To set up failover, use the Dialogic DI0408LSAR2 integrated
trunk and station board, which supports on-board failover with direct trunk-to-station
connections (no cabling is required.) See “Supported integrated trunk and station board” in
Chapter 4 in Installing Dialogic Telephony Components for more information.
Note:
Failover support is only available for analog trunks. On systems that primarily use digital
(T1, E1, or IP) trunks, configure several analog trunks so that the system can automatically switch
to failover mode when necessary.
Other reliability features
For further reliability, Windows supports RAID drives and uninterruptible power supplies.
