NBX DESKTOP
CALL ASSISTANT

The NBX® Desktop Call Assistant™ (DCA) application works with the NBX
Networked Telephony System and the NBX TAPI Service Provider (NBXTSP)
to monitor and control one specified NBX telephone extension. Some of
its many features include dialing any internal or external phone number,
and answering and transferring calls.

To install DCA, you need this information:

■ Your telephone extension number

■ Your voice mailbox password

■ The IP address of the NBX system

When you install NBX Desktop Call Assistant on your computer, the
installation software checks for and, if necessary, installs a copy of the
Microsoft .NET Framework and the NBXTSP software If your NBXTSP
software is outdated, the program prompts you to uninstall the older
NBXTSP software and run the NBX Desktop Call Assistant installation
program again.
