NBX DESKTOP
CALL ASSISTANT
General
Information
The NBX® Desktop Call Assistant (DCA) application works with two
components: the NBX Networked Telephony System and the NBX TAPI
Service Provider (NBXTSP) software that you install on your PC. In previous
releases of the NBX Networked Telephony System the DCA application
was called the NBX TAPI Dialer.
DCA monitors and controls one specified NBX telephone extension. Some
of its many features include dialing any internal or external phone
number, and answering and transferring calls.
Prerequisites for NBX Desktop Call Assistant are:
■ NBX R4.1.0 or later
■ NBXTSP R4.1.1 or later
To install DCA, you need this information:

NBX Desktop Call Assistant works with the NBX Unified Communications
software. If you are using NBX Unified Communications, 3Com
recommends that you use the same password for both Unified
Communications and NetSet.
