PCXSETAPPLICATION
This guide explains how to install and configure the pcXset software. It is
designed for resellers and technical support representatives. Only users
with administrative privileges can install and configure the software.
OverviewThe pcXset
user’s multimedia computer to have the same features and functions as
the NBX
Using the pcXset application is very similar to using the NBX Business
Telephone, except that the telephone has a handset, while the pcXset
software requires a headset with a microphone connected to the client
computer. You use the mouse and keyboard to operate the pcXset
controls.
The pcXset software can accept calls only when both the client computer
and the pcXset software are running. However, the software can receive
voice mail messages even if neither it nor the computer is running,
because voice mail operates on the Call Processor, not on the software.
The pcXset Help contains instructions for using the application. For
detailed instructions select Contents from the Help menu.
The NBX Business Telephone Guide has similar instructions, except for the
differences between using the controls of a physical telephone and the
controls of a software application.
