VOICE CONFERENCING SYSTEM

4.1 Placing, Answering, and Ending Calls

To place a call from the Voice Conferencing System, either just
begin dialing directly from the keypad or press the ON/OFF key
before you dial. (The VCS goes off hook automatically when you
start dialing if you haven't already pressed the ON/OFF key.) The two LEDs
on the VCS's main module will turn from red to green, indicating that the
Voice Conferencing System is off hook.
If you press the ON/OFF key but don't hear a dial tone, make sure the
VCS's LEDs are lit. If they aren't, make sure the power-interface module
is securely plugged into a working outlet (check the outlet by plugging a
lamp into it if necessary). Whether or not the LEDs are lit, make sure the
modular cables are plugged securely into the main module, the power-
interface module, and a working wall jack (check the phone line with a
regular phone if necessary).
To answer a call, press the ON/OFF key and begin your conversation. The
LEDs will turn from solid red to solid green.
When you want to end the the call, press the ON/OFF key and your call
will be disconnected. The LEDs will turn from solid green back to solid red.

4.2 Generating a Switch-Hook Flash (Adding a Third Party to a Call)

To generate a 500-millisecond "switch-hook flash," press the FLASH
key while a call is active (that is, while all parties are on the line
rather than while there is a dial tone or while a phone is
ringing). A "switch-hook flash" simulates quickly pressing and releasing the
switch-hook on a handset phone, which (for 95% of business sites connected to
a PBX or directly to the phone system) puts the existing connection on hold
while you dial the number of another party you want to add to the call. When
you hear a dial tone, dial the desired number, then press the FLASH key
again to conference the calls together. The LEDs will temporarily turn from
green to red for the duration of the flash and then back to green.
If you get a busy signal, no answer, wrong number, or any other undesired
result, you can drop the line you just dialed by pressing FLASH again. If you
do reach the third party you wanted, you can talk to them for as long as you
like. When you conclude your business with the third party, hang up to
terminate the entire call, or press FLASH again to drop the third party's line
but continue talking to the second party.
