Supported Voice Features
A variety of supplementary voice features are described below. They
are for use by analog devices, such as a telephone or fax machine,
operating on your ISDN line through your ISDN TA.
Note: These features require that you have the proper ISDN service
established. For more information about your ISDN service, see the
chapter
“Ordering ISDN Service.”
Call Waiting
Call Waiting beeps when a second voice call is incoming while you are
on a voice call.
As with normal telephone call waiting, you can put the first call on hold
briefly and answer the second call by pressing the switch hook or the
“Flash” button on your telephone.
Call Forwarding
Call Forwarding allows you to route your calls to a different phone
number instead of your own.
When you order Call Forwarding, you are given three codes that
typically involve dialing “*” and then a two-digit number.
These codes allow you to set the telephone number to which you want
your calls forwarded, to turn the forwarding feature on, and to turn it
off. They are established by your phone company.
Caller ID
Your ISDN TA is capable of generating the signal necessary for Caller
ID. Thus, if you have Caller ID service established for your ISDN line,
your Caller ID box or Caller ID telephone will display the telephone
numbers that call you and the time that they call.
Message Waiting Indicator
If you have voice mail service for your phone line and you have
messages waiting, the “Alert” LED on your ISDN TA will blink green,
or the dial tone will stutter when you pick up the phone connected to
your ISDN TA.
The method used to notify you of waiting messages depends upon what
sort of equipment is used by your phone company.
Three-way Call Conferencing Options
This feature allows you to talk to two other people at the same time.
To use it, dial the first person as you would normally. Once connected
to that person, press the switch hook or the “Flash” button on your
telephone. Then dial the second person as you would normally.
Once you are connected to the second person, press the switch hook or
“Flash” button again. All three of you will now be on the line.
