AT&T 4.1 Telephone User Manual


 
To use a system calling feature, press [ # ] followed by its dial code.
(Instructions for using these features on standard phones are included in
Chapter 5, “Feature Reference.”)
Use the switchhook (or Recall or Flash button, if available) on a standard
phone to place calls on hold, transfer a call, or set up a conference call.
(For details, see "Using the Switchhook" later in this chapter, or “Hold,”
“Transfer,” and “Conference” in Chapter 5.)
Ringing Patterns
You can tell what kind of call you are receiving by the way your standard phone
rings:
An outside call will ring . . . ring . . . ring.
An intercom call will ring-ring . . . ring-ring . . . ring-ring.
A transferred call, or a call on hold that is ringing back, will
ring-ring-ring . . . ring-ring-ring . . . ring-ring-ring.
NOTE:
If you use the system with PBX or Centrex lines, the PBX/Centrex distinctive
ringing patterns are not passed to phones. Phones use the ringing patterns
described here instead.
Dial Tones
You will encounter two different dial tones when making calls:
Outside dial tone is generated by your local phone company and
indicates that you can make an outside call.
Intercom dial tone is generated by the system and indicates that you
can make an inside, or intercom, call.
To hear the difference between the two dial tones, lift the handset. The dial tone
you hear (assuming the phone has been changed to select intercom first, as
recommended in this guide) is an intercom dial tone. To hear outside dial tone,
press [
9
].
Using the Switchhook
Some of the call handling instructions in Chapter 5 direct you to “rapidly press
and release the switchhook.” Pressing the switchhook for 1/4 to 1 second
sends a signal over the line called a switchhook flash. However, do not press
the switchhook too quickly. If you press the switchhook and nothing happens,
try again and press it a little longer.
NOTE:
If your phone has a button labeled “Recall” or “Flash,” use that button instead of
pressing the switchhook. For more information, see “Recall” in Chapter 5.
