4.5 AUTOMATIC
CALLBACK
If a called extension (in your exchange or in the private network) is busy or not
answering, you can request the system to callback automatically as soon as the exten-
sion will be free or when it has been used (in cases where no answer has been
obtained). You can have several callbacks activated at the same time.
Note that when you return to your office, by lifting and replacing the handset you will
inform the system that you are present at your office.
While waiting for an answer to call back you can make and receive calls as usual.
4.5.1 ORDERING
When the other party is busy or does not answer, do the following:
1)
Press the
Callback
(F1) key (the callback lamp is turned on). It can take a
couple of seconds before the procedure is performed and the lamp is lit.
2)
Replace the handset.
4.5.2 ANSWERING
Answer in the normal way within 8 seconds otherwise the Callback will be cancelled.
After answer the system will call the extension number on which you made the callback.
4.5.3
CANCELING A SINGLE CALLBACK
To cancel a single callback, do the following:
1)
Lift the handset (dial tone).
2)
Dial
#37* extension number#
.
3)
Replace the handset.
4.5.4 CANCELING
ALL
CALLBACKS
To cancel all callbacks, do the following:
1)
Lift the handset (dial tone).
2)
Dial
# 37 #
(the callback lamp is turned off).
3)
Replace the handset.
This procedure cancels callbacks to internal parties, busy extensions in private network
as well as callback to busy external lines.
4.6
AUTOMATIC CALLBACK IF ALL EXTERNAL LINES ARE
BUSY
You can initiate automatic callback, if you receive busy tone because all external lines
are busy. You can only have one callback on busy external line activated at the same
time.
While waiting for an answer to call back you can make and receive calls as usual.
