Call Transfer
Call Transfer allows you to implicitly transfer an active call to a third party. You
need Flexible Calling enabled on your ISDN line.
■
To transfer an active call to a third party, and announce the call, press and
release the flash hook button on your telephone to put the active call on
hold and receive a dial tone. Then dial the third party’s phone number.
Announce the call and press and release the flash hook button to establish
a conference call. Hang-up the phone. The ISDN network will do an
implicit transfer to directly connect the two callers.
■
To transfer an active call to a third party, without announcing the call
(known as a blind transfer), press and release the flash hook button on
your telephone to put the active call on hold and receive a dial tone. Then
dial the third party’s phone number. Before the third party answers the
call, hang-up the phone. The ISDN network will do an implicit transfer to
directly connect the two callers.
Call Forwarding
The AR140 supports Call Forwarding. To use this feature, use the telephone
keypad to enter the appropriate dial access codes. Your ISDN service provider
will provide you with the access code. In most cases the call forwarding activa-
tion code is “*72” and the deactivation code is “*73”. While the Call Forward-
ing feature is active, the forwarded call is announced by a single ring on the
telephone from which you entered the access codes. This feature reminds you
that your calls are being forwarded.
■
To activate call forwarding, dial the activate access code (for instance
“*72”) and then the number you want incoming calls to be forwarded to.
■
To deactivate call forwarding, dial the deactivate access code (for instance
“*72”).
