Call Forwarding Services
It may also consist of an external number containing up to 18 digits,
including the network access prefix. This may be an external number
that is accessible through abbreviated dialling.
You may use fixed call forward defined by your system administrator.
This may consist of a call forward on no-answer condition, a call
forward on busy condition, or a call forward on no-answer and busy
conditions.
This fixed call forward is applied by default whenever you do not
define a variable call forward for your calls. This is often the case
when your facility uses an integrated voice mail service, which – by
default – receives your calls encountering a no-answer or busy
condition.
You may define all of the types of call forwards listed above, on
your own. This is referred to as a variable call forward that takes
precedence over a possible fixed call forward.
This variable call forward may be:
•
A pre-defined variable call forward assigned to the Call-Fwd key
on your extension. This is valid for all types of call forwards, except
call forward on mini-message. Simply pressing this Call-Fwd
key will either activate or de-activate the pre-defined variable
call forward.
• A variable call forward defined on a case by case basis. This is
valid for any type of call forward that is activated after it has been
defined. This then will take precedence over a call forward that
was pre-defined on the Call-Fwd key.
In any case, only one call forward applies at any given moment.
Defining a new variable call forward automatically cancels any
definition that previously existed.
A variable call forward is usually defined on a case by case basis
before you leave your extension. You may also remotely define your
call forward recipient from his/her internal extension. This is the
“Follow me” or “Third party call forward (or remote call forward)”
service.
The call forwards previously mentioned are those that are predefined.
Finally, your extension also offers you the call deflection service. This
is a call forward activated after a call is presented to you, on a call-
by-call basis, in cases where you would rather not answer that spe-
cific call, thus directing it to another recipient.
