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 call forward assigned to the Call-fwd (call forward)
key on your extension. This is valid for all types of call forwards,
except call forward on mini-message. Simply pressing this Call-
fwd (call forward) 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 defined on a case by case basis before
you leave your extension. If you forget to define the call forward,
you may ask the attendants to remotely define it for you. You may
also define your call forward from the internal extension (other than
an IP H.323) that will be the recipient of your call forwards. This is
the “Follow me” 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 specific call, thus directing it to another recipient.
