DT690
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 the 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.
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 an internal extension other than your DT690 that will be the recipient of
your call forwards. This is the Follow me service.
Note: When any type of call forward is defined on your extension, you still
94
have the option of placing calls and activating any type of service from
your extension.
When you have defined any type of call forward to an internal recipient,
the latter has the option of calling you without any restrictions.
When a call forward on busy condition is defined on your extension, no
more incoming calls will be presented to you when you have an ongoing
call. In the same way, the services of consulting and answering a new
call are deactivated.
For any call forward defined to be directed to an external recipient,
forwarding of calls issued from external parties may take place either
through your facility's resources or directly at the ISDN network level,
according to your facility's configuration.
You may program a call forward from your extension to itself. This
enables you to bypass any fixed call forward that is applicable to your
extension. Your extension is therefore available normally.
Serial call forwards between different users are authorized.
Your extension may also be subject to call forwarding from third party
sets. Certain extensions (such as yours) may possibly be equipped
with permanent protection against receiving call forwards from third
party sets. Obviously, this service will be denied on these extensions
(and vice versa).
