Note: Personal abbreviated numbers accept values between 00
and 19. Common abbreviated numbers usually range from 200 to
xxx.
2. Press to make the call.
Note: An abbreviated number is generally complete, but may also be
incomplete, which means that you need to enter additional digits
to complete the number. One advantage of incomplete abbrevi-
ated numbers is that it allows you to access a series of numbers
using just one abbreviated number.
6.5 Temporary Call Protection
If you want to prevent any intervention during an ongoing call, you can
activate call protection. The call protection service can be activated only
for one call at a time.
To activate temporary call protection, do the following:
1. Press 74 to access the temporary call protection service.
2. Dial the desired number.
3. Press to make the call.
Note: Certain extensions may be equipped with permanent call protec-
tion. The above described service is therefore applied to all calls
that are placed, without requiring any particular action on your
part.
6.6 Call Substitution With Signature
You can place an external call in substitution or with signature. This
concerns the exceptional use of a third party set, to place an external
call, just as if you were using your own extension. The main advantage
of this feature is that the call is charged to your own extension. Another
advantage is that on the substituted third party set, you have all of your
extension's customary services, most especially dialing discriminations
relating to various external numbers applicable for your extension. This
service is valid on a call-by-call basis. It is automatically cancelled at the
end of each call processed using this service.
To activate the call in substitution, do the following:
1. Press 75 to access the call in substitution service.
2. Dial your own extension number.
