Call Protection
Activating call protection also switches signalling of calls off for all
call numbers of your device (exception: VIP calls continue to be
signalled). When call protection is activated, a caller hears either a
ringing tone or a busy signal (the Forum 500 / Forum 5000 com-
munications system administrator configures this).
The administrator can configure a Call protection (see Program-
ming Function Keys starting on page 49). This involves defining
whether call protection applies to internal calls only, to external
calls only, or for both types of calls.
1. Press the Call protection function key to activate call
protection.
The softkey lights up red. The person calling hears the ringing
tone, but your telephone does not signal the call.
2. Press the function key once again to deactivate the call
protection function.
Tip: Call protection can also be set using the main menu:
5 Protection > 1 Call protect (see page 40). You can set the
type of call protection (internal, external, internal & external)
yourself in the main menu.
Note: Call protection is only in effect on the terminal where it was
activated. If the internal call number of the terminal is available
multiple times (i.e. on other terminals as well), call protection is
not automatically activated on them.
Call Waiting Protection
While you are making a call, and are thus busy, authorised inter-
nal subscribers can use call waiting to notify you that they are
calling you also. Activate call-waiting protection to prevent this.
The administrator of the Forum 500 / Forum 5000 communica-
tions system can configure a Call waiting protection function
