Call Protection

4.3 Rejecting a Waiting Call
GR0G …
While you are telephoning, the call-waiting signal tells you that there is a second
party wishing to speak to you. You can reject the waiting call, in which case the
caller will then hear a busy signal.
On ISDN telephones and on SIP terminals you reject a waiting call by means of the
corresponding function key or a menu.
4.4 Call Protection On/Off
For all (internal and external) calls
On:
H*42#
Off:
H#42#
Only for internal calls
On:
H*421#
Off: H#421#
Only for external calls
On:
H*422#
Off:
H#422#
You can protect your telephone against receiving internal and external calls
(except VIP and hunt group calls).
When configuring your user group, your system administrator sets whether a
caller hears a dial tone or an engaged tone when call protection is activated; ask
him for the setting which applies to you.
When call protection is activated, you hear the special dialling tone after lifting the
handset.
On a SIP terminal, you cannot activate/deactivate call protection with the code-
number procedure described here. You can, however, operate the feature with the
OpenCTI 50 additional programme. To do so, the system administrator has to
authorise you to use this programme. For more information, please refer to the
online help of the OpenCom 100.
