During the call
Call Waiting (CW)
If a destination subscriber’s line is busy, this subscriber hears a call waiting signal as
soon as a second call comes in.
The destination subscriber can reject the waiting call. In this case, the calling
subscriber hears the busy tone. The other possibility is that the destination
subscriber accepts the waiting call, and the current call is placed on hold.
If analogue terminals are used, waiting calls are handled as follows:
Accept waiting call
Accept call waiting and terminate current conversation
Reject waiting call
Forward caller (without accepting)
Then enter target phone number.
If ISDN terminals are used, waiting calls are accepted or rejected via
corresponding menus. Please consult the User's Manual for your ISDN telephone.
Malicious Call Identification (MCID)
The MCID feature is used to identify malicious callers. The caller’s number is stored
in the operator’s network and notified on request. Call tracing is possible during an
active connection and within 20 sec thereafter. It is necessary to apply for the
enabling of this feature with the network operator. Charges are levied for the use of
this feature.
If ISDN telephones are connected, this feature is managed by the terminal itself.
For programming this feature at an ISDN terminal, please consult the User's
Manual for your ISDN telephone.
If analogue terminals are used, the feature can be enabled via the following key
sequences:
Trace subscriber
or
hang up
Requirement: The feature MCID must have been enabled by the network operator.
