Callback on no answer
If a user does not respond when called, a caller can arrange an automatic callback.
As soon as the destination phone has completed a call and is free again the caller is
rung back. This service must be supported by the exchange. The callback request is
automatically cancelled after approximately 2 hours (depending on the telephone
exchange.
Caller identification
Displays caller's phone number, name or type of connection (e.g., exchange/
internal) on the telephone screen.
Caller list
Depending on the setting, the caller list contains callers you haven't reached, or
those you have spoken to. The last 20 missed calls and the last 20 answered calls are
stored with their phone number, date and time. If you wish, you can call back these
callers directly from the list.
Capture
Performance feature "Identify/capture". MCID stands for "Malicious Call
Identification". If you receive annoying calls, you can have the telephone exchange
store the caller number. This performance feature must be requested from the
network provider.
