Call Restrictor (Incoming) – Robinson Numbers
If there are certain persons who you absolutely do not want to call you, their external phone
numbers (Robinson numbers) can be assigned to a call restrictor for incoming calls in the PBX.
The call restrictor which applies to all subscribers can be enabled on your own telephone as
needed. If the call restrictor is enabled, a caller, who transmitted one of the Robinson numbers,
is rejected.
Call Waiting
If you are already in a call, the call waiting function notifies you using the call waiting tone when
another communication partner is calling.
Callback on Busy
After initiating a callback on busy (CCBS), a subscriber is automatically called back by the PBX
or by the central office when a busy subscriber becomes available again.
Callback on No Reply
After initiating a callback on no reply (CCNR), a subscriber is automatically called back by the
PBX or by the central office when a subscriber is reachable again.
Caller List
Telephone numbers of calls not accepted are saved in the caller list of the telephone, along with
the date and time of the call (for multiple call attempts, date/time of the last call attempt). A
maximum of 10 telephone numbers can be saved. If more than 10 calls from various telephone
numbers come in, the oldest entry is overwritten.
A caller be called back directly from the caller list.
The LED above the message key indicates whether entries are present on the caller list.
Calls
The system telephone allows you to make internal and external calls on the PBX. Internal calls
