Call block
Call block
If you have subscribed to caller ID service, you can use the call block feature 
to reject certain calls automatically. The call block list stores up to 20 entries. 
The telephone system can reject calls automatically according to:
Numbers saved into the call block list
Incoming calls without numbers
This feature is only available on the telephone base.
When a call is blocked, the caller will hear a simulated 
busy tone for one ring cycle. The call recipient may pick up  
the call during the first ring when there is no caller ID  
information. Otherwise, the call is disconnected.
NOTE: The blocked calls are displayed as Blocked call in the caller ID log.
