Call block
Call block settings
If you have subscribed to caller ID service, you can set the telephone to block
unknown calls and certain undesired calls. The call block list can store up to 20
entries.
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.
