Passive call blocking method and apparatus
View Patent ↗A process and apparatus to support passive call blocking, a call block that is performed in a manner that the caller does not recognize as a call block. When passive call blocking is utilized, blocked callers receive a passive response, such as a continuous telephone ring, instead of an error message or rejection notification. The caller is thus unaware or uncertain that they have been blocked. Blocked calls are determined by comparing caller identification information with a caller database.
1. An apparatus comprising:
a call manager configured to receive a call from a caller, and configured to identify the caller from caller identification associated with the call; and
a passive call block assistant configured to send a false ringing indication to a caller when the caller identification matches an entry in a caller database.
2. The apparatus of claim 1 , wherein the call manager is configured to match the caller identification with the entry in the caller database.
3. A method comprising:
receiving a call from a caller, the call including caller identification information;
sending a false ringing indication to the caller when the caller identification information matches an entry in a caller database.
