Abstract
Selective filtering of an incoming telephone call is provided wherein a caller ID information of a third party wishing to converse with a first party already engaged in conversation with a second party is retrieved. The priority level associated with the third party is then determined and compared to a priority level associated with the second party. In the event that the third party has a higher priority level than the second party, the first party is alerted to the occurrence of the incoming call. Alternatively, if the third party has a lower priority level than the second party, the incoming call to an alternate destination.
