Abstract

Communications from a first communications address identified by a service user are controlled. Data of a communication from the first communications address to a third party communications address is received. The communication is disallowed when an identification number received from a party requesting the communication is not a personal identification number specified by the service user, the first communications address is a restricted address for which the service user has elected to disallow communications, and the third party communications address is not a priority communications address for which the service user has elected to allow communications.
