An indication of an outgoing call may be received at a call control unit communicatively coupled to, and/or resident within, a telephone. The indication may include identification information for the outgoing call. It may be determined whether additional information regarding a called party associated with the identification information exists, and if so, a first operation may be performed on the outgoing call responsively to the additional information, otherwise, a second operation may be performed on the outgoing call responsively to an absence of the additional information. The additional information may include a user-configurable list of desired called parties (e.g., a whitelist) and/or undesired called parties (e.g., a blacklist). The additional information may also include called party identification information and/or a spam score.
