Abstract
A telephone line management system in communication with a telephone line is provided. In one aspect, the system includes a caller ID module operatively coupled to the telephone line for receiving and displaying a name and a telephone number of a calling party associated with a received telephone call and a false special information tone (SIT) generator module operatively coupled to the telephone line for sending a false signal on a telephone line substantially similar to at least a first part of a SIT in response to an incoming telephone call. In another aspect, the system includes a caller ID module, a false SIT generator module, and a controller for determining when the name and telephone number of a calling party is displayed and when the false signal is operationally coupled to the telephone line. In other embodiments, the system may include an answering machine module or a telephone module.
