Abstract
Convenient and automatic methods are disclosed for reporting a violation of a do-not-call list. The only action required by the callee is to enter a predetermined touch tone pattern on their telephone key pad when they receive the call (e.g. pressing 999), and then hanging up. Network node(s) on the telephone network receive the touch tones and interpret the touch tone pattern as an indication of a violation of the do-not-call list. The network node stores the phone number of the caller, the callee number and the time of the call. The network node automatically generates and sends a notice of violation to the agency administering the do-not-call registry. In alternative embodiments, two network nodes may be involved in automatically generating and transmitting the notice of violation. The nodes may be nodes in a Signaling System 7 network.
