Abstract:
1. A method comprising: making a determination, at a call block system, whether a call block feature is enabled for a communication device based on a number of incoming calls from a particular calling device being less than a single-calling-party threshold and based on a total number of incoming calls being less than a multiple-calling-party threshold, wherein the single-calling-party threshold corresponds to a permitted number of incoming calls from one calling device, wherein the multiple-calling-party threshold corresponds to a permitted number of incoming calls from a plurality of calling parties, and wherein the single-calling-party threshold is distinct from the multiple-calling-party threshold; when the determination indicates the call block feature is disabled for the communication device, outputting a first dial tone from the call block system to the communication device; and when the determination indicates the call block feature is enabled for the communication device, outputting a second dial tone from the call block system to the communication device to indicate that the call block feature is enabled, wherein the second dial tone is audibly distinct from the first dial tone.
