Abstract: A method may include determining that a digit pattern has been input on a user device to initiate a call; transmitting the digit pattern to a device that stores a list of digit patterns to which calls are not to be completed; receiving, from the device, data that indicates whether the digit pattern is on the list of digit patterns; prohibiting the call from being initiated with a network when the data indicates that the digit pattern is on the list of digit patterns; and initiating the call with the network when the data indicates that the digit pattern is not on the list of digit patterns.
