Abstract
Methods, systems and apparatuses can be used to detect and prevent invalid or unwanted pulses. In various implementations, a series of dial pulses received from a telephony device can be counted to determine whether the series is valid. Based upon the count, a determination can be made whether the series of dial pulses is invalid.
