Managing a telephone communication system to dynamically throttle call attempts and reduce congestions during mass call events

Abstract

A device is configured to detect congestion and throttle phone calls in a telephone communication system. The device is configure to receive, from a telephone dialing system, an indication indicating a call failure to a phone number; determine that the phone number matches a flooding group number based on initial digits of the phone number, the flooding group number associated with a flooding group, the flooding group including a plurality of phone numbers with initial digits having identical values to the flooding group number; determine a time of the call failure and a number of concurrent active calls for the flooding group at the time of the call failure; and in response to the number of concurrent active calls at the time of the call failure exceeding a predefined threshold, update a capacity limit for the flooding group based on the number of concurrent active calls.
