System and methods for managing communications events

A method comprising:

• storing a plurality of unique associations between user accounts of users and VoIP telephone numbers;
• storing a cost of communications events for the user accounts;
• storing a revenue of presented advertisements associated with the user accounts;
• for each of the user accounts:
• generating a predicted cost of the communications events using a gamma-gamma cost model;
• generating a predicted revenue of the presented advertisements using a gamma-gamma revenue model;
• generating a margin based on the predicted cost and the predicted revenue;
• and
• when the margin for a given user account is below a margin threshold, restricting a status associated with the given user account.

A communications system comprising:

• a mobile network to provide mobile communications services for a plurality of mobile communications devices over a wide-area IP network;
• a wireless local-area network (WLAN) to provide wireless network communications services for a plurality of communications devices over the wide-area IP network;
• a Voice over Internet Protocol (VoIP) service coupled to the mobile network and the WLAN via the wide-area IP network to provide VoIP communications services for the plurality of communications devices;
• a public switched telephone network (PSTN) coupled to the VoIP service;
• a communications routing system coupled to the plurality of communications devices via the wide-area IP network to manage Voice over Internet Protocol (VoIP) communications events between a plurality of communications devices using respective VoIP telephone numbers;
• an account database storing a plurality of unique associations between user accounts of users and the VoIP telephone numbers;
• a cost database storing a cost of the communications events for the user accounts;
• a revenue database storing a revenue of presented advertisements associated with the user accounts;
• a prediction engine configured to, for each of the user accounts:
• generate a predicted cost of the communications events using a gamma-gamma cost model;
• generate a predicted revenue of the presented advertisements using a gamma-gamma revenue model;
• generate a margin based on the predicted cost and the predicted revenue;
• and
• when the margin for a given user account is below a margin threshold, restrict a status associated with the given user account.
