Abstract
A voice call controller (VCC) polls session border controllers (SBCs) to determine routing of Voice over Internet Protocol (VoIP) calls and filter calls based on call source and originator parameters. The VCC re-routes calls in the event of errors, generates filters based on observed behaviors, and communicates filter rules or statistics to other entities.
Claims24
A method, comprising:
- receiving, by a voice call controller and from a call originator, a call, wherein the call originator and the voice call controller are located outside of a telephony network;
- determining, based on information indicative of prior call activity associated with the call originator, an average length of completed calls initiated by the call originator;
- and
- based on the determined average length of completed calls initiated by the call originator, performing one of blocking the call prior to the entry of the call to the telephony network or forwarding the call to a session border controller of the telephony network.
1 more element
A system, comprising:
- a telephony network comprising a session border controller, wherein the session border controller is located at an edge of the telephony network;
- and
- a voice call controller located outside of the telephony network and configured to:
- receive, from a call originator, a call, wherein the call originator is located outside of the telephony network;
- determine, based on information indicative of prior call activity associated with the call originator, an average length of completed calls initiated by the call originator;
- and
- based on the determined average length of completed calls initiated by the call originator, perform one of blocking the call prior to the entry of the call to the telephony network or forwarding the call to the session border controller.

A method, comprising:
- receiving, by a voice call controller and from a call originator, a call, wherein the call originator and the voice call controller are located outside of a telephony network;
- determining, based on information indicative of prior call activity associated with the call originator, a ratio of call attempts to completed calls by the call originator;
- and
- based on the determined ratio of call attempts to completed calls by the call originator, performing one of blocking the call prior to the entry of the call to the telephony network or forwarding the call to a session border controller of the telephony network.
