  • System and method to stop call looping
    Patent number: 6845152
    Abstract: A system to stop call looping in a communications network comprises a switch to receive incoming calls, a server operatively connected to the switch, and a call control function running on the server. The call control function is programmed to determine if incoming calls, received at the switch and directed to a called number, are possible looped calls. If the call control function determines that a given incoming call is a possible looped call of a previous call, then it delays the forwarding of the incoming call to the called number.
