Summary:A system to stop call looping in a communications network comprises a switch(12) to receive incoming calls, a server(14) operatively connected to the switch, and a call control function(18) 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.
