ABSTRACT:
Method and apparatus for detecting inter-carrier call looping. In one embodiment, the present invention is a method that can be used to reliably detect inter-network routing loops and kill associated calls using a modified ISUP Hop Counter parameter to be sent across network boundaries. Detection of inter-network loops prevents routing loops, those involving two or more carrier networks, from generating additional signaling traffic that can aggregate to overload signaling networks.
