When you make a telephone call, the cost charged can be divided between different carriers involved in the completion of the call.
Settlement is the method used to divide the cost among carriers.
Traditionally, settlement agreements have been arranged between the carriers in a pairwise fashion. With the advance of voice and video conferencing over IP, pairwise settlement agreements have become cumbersome. A number of companies have entered the market offering settlement on a subscription basis. The Cisco gateway-based Settlement protocol interacts between carriers to create a single authentication at initialization. The authentication is the basis for the establishment of a secure communication channel between the Settlement system and the infrastructure component.
