Abstract:
1. A telecommunications signaling processing system for a call from a caller number to a called number comprising: a signaling interface configured to receive a signaling message; a validation table to determine if the call should be allowed based on whether the caller number is delinquent on payment; echo control to enable an echo canceller if the call is a voice call and to disable the echo canceller if the call is a data call; a POTs process to translate the called number to a route instruction if the called number is a POTS number; an N00 process to translate the called number to the route instruction if the called number is an N00 number; a VPN process to translate the called number to the route instruction if the caller number or the called number is a VPN number; a control interface to transfer a control instruction indicating the route instruction, wherein the route instruction comprises an identifier; wherein an interworking unit receives the route instruction, and in response, adds the identifier to headers of packets that will carry user communications for the call and transfers the packets to a communication system; and wherein the communication system routes the packets that carry the user communications for the call based on the identifier in the headers of the packets.
