Abstract
A signaling processor receives a first signaling message indicating a called telephone number for the call. The signaling processor processes the called telephone number from the first signaling message to determine if call validation is required. If the call validation is not required, then the signaling processor processes the called telephone number to determine routing information without the call validation. If the call validation is required, then the signaling processor determines if the call is valid, and if the call is valid, then the signaling processor processes the called telephone number to determine the routing information. The signaling processor transfers a second signaling message indicating the routing information for the call.
