Abstract: The invention provides a call processing system to handle calls to a call center by obtaining absolute address for a call center resource from a call center resource processor prior to directing the call to the call center resource. The invention includes a call center resource processor that receives an address query from a communications system for an absolute address of a call center resource. The call center resource processor processes the address query to identify the absolute address. After identifying the absolute address, the call center resource processor generates an address response with the absolute address for the call center resource. The call center resource processor transmits the address response with the absolute address from the call center resource processor for the communications system to route the call using the absolute address.

Abstract: A prepaid service assurance system provides service assurance for a prepaid telecommunication system by generating a call to the prepaid telecommunication system. In response to the call, the prepaid service assurance system then receives an actual response from the prepaid telecommunication system and automatically compares the actual response with an expected response for the prepaid telecommunication system. In other embodiments, the prepaid service assurance system determines whether a modification action is needed based on the comparison of the actual response and the expected response. If the modification action is needed, the prepaid service assurance system identifies the modification action based on the determination that the modification is needed. Once the modification action is identified, the prepaid service assurance system transmits an instruction to provide the modification action for the prepaid telecommunication system.

Abstract: In a telecommunications network, a network host call server determines whether a call placed using a prepaid calling card was issued by a vendor other than the telecommunications carrier and if so, queries a database associated with the issuing vendor for information representing the telecommunications services associated with the card.
