Abstract
Examples disclosed herein provide systems, methods, and software to validate calls to end telephone numbers. In one implementation, a method of operating a call state service includes obtaining and storing call state information for one or more communication in at least one data structure. The method further provides receiving a call state request for a communication of interest, wherein the request includes relevant call state information. The method also provides determining whether the relevant call state information matches a communication in the one or more communications based on the at least one data structure, and, if a match is identified, returning a call state match notification to the requesting end service.
