US Patent 9154597 No call list deterrent

Novel tools and techniques for deterring unsolicited calls are described for deterring unsolicited telephone calls that include a service provider searching and determining that the originating telephone number is in a no-call list, and based on this determination, prohibiting the call from terminating (i.e., connecting with the destination telephone number). Penalties may also be imposed against callers (e.g., solicitors) for no-call violations.
