Simple User Based Robo-Call Detection and Aversion

Implement a new standardized Vertical Service Code (eg. *69) that may be dialed either while off hook or after hanging up the phone. This service code would then be tracked in a database for frequency of use. A threshold for service code usage pertaining to any individual number would be needed that is high enough to assure that the caller is indeed robotic, and not accidental key-presses that might inadvertently disable or block valid businesses or individuals. This tracking system and automated database could then be used for further investigation and to issue citations to offending companies and advertisers. Such a solution wouldn't eliminate robotic calling altogether, but it could be used to severely minimize the number of affected users nationwide, and would employ the telephone user for screening and quality management services that they desire. To avoid confusion, legitimate call centers would be able to register their numbers to avoid potential outages caused by displeased call recipients. The same service could be offered by debt collection agencies as well, provided that they are not using a robotic calling system.
