Abstract: Systems and methods for call measurement services. The system includes a routing system, a client database, and a call block database. The routing system is configured to receiving an incoming call containing incoming call data which may include an original dialed number and a caller identifier. The client database stores at least one published number and at least one termination number, wherein each termination number corresponds to at least one published number. The call block database stores at least one blocked number. The routing system is operatively coupled to the client database and to the call block database and wherein the routing system is configured to route the incoming call to one of the termination numbers. Blocked numbers may be added to the call block database when telemarketing calling patterns are detected.
