Random digit dialing
Random digit dialing (RDD) is a method for selecting people for involvement in telephone
phone book. In populations where there is a high telephone
-ownership rate, it can be a cost efficient way to get complete coverage of a geographic area.
RDD is widely used for statistical surveys, including
experimental control groups.[2]
When the desired coverage area matches up closely enough with
VoIP
have begun to decrease the ability for RDD to target specific areas within a country and achieve complete coverage.
