It has nothing to do with that. The computer on the other end is just bulk dialing numbers from a given area code (aka robo call) and once it has exhausted the numbers from one area code, it moves on to the next. The plus is that VoIP allows the computer to dial thousands of numbers an hour. Then it just looks to see which ones score a hit, either by not doing a "This number is not in service" message with its tell tale three tone beep, or where the end user calls back to say they don't want to be bothered in the future which in turn verifies that the number is legit. At that point, the list is sold to fellow scammers to try and flood end users with calls for fake credit card/mortgage interest rate adjustments, etc.
