I believe they are buying our mobile numbers so they can sell more of these 100's of caller ID apps / call your provider and they will trace all the numbers after one month , just don't be surprised if it is coming from one source but they use different exchanges etc. Hang time lasted 29 seconds this time!! OMG! I may activate call screening but that's likely what they are selling!

This is a rather long answer to some posters who seem to think the scammers use the DNC list to obtain numbers to call, or who think the DNC list does not work. If you are not one of those people, consider exiting this informative lesson now.

Since you are still here, you need some help. Allow me to present it in a very simple fashion ... not to insult your intelligence, but to attempt to get the idea across to even those who have difficulty understanding more complicated answers.

Can you count?
If you answered "yes", that is a good start. Try counting from 1 to 10 now. I will wait.
..........
Finished? Good.
I want you to think "0" instead of "10". Got it?
Now, get a piece of paper and a pen or pencil, and write down those 10 numbers. Here, I will help you, in case your forgot:
0 1 2 3 4 5 6 7 8 9
Now get ready to write down some more numbers. I want you to write them down in the following format:
ABC-DEF-GHIJ
Yes, I know those are letters, but I want you to use numbers, instead.
Think of a number between 0 and 9 ... pick one from the list I gave above, if you wish.
Write it down, instead of the "A", above
Do that nine more times, writing it down instead of the other letters.
Now, look at the result.
Does it ring a bell?
It should, because you just wrote down a phone number!
Mr Computer is very good at making numbers.
Mr Computer can do what you just did in a fraction of a second.
In other words, Mr Computer can make and dial phone numbers VERY quickly.
Spammers and scammers who know about Mr Computer do not need to register and buy the DNC list.
Spammers and scammers who know about Mr Computer can even dial "unlisted" numbers, or "private numbers" or "brand-new numbers you just got"!
The DNC list is not a magic switch that blocks these calls from reaching your phone. It is merely a list.
There, now you know all about how spammers can dial YOUR phone number, even if it is unlisted, and even if only relatives know it, and even if it is on or off the DNC list.
I hope that helps prove the DNC list DOES work! It helps prevent calls from registered / legitimate telemarketers, but it is not able to stop calls from telespammers. It is also NOT designed to stop political callers (who usually get the numbers from voter registration lists), calls from charities, or some other companies, such as debt collectors.
Again, I hope I did not insult your intelligence ... if you had any to insult.
