Ok, how many of you have gotten calls that were dialed by an automated system?
You know the kind. Your phone rings and if you pick it up there is a ‘pause’ before someone gets on the line.
Who then proceeds to tell you that,
”the FBI needs your information..”
“your car warranty is about to expire..”
“you owe money to such and such and we can reduce the amount…”
“we are in the neighbor hood doing x for the Jone’s etc.”

The list is just about endless.

Or how about getting messages on your voice mail or answering machine that tell you “to call 800-xxx-xxxx ext. xxx for a very important matter.” Or “you have an outstanding balance please call 800-xxx-xxxx etc.”

These calls and nearly all like them are made by ‘dialing programs’. There are two types most in use today.

The first and most common is the programs that actually dial a whole set of numbers for a given area code and prefix.
Example: 310-473-xxxx from 0001 on up.

The second is used mostly by fraudsters, bill collectors (illegitimate and some times legitimate) and other scammers.
The program dials a given set of numbers the same way.

HERE IS THE KICKER:
Since the calls are made by machine they follow rules! And we can exploit them to our advantage!
The programs were designed to save money by dialing fast and not wasting the time of (expensive) people. Although one could argue that wages in Bangladesh aren’t that high, you still need real people, even if they don’t speak proper English, to carry on a real conversation.
So when the dialer get’s an out of order or line disconnected ‘tone’ it marks the number as ‘no good’ and moves on.
If however you pick up the phone the system knows the number is valid and puts you through to a person who will then annoy the crap out of you.
Same goes for the calls on answering machines and those going to voice mail – if the dialer get’s an out of order or line disconnected ‘tone’ it marks the number as ‘no good’ and moves on. If your machine or voice mail answers with a ‘message’ like, “hello we are not here ……” the call then plays the message to call a certain 800 number back etc.
With any of these calls the absolute worst thing you can do is actually call that number!!
Your phone will be marked as ‘valid’ and ‘worth calling’ forever!
[This also applies to spam email too!! Never respond to spam email to ‘be removed from list..’]
So how do you we beat the machines?
Quite simple actually.
By playing the ‘call could not be complete’ or ‘number disconnected’ tone before your answer message.
That’s right by simply placing that ‘beep beep beep the number you are dialing…’ tone before your message you will kill the auto dialed call. If you are like me you can even play the tone before you answer a live call!
Just play the tone then record your message.
Make sure you tell people who should be calling you – family friends – that they should ingnore/wait for the actual message.

So where to find the ‘tone’.
Here are a couple links to the tones with the associated message.
Remember you only need the ‘tone’ at the beginning to make the dialer think the number is bad.
You can find them here:

I have created a looped tone with out the message that I use. It plays the ‘beep beep beep’ twice in a row. I will try and find a ‘place’ to put it when I can for easy download. Check back.
