What would it cost to Wardial a whole area code with TextToSpeech + SpeechToText on twilio?
If you need 1 minute per number: ~10,000,000 minutes * 0.013 $/minute = $130,000
[2-9](?!11)[0-9]{2}
So there's only 7,200,000 numbers allowable within a singe NANP area code.
Just sayin'...
At that office, like every desk (many unoccupied) had a normal phone, with an extension #.
In one instance, a recruiter called and it was answered and he/she was told not interested. After that call, every phone on each of the row of desks started ringing one at a time.
After about 3 - 5 such ringings, someone picked up and told them to knock it off.
For one thing, I have no idea how they got my desk number (they knew my name), as that's supposed to be internal-only information, so that was an unpleasant surprise.
For another thing, I'm of that population that strongly prefers text-mode communication over phone calls.
So making an cold call to my work was a great way to get a "fuck off" and blacklist that recruiter. I wonder from what business culture they come from, and what their success rate with that method are, to make that approach seem viable.
