Fighting Back Against Ghost Calls

An anonymous reader writes "You're doing something interesting. The phone rings. You get up, pick up the phone, and hear only silence. It could be a slasher waiting outside your house, but it's probably an errant computer at a telemarketer. This article describes how some are fighting back by setting up websites to track the worst telemarketers by their caller ids. The article mentions whocalled.us (one of the funnier urls I've ever seen), 800notes.com and numberzoom.com . One intrepid guy is even writing a program to check these sites when the call comes in before ringing the phone."

    Next up, a phone that connects to the internet, checks the number, than picks up without ringing and starts playing a tape of you acting interrested in what the telemarketeer says only to hang up after an hour. Either that or pick up and hang up immediately so the line stays clear. Whatever costs the telemarketeer most. All without the phone ever bothering you ofcourse.

      This software already exists! It's a free open source application called Telecrapper 2000. It refers to a text file full of phone numbers deemed "annoying" by the user and checks caller ID when the phone rings. If the caller is on the list the Telecrapper jumps into action, playing WAV files and waiting for the person on the other end to pause before playing the next WAV. After a while Telecrapper resorts to a subset of WAV files and plays them randomly until the caller hangs up.

      I used to work for a call center (as the DBA who handled all of the data) and you are pretty much correct about how it works. We had 40-60 callers working per any given shift, and our dialers were capable of dialing out about 120 numbers at once. There was a percentage (known/calculated statistic for this call center) of no-answer and busy signals, so they tried to tune it to be as efficient as possible. What would happen would be the 60 callers would be at their stations, and the call center computer would dial out 120 numbers. The first one that connects gets sent to the first caller (their phone rings, they pick it up and their screen is updated with that person's information), and so forth. Once all of the callers were engaged, or if too many of the people being called answered their phones at once, they were immediately disconnected. They called these 'nuisance calls' and the number of them was kept track of every night. They had a goal to stay under, and they usually made it. (I don't recall what the goal was, but it was greater than 0)

      There are also two different types of dialing, one is usually called 'autodialing', where the caller is sitting there, looking at the information of the person they are about to call. They initiate the call, and are met with a standard result: Answer, no answer, busy, line dead, etc. This causes no nuisance calls, because the caller is only calling that one person.

      The other kind of dialer is a predictive dialer, which dials ahead, and can cause the nuisance calls mentioned above. This is the most efficient method from a call-center point of view, because they can get through many more numbers. Lines that are no-answers, and busy never make it to the callers, so their time is spent with live calls.
