I know this isn’t really a technology strategy that will help you in the classroom, but sometimes a little tech at home is necessary. That mentioned, there’s been quite a bit of buzz going around about a free service that unmasked calls in which the caller has chosen to block their number. Not a bad little feature to have when the little jerks youngens decide to prank you at home.

The service is called trapcall and here is what lifehacker.com has to say about how it works. “TrapCall works like this: When you reject or miss a call, your phone forwards those calls to TrapCall’s toll free number (you have to follow TrapCall’s setup guide to do this). Once sent to TrapCall, the service works its magic on the missed call and then re-routes the call back to you, this time with the caller ID unblocked. If you reject the call a second time, it’ll go straight to your normal voicemail. On the caller’s end, all they hear during this whole process is ringing.”

Setting this up is free and requires no additional software, though ATT and T-Mobile are the only carriers supported as of now. I decided to set it up on my phone and suprisingly set up is dead simple. It sounds too good to be true, and for all we know it just might. The service could be gone tomorrow, but I figure I’ll use it while it’s around.

If you’re wanting more information, several sites have been covering the story. You can check it out at lifehacker and wired.
