Free International Calls

Michael Gartenberg from Jupiter Research spotted this odd phone service for making free international calls, you call a number in Iowa (712-858-8883) and according to the site… “When the gateway answers, enter 011 then the country code and number you want to reach (mobile users, do not hit SEND - the call will go through on it’s own). Wait a few moments for your call to ring through and then enjoy your free call.”[via] - Link.

As Michael said, if there’s a catch, I can’t find one either (I called our MAKE Japan office, worked fine) - so, get your phone phreak on if you want to dabble and make some free international calls.

Here’s a how-to of sorts so you don’t need to pay for the Iowa call… use Skype to make a free local call to the Iowa # (in the USA calls are free within the USA) then just dial out internationally for free… Skype on a Mac sometimes has DTMF issues, but usually on a PC it works fine - try it out and post on up in the comments. I tried using Project Gizmo and it worked fine too…
