Callback Module Works (finally!) in Freepbx

I'm very lucky because I have unlimited international data on a grandfathered ATT plan. Now that VOIP over 3g has come of age (and I've finally managed to tweak my phone), I can now make many calls from abroad for free. Incidentally, for mega data users, look at iPhone trip which is $65 a week or $250 a month for 7 gigs of data per week anywhere in the world.

Turning to the general issue, however, the amount of data in a call back trigger over 3g is minimal. The real problem is that once you turn on iPhone or Android international data abroad, you could suck through 20 megabytes in five minutes on other things that download at the same time. Now that many of the roaming SIMs have some prepaid data functions, Voxalot's callback which gives you a simple menu (which you can save offline) may prove cheap for some users.

The Chinese dual SIM phones seem like a possibility for a callback triggering phone and a callback.
