looking for a free call android app?

[wyf]

Hi, has anybody ever seen something like this in android: an internet phone that can dial landline/mobile number in U.S. for FREE without limit, but at the beginning of each call I should listen an ads or two. Also it can dial other country's phone number for free but for a limited minutes for each call (of course I can accept no limit, LOL). If this app can accept inbound call (I have an U.S. phone number), it'll be perfect. Any response would be appreciated, thanks.
Thanks guys.
I've tried several GV related apps, but my ISP or something is blocking UDP port 5222, can't sign in, and I can't do anything about it. This is a problem for many people.
And I just tried Viber. "Viber out" is not free.
At first glance magicjack is perfect, but for unknown reason after 1 or 2 minute the call turns out silent, for both ways.
I mean, I can accept some ads, listen to some, watch some, but don't want to install app/game.
