Free Local and Long Distance Calling with netTALK’s DUO.

North America $70/year, International $120/year.  This seems like a Skype competitor.  It looks like there’s a piece of hardware that comes with this that can be seen here.

Here‘s how it works.  You don’t need a computer — just plug the device into the router and phone.  I noticed an HTC device trying to connect SIP to this outfit so they must have an Android app as well.
