This is HOT!
Excerpt:
The one big thing Google Voice doesn't offer, besides automated telemarketer
taunting, is free voice-over-internet phone calling through your cellphone.
On an Android phone, however, you can use the Gizmo5
service<
http://gizmo5.com/>,
Google Voice, and a free application to call anyone for free.
A free, open-source, and unofficial Android app,
Guava<
http://gizmo5.com/guava.html?loc=guava>,
gives any Android phone the ability to make and take calls over Gizmo5's
VoIP service, connected through a Google Voice phone number. It works over
Wi-Fi, 3G, or, for the daring, EDGE. You probably won't want to use Guava as
your primary phone call manager, as the call quality varies with your
connection and really works best over Wi-Fi. That said, if you're running up
against your minute allotment, or find yourself in a basement-like spot with
decent Wi-Fi but really bad cell coverage, Guava is a great little tool to
have at your disposal.
It's also worth noting that, depending on who your carrier is, making a VoIP
call over an EDGE or 3G network may violate your contract's terms of
service. A little "hard" data use now and then likely won't be noticed, but
if you plan on using Guava heavily with your cellular data plan, you should
check and read into what's tolerated and what's not before embarking on your
bold data-only adventure.
Mark, will you let us know how it goes?

This is a capacity and QoS issue on the other side. Get another app.
