Phone Toggle for Google Voice

Phone Toggle for Google Voice will automatically switch the Google Voice phone that rings when you enter or leave WiFi range.

Together with a Google Voice VoIP app, this allows you to receive calls for free when you've got a good WiFi connection and then use your carrier's minutes when you're out and about!

Phone Toggle is not a Voice Over IP (VoIP) solution; it should be used in conjunction with one. See apps like Spare Phone, Groove IP, Talkatone, etc. The role of this app, Phone Toggle, is quite simple, but crucial! Auto switching makes VoIP work.

To save minutes, you need to take calls with a VoIP app on your phone (which are FREE), so you need your "WiFi Phone" to ring. But you want your "Cell Tower Phone" - your real phone - to ring when you’re not on WiFi. Phone Toggle will set which forwarding phone Google Voice rings for you automatically and seamlessly between the two. When you leave WiFi range, a small amount of mobile data (3G/4G) will be used to toggle the forwarding phones (~2 kB).

Note: Free VoIP calling from Google Voice (Google Chat / Gmail / Google Talk / GTalk) is provided by Google and is currently only available in the United States.

Features:
•Automatically switch the phone Google Voice will forward calls to between your cell phone number and your Google Chat phone (“WiFi phone”) based on WiFi connectivity.
•Optional WiFi network whitelist so you can toggle your WiFi phone on only when you are on a reliable WiFi network (pick from your saved networks/SSIDs).
•Manually toggle the forwarding phones for Google Voice yourself if needed. You can also completely disable the auto toggle if desired. You can also lock either “phone” from being auto toggled.
