Last number redial
To redial the last number, click on the dial button (the handset symbol) in the app's dialer
screen to bring up the last number dialed. Click one more time to dial it.
Google Voice DOES NOT support 911 calls. Starting with software version 1.1.7, if you dial
911 in the phone's native dialer, the call will be routed to your mobile network
(NOT Google Voice) no matter how you have set up your Built-in dialer preference.
