There's an update to Hangouts Dialer rolling today to make those Google VoIP calls a little more useful. The dialer's new trick is that it can handle phone call intents from the system. That makes it easier than ever to place calls through Hangouts with your Google Voice number.
After this update, you'll be able to select Hangouts Dialer as the default app for phone calls. Simply tap a phone number in a browser, Maps, or any other app, and you'll get that familiar "Complete action" dialog. You can select manually each time, or set either Hangouts or the regular phone app as your default.
As usual, we have an APK for you below just in case you want to install it a little early.
The APK is signed by Google and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for Google to push this download to your devices, which can take days, download and install it just like any other APK.
