GVoice Callback captures outgoing calls and uses Google Voice to connect you, by calling you back at one of your verified numbers and, after you accept the callback, connecting you to the party originally dialed. This workflow is similar to Voice+ (no longer functional) or Google Voice's mobile web interface.

GVoice Callback is useful if you use Google Voice as your main number and a VoIP provider (e.g., FreedomPop, Talkatone, TextNow, Text Me, Sideline) that does not work with the official app (your carrier number will be displayed by default). It is also useful if your inbound calls are cheaper (or even free; e.g., Truphone) than outbound ones.

If you encounter any problems, please don't hesitate to contact me via email. You could also try requesting a callback on your DESKTOP browser: https://www.google.com/voice/b/0/redirection/voice, in order to rule out problems with VoIP setups (e.g., codecs, etc.).

Features:

(1) Call filter allows a single Java regex. Examples: To use GVoice Callback for international calls only, specify "^011.*"; for selected area codes: "^(321|456).*"; to exclude area codes: "^(?!321|456).*"

(2) Auto answer relies on several hacks, as Android does not provide direct support for it. Marshmallow and above requires Notification access.

(3) Call log integration: outgoing call preserved, incoming call from Google properly merged (if received by the system phone app).

(4) Toggle widget.
