> "Open source Google Voice"<p>Which voice library does it use? I see a lot of Twilio references in the code.<p>Beside that, the GitHub description reads "Open source Google Voice with Receptionist abilities, built on top of Twilio" - the last few words are missing in the HN title - and that makes it misleading. As the code contains no open source Google Voice library/etc. It's a showcase for Twilio API.
There's also OpenVBX <a href="http://www.openvbx.org/" rel="nofollow">http://www.openvbx.org/</a> that I have found very fun to use.
