At Google, we believe that our users should be able to export any data that they create in (or import into) one of our many products, and we've created a project called Google Takeout to make this process as easy as possible.
We're happy to announce that Google Voice is the latest product available for Google Takeout. This means that all of the data associated with your Google Voice account, from your call history to voicemail messages, greetings and call recordings, is now available for download. Voicemail messages and greetings are exported as mp3s, text messages as microformatted html, and forwarding phone numbers as a vcard.
