Since Google Voice is about letting you easily manage your communications, we wanted to give you various ways to organize your inbox. Besides the option to only display unread messages, you now have the ability to archive messages.
Archiving , a familiar feature for gmail users, moves a message (voicemail or SMS or recording) away from your inbox, but keeps it in your call history and the appropriate folder, so it remains accessible and searchable when you need it.
We hope you'll enjoy the new feature!
