Twiliobot allows adding voice capabilities to Google Wave by enabling Waves to interact with the telephone network. The Twiliobot demo allows adding a phone number to a Wave to enable calling. Twiliobot finds phone numbers in Waves and adds "Call" buttons to detect clicks and initiate calls. State is communicated through the App Engine datastore. The Twiliobot code is available on Google Code. Twilio is a cloud service that allows building voice communication apps through a simple API.
