Hey, thanks for your feedback! Calloud supports phone numbers from way more countries than Google Voice does, plus we are focused on building an awesome product for businesses, there are many things that can be done on top of our service, and we can't wait to roll them out. Additionally, Google Voice is expected to integrate with Hangouts (they are probably focusing more on B2C), so it might lose some of its current functionality http://phandroid.com/2014/03/18/google-voice-hangouts-coming...
