I just tried to use hangouts with several of my contacts and it tells me that the other person is not on hangouts and only choice is to send an invitation.
I was having the same problem using the file that's available in the play store. Apparently there's a new version that's being slow rolled out that now includes the option for sms. The link is on the forums here. That's where I got it from. It will install over your current version and you should be all set.
