The new hangouts app with Google Voice integration got downloaded by my phone. I turned it on to see what's up. I have "Send SMS From" set to "Reply from last number used with contact". However, when I look at the text entry box it says "Send SMS to XXX from my Carrier number", not "Send SMS from my Google Voice number", even though I have always used GV to send and receive SMS to that contact. What number will be used if I reply to this SMS thread, my GV number or carrier number? Does the Hangouts/GV integration actually work, or does this apparently erroneous notice say that it doesn't?
