I love Google Voice because I can call my daughter in Canada from my cell phone with no international fees (It does use cell airtime of course).
I forward my home phone to GV so I can get transcripts of left messages sent to my cell phone as soon as they are received. GV transcripts are about 80 percent accurate in my opinion, but I can always call GV and listen to my messages if I need clarification. I could set it up to forward calls directly to my cell phone, but I prefer just to let anyone calling me at home to leave a message.
And as soon as Google Voice allows porting, I'm gonna cancel my home service and use Google Voice as my home number!!! Yeah, $25 more in my pocket every month!!
I have never given my GV phone number out to anyone.
I don't need to with all the options I have listed above.
As far as invites go, when I asked for one from Google, it was only 2 or 3 days when they responded.
