I'm thinking of porting my landline number to AT&T prepaid phone and then to Google Voice. Then with my Obi202 device, I'll get new number (phone power service). I'll then setup call forwards in Google Voice from my old number to new number so this way all my friends/family will call old number and calls gets forwarded to new number. Even in future if i get new number, i can simply update forward settings in Google Voice. But now my question is, is it good idea to port number to Google voice? I really don't want to lose my number and I want to keep it for life. Any feedback greatly appreciated. Thanks
