As it's an upcoming Lightning Deal for 11 AM PST I have no idea how much the
price will be but Amazon is usually pretty aggressive with these when on
sale. I got the OBi100 recently and it was a cinch to install with Google
Voice (now to be free through 2012). Currently working alongside my Ooma
and both are great VOIP alternatives. Nice that GV gives free calling to
Canada too which Ooma does not include.
