When the Voice over IP (VoIP) company Ooma started, it sold a VoIP home phone that enabled free unlimited calling.  But as it grew, it started charging a variety of monthly fees and taxes, although it grandfathered in people who bought the original product.My question is, are there any VoIP home phones that really do what Ooma started off doing, i.e. enable free unlimited calling with absolutely no monthly or annual fees or taxes?
