Google believes it should be able to offer its product Google Voice without molestation by regulations that apply to traditional telephone companies, simply because Google is a free Internet application. AT & T certainly does not think so, and it seems that at least some congressional representatives agree. Especially those from rural districts.
Yesterday a group of House members from rural districts asked the Federal Communications Commission to investigate Google's practice of blocking calls to numbers using rural exchanges to charge inflated prices, something that the regulations prevent companies traditional telecommunications from doing.
Looks like Google may have to either bite the bullet and spend a bunch of money to change it's model, or spend money and fight regulators. Either way this could be interesting to watch to see if they are in this for the long haul.
