The Federal Communications Commission wants to know why Google's Voice service blocks numbers, how it does it and why it thinks it's legally allowed to do so, according to Wired.
The investigation seems to have been triggered by a complaint from AT&T that blocking such numbers amounted to a violation of net neutrality and or common carrier rules. Google argues that Internet openness rules don't apply since Voice is an online service, and is thus neither an ISP nor a replacement for a phone. However, Google public policy head Richard Whitt admits that Google does indeed block calls to rural areas due to the "exorbitant" fees in these areas.
Google has until Oct. 28 to respond to the FCC's questions, notes USA Today.
