Google blocks calls to Benedictine nuns, doctors and schools, says AT&T

Mobile giant AT&T (T) has taken its ongoing battle with Google over net neutrality to a higher level. Literally. In the latest round of sniping between the two arch-enemies, AT&T has accused Google (GOOG) of using its voice web calling application to block phone calls to, wait for it, Benedictine nuns.

In a letter to the Federal Communications Commission sent Wednesday, AT&T contested Google's claim that the search giant blocks expensive numbers on its voice service that disproportionately are used by phone sex chat-lines. The letter comes after the FCC launched an investigation last Friday into Google's voice blocking.
