NotBornYesterday writes "AT&T is accusing Google of being a hypocrite when it comes to Net neutrality because it blocks certain phone calls on its Google Voice service. 'By openly flaunting the call-blocking prohibition that applies to its competitors, Google is acting in a manner inconsistent with the spirit, if not the letter, of the FCC's fourth principle contained in its Internet Policy Statement,' Robert Quinn, AT&T's senior vice president focusing on federal regulation, said in a statement. Google blocks certain calls to avoid high costs due to a practice known as traffic pumping. Rural carriers can charge connection fees that are about 100 times higher than the rates that large local phone companies can charge. In traffic pumping, they share this revenue with adult chat services, conference-calling centers, party lines, and others that are able to attract lots of incoming phone calls to their networks. Google responded by saying that the rules AT&T refers to don't apply to Google Voice for several reasons. Google Voice is a software application that offers a service on top of the existing telco infrastructure, it is a free service, and it is not intended to be a replacement for traditional telephone service. In fact, the service requires that users have a landline phone or a wireless phone."
