Even though AT&T may have had no part to play in Apple’s rejection of Google’s Google Voice app for iPhone, that doesn’t mean that the phone carrier is actually a Google Voice fan.
Apparently quite the opposite, the company has composed a letter and sent it to the FCC complaining about Google Voice’s blocking of certain telephone numbers which are operated by rural carriers, including those of the adult nature. As a common carrier AT&T is required to still put these calls through even though they would of course cost the company hundreds of millions of dollars each year.
AT&T argue the and one of the points they raise is that Google Voice is similar to a traditional phone service and should therefore play by the same rules. Google have been quick to respond to that point claiming that as Google Voice is a free application it is not required to follow carrier rules or listen to the FCC. Source – pcworld.com
