Google and Time Warner Telecom - VoIP Partners?

An anonymous reader wrote to mention a ZDNet blog entry by Garett Rogers, wondering aloud about the relationship between Google and Time Warner Telecom. From the entry: "It is rumored that Google has started testing 'Click-to-Call' which links potential buyers to advertisers via phone, but the third party who provides the communication services is still unknown. Could it be Time Warner Telecom who will be providing VoIP services for Google's Click-to-Call service?" We've previously mentioned the Click-to-Call service.
