The Network World story, "FAQ: How Google Voice could change the wireless industry," which ran on the wire on Thursday, incorrectly characterized the way the service works. The story has been corrected on the wire and the updated fourth paragraph follows:
No. When you make a call with Google Voice it initially goes through the standard public switch telephone network to the Google cloud. From there, Google sends the call to its final destination. This way, the person receiving your call sees it coming from your Google phone number rather than the one given by your wireless carrier. Additionally, Google Voice can use VoIP technology to route calls internationally and offer international rates that are vastly cheaper than those offered by major telcos.
