Cisco reported that it sold 570,000 IP phones in its most recent quarter, indicating that corporations are finally buying into the whole VoIP thing and have moved past their early skepticism about technology. “VoIP is pretty much a foregone conclusion for next-generation corporate networks,” Craig Hinkley, senior vice president of network architecture at Bank of America told Computer World. “The discussion used to be ‘if VoIP,’ and it is now ‘when.’ ” But still, many are wondering when to implement the technology, since payback is not clear. CompTIA argues that it is a great productivity booster.
