The study was based on two online surveys of IT professionals conducted in December, 2004 and January, 2005. The first survey polled 106 respondents selected from Osterman's online panel of approximately 1,000 members, the second polled 103. All were at the manager or administrator level, or ''hands-on operations professionals below the CIO level'', said Michael Osterman, president of Osterman Research.
''Our study basically found two things,'' Osterman said. ''VoIP is definitely gaining traction in enterprise, and the primary reason is the perceived cost savings that comes from the technology.''
Roughly 60 of survey respondents said the most attractive thing about VoIP would be a reduction in telephony costs. They were also optimistic about the potential benefits of running all their videoconferencing, conference calls, e-mail, instant messaging, and Web access through a single Internet channel.
