Cisco and ShoreTel score highest with end-users in new enterprise VoIP study by Infonetics

BOSTON, MA -- (MARKET WIRE) -- April 30, 2007 -- Adoption of voice over IP technology by North American organizations continues at a steady pace, tempered by the large installed base of legacy voice equipment, which will draw out the inevitable migration to VoIP for years to come, says Infonetics Research in a new study.

In the study, "User Plans for Voice over IP: North America 2007," Infonetics forecasts the percent of small organizations using VoIP to more than triple and the percent of medium and large organizations using VoIP to roughly double between 2006 and 2011.

The big story in the enterprise VoIP space these days is unified communications, or UC, which integrates multiple communication modes (deskphone, mobile phone, e-mail, chat, etc.) into a single communications experience. Companies are putting the foundation for UC in place, as illustrated by the top 2 VoIP applications deployed, directory and unified messaging, which together form the cornerstone of UC.

"For the first time, we studied end-user attitudes toward IP PBX vendors on a number of criteria, such as technology, ease of use, security, pricing, and others," said Matthias Machowinski, directing analyst at Infonetics Research. "Interestingly enough, the vendors with the highest scores overall were relative newcomers, like Cisco and ShoreTel, who jumped into the voice market with pure play VoIP products. Cisco rates highest on the technology front, and people like the ease of use and value of the ShoreTel systems."

Study Highlights

--  Avaya and Nortel are the most commonly used manufacturers of TDM PBXs,
    Cisco is the clear leader in VoIP products
--  Close to half of respondents aren't encrypting VoIP media or
    signaling, but those numbers drop to less than a quarter by 2009, as more
    respondents begin to use IPSec for encryption
--  Hybrid PBXs currently lead the list of installed IP PBXs, but the use
    of TDM PBX/KTS declines by half by 2009, and this slack will be picked up
    by pure IP PBXs
--  The average percent of total voice product expenditures that is spent
    by respondents on VoIP products -- IP PBXs, IP phones, etc. -- grows from
    41% in 2006 to 58% in 2008
--  The number-one reason given by organizations not deploying VoIP is
    that their existing phone systems already do what they need them to do
Infonetics conducted in-depth interviews with 240 small, medium, and large organizations that use VoIP products and/or services now or will by 2008. Most respondents use in-house VoIP, some use managed VoIP services, and others use a combination of the two.
