Abstract
Now that IP PBXs represent the greater portion of lines shipped, equipment
providers are searching for ways to stimulate adoption across a broader range
of large enterprises, as well as smaller businesses that don't have the same
depth in IT resources. This report examines various factors that will
encourage the wider spread of VoIP which, in the process, will change the way
people communicate. However, bringing voice, data, and even video together
within what appears to the user as a single system - while adding wireless
capabilities - also represents a significant threat to traditional IP PBX
revenue streams. The report discusses the relationship between IP PBX players
and Microsoft, whose participation is essential for bringing the vision of
Unified Communications to the desktop.
The analysis also looks at the role of mobile carriers and their emerging dual
mode phones as IP PBX players attempt to take the wireless office beyond its
current niches. Finally, market shares associated with key PBX players, along
with a view of how shares vary on a regional basis, are also included, as well
as a five-year forecast for both traditional and IP PBXs by both line
shipments and revenues.
