Chapter 1 - Executive Summary
Overview
This report examines the dramatic changes that are affecting the rich media conferencing
industry with a specific focus on the conferencing infrastructure market – audio, video, and
web conferencing servers and bridges, video gateways and gatekeepers and IM &
presence servers – the products that connect, service, and control users with conferencing
needs. Included in this report is an analysis of the current state of the market, a review of
the underlying technologies, background and analysis of over 35 vendors, current market
sizing and a 5-year forecast by product segment, results of an online survey from over 600
respondents, and comprehensive product matrices for each supplier across all product
types.

The rich media conferencing infrastructure market has experienced a tumultuous year.
While the market was still burdened by the telecom meltdown, general economic malaise,
and a lingering IT spending hangover, the first signs of market recovery have begun to
emerge. Forced with the need to raise productivity, users recognized rich media
conferencing as a viable alternative. Audio conferencing minutes and web conferencing
seats grew to record levels. Instant messaging became an accepted tool (if not officially
sanctioned) within many enterprises. Shipments of videoconferencing endpoints rose. All
of which signaled a rise in consumption was finally underway as measured in port or seat
shipments – though the upturn in terms of revenue dollars could have been stronger.

The rich media conferencing infrastructure market continues to evolve. While the past was
concerned with holding audio and video conferences over the PSTN with higher quality
and reliability, today’s situation is far more complex as the industry is being swept by three
fundamental changes:

1. As indicated by the number of IP ports shipped by the conferencing infrastructure
vendors in this report, the movement to a single, converged, IP-based voice-
video-data network is well underway. While the market was initially drawn to a
converged network on the promise to deliver higher quality and better reliability
with attractive economics, the prospect of using one network to seamlessly
integrate rich media conferencing into an enterprise’s IT environment may emerge
to be the real “killer app” of IP. The ability to initiate an instant rich-media
conference from within the very application that raises an issue or signals a need –
whether it be while reviewing a document, email, status report, or from within a
customer relationship management system, etc – could deliver the next wave of
productivity gains for an organization.

2. Web conferencing, instant messaging (IM), and presence have taken
conferencing-savvy organizations by storm. In addition to being IP-driven
conferencing tools, these three applications naturally play well together on a
converged network - IM is coupled with presence to show the availability status of
each potential attendee in real-time before a conference is initiated. While
conferencing has quickly transitioned from a scheduled to an ad-hoc paradigm
over the past few years, IM & presence holds the potential of taking ad-hoc
conferencing to a whole new level by bringing the first change to the call initiation
paradigm since the telephone was invented. And while IM text messaging has
been the traditional method of communicating using the presence metaphor,
advanced conferencing systems (Lotus, Microsoft, FVC, others) already integrate



the full spectrum of rich media conferencing tools so that an IM session can easily
escalate to include audio, video, or web conferencing. Because of the potential for
IM and presence to impact conferencing, we have added IM and presence servers
as a market segment to this report.

3. As if to underscore the potential of the above technologies, Microsoft and Oracle
have joined IBM / Lotus, the current market leader, in delivering rich media
conferencing as part of their enterprise software suits. Microsoft’s $200M
acquisition of PlaceWare and their establishment of an entire division dedicated to
real-time conferencing and collaboration has already resulted in the shipment of
the Microsoft Office Live Communication Server – covered in the IM and presence
server segment of this report. The entry of Microsoft into the rich media
conferencing market promises to take audio-video-web conferencing solutions into
the corporate mainstream, to increase general awareness, and to spur the entry of
multiple “partner” products; at the same time Microsoft’s entry is guaranteed to
change the competitive environment for all. The implications for the entire rich
media infrastructure market, including vendors of audio, video, and web
conferencing servers, cannot be understated – and are qualtified in the forecasts in
this report.

Wainhouse Research believes the conferencing infrastructure industry covers four different
elements, as shown in our diagram. Our coverage of the industry is contained in three
separate volumes: this volume which covers infrastructure products; a second volume that
covers video endpoints, and a third volume that covers conferencing service providers.

Methodology
Wainhouse Research monitors the entire rich media conferencing market through its
consulting, seminar/Summit, SpotCheck, and user activities, as well as by maintaining
continuous contacts with the vendor and end user communities. Part of the research in
support of this report included an on-line survey, details of which are included in an
appendix to this report. In order to assess the current state of the market and to ground
the forecast figures of this report in hard reality, we also interviewed and collected data
from over thirty suppliers.

Our data collection process maps supplier unit and revenue shipments into six product
categories:

1. Audio Bridges: Hardware multipoint control units that enable multipoint audio calls
over PSTN and IP networks.



2. Video MCUs: Stand-alone products that enable multipoint video calls over ISDN
and/or IP networks. We track both hardware MCUs and software MCUs for IP
conferencing in this category.

3. Video Gateways: Hardware-based products than enable H.320/ISDN callers to
connect to H.323/IP callers with a videoconferencing or data conferencing system.
This category does NOT include POTS-PSTN/IP gateways for the voice-over-IP
industry

4. IP Gatekeepers: Server products that perform the traditional H.323-defined
gatekeeper functions (explained elsewhere in this report) as well as an important,
emerging set of functions that bring videoconferencing closer to the world of
standard telephony –enhanced directory services, call forwarding functions, call
answering, etc.

5. Web Conferencing Servers: Server software and/or hardware that enables web-
based collaboration for data conferencing and remote presentations. This
category does not include web conferencing services which are covered in volume
3 of this report series.

6. IM & Presence Servers: Server software that provides an enterprise-class
“presence and availability engine” to support text-based messaging and other
forms of real-time conferencing.

Major Trends
Our forecast and supplier reviews note several trends that are shaping the future of the rich
media conferencing industry, and their impact on the market for infrastructure products:

Audio bridge manufacturers have completed the move to offering IP-friendly
architectures by adding support for IP voice in both all-IP and dual-mode products.
While the market for IP-based multipoint voice conferencing is materializing slower
than expected, WR believes the demand for IP ports from both enterprises and
service providers will fuel the market’s growth going forward.

The web conferencing server market will benefit from a shift to internal hosting from
web conference service providers as enterprise users seek more control, better
integration into their IT environments, and a perceived increase in security. This
trend is indicated by our user surveys.

Unlike audio, the shift from ISDN to IP ports for videoconferencing MCUs is well
underway with IP video ports outselling ISDN video ports on a ratio of about 6:1.
While IP video network services are being marketed by upstarts like GlowPoint,
Masergy, Internap, V-SPAN, IVCi, and others, their uptake has been slow. Thus
the majority of the demand for IP video ports is coming from enterprise users.

While demand for all forms of rich media conferencing ports and seats is generally
robust throughout the forecast period, the movement from PSTN to IP ports for
audio / video bridges and the commoditization of the web conferencing / IM feature
set works to lower prices on a per-user basis resulting in limited revenue growth.

Desktop videoconferencing may finally find its home as a feature that is added to IM
and web conferencing rather than being a stand-alone application, which will fuel



healthy growth in IP-based video infrastructure equipment (MCUs, gateways,
gatekeepers).

The need for stand-alone video gateways is quickly giving way in favor of mixed-
mode MCUs that can also handle the gateway function.

Rich media conferences will blur from being distinct audio, web, and video
conferences into one IP-based rich media conferencing entitly that will
accommodate endpoints with different audio, video, and data capabilities – and the
infrastructure that will tie it all together. IM and presence will be increasingly used
to initiate conferences of all types from within a growing number of applications.

The market sizing for 2003 indicates that demand for rich media conferencing
infrastructure products is growing and the economy is slowly improving. However,
the improvement is slower than expected and has caused the adoption of certain
segments of the market to be delayed by about a year compared to our previous
forecast.

Forecast Summary
Our overall results forecast that the conferencing infrastructure industry will grow from
about $475 million in 2003 to over $675 million in 2006, producing a compound annual
growth rate of 7.3%, despite dramatic declines in average selling prices across the board.

Figure 3 Changing shape of the conferencing infrastructure market

However, trends now underway in both the conferencing infrastructure market and the rich
media conferencing industry as a whole will continue to change the shape of the industry
over the forecast period. The market for web conferencing and IM / presence servers and
the market for audio conferencing servers will account for an increasing share of the
market – at the expense of the market share for video conferencing MCUs, gateways, and
gatekeepers.

It is interesting to note that our forecast grows at about 12.6% CAGR from 2003 to 2006,
then peaks and stagnates due to a number of factors explained in this report.

Forecast details including specific market segment sizes, growth rates, and significant
segment metrics where applicable (migration to IP, ports or seats, ASPs, enterprise vs
service provider revenues, etc) can be found in chapter 5 of this report.
