To get a feel for the health of Internet telephony
as regards the enterprise market, we sent a short list
of questions to some of the leaders in that field. The
responses are presented below. In general, it can be
said with some confidence that the enterprise market
is healthy, due to any number of factors. The
increased reliability of VoIP equipment, the promise
of lower costs and increased efficiency, the gradual
fading away of the issues that stigmatized Internet
telephony (such as quality of service)... Couple that
with the fact that the current economic climate is
being viewed by some as a compelling reason to try
these promising new technologies, and all the signs
point in a positive direction.
Where once my inbox was filled to the point of
overflowing with announcements and press releases
introducing brand-new startups and heralding new
breakthroughs in technology, a quick perusal of the
e-mail I receive today finds a great many
announcements proclaiming partnerships, increased
sales, and other tales of technology deployment. There
may yet be technological issues that need to be ironed
out, but it appears that the increased focus on the
deployment of Internet telephony bodes well for the
industry as a whole.

The market for enterprise Internet telephony has
always been promising. If you went to an IP telephony
conference in 1998, you could hear presentations about
using the company Intranet to place branch office to
branch office phone calls or about using an IP PBX
replete with IP phones. You could even attend sessions
about using IP-enhanced and full IP call centers to
enable wonderful new applications never attempted
before. Come to think of it, if you go to an IP
telephony conference in 2001, you will probably hear
similar presentations.
But one thing is different today. There are now
actual installations and success stories for all of
these examples. From my perspective, the enterprise
market for IP telephony has always been less "forgiving"
in that this market demands the same level of
functionality and uptime as currently exists. Most
businesses cannot really experiment and deal with poor
voice quality, poor latency, or unreliable systems, so
most businesses have been reluctant to install
systems.
So as the IP telephony products improved with age,
the enterprise market was not forgotten and in fact
quietly thrived. Additionally, some businesses
experimented with dual systems to see if the IP
telephony promise of reduced total cost of ownership
could in fact be reached. And much was learned and
improved upon.
Today I see much promise in this market, and I
believe in 2002 we'll start to see a much higher level
of installations and success stories. I also believe
the economic downturn could in fact be a potential
bright spot -- businesses will be forced to "do things
differently" and this inflection point may cause even
more businesses to look toward IP telephony as the
solution.

Management, Intel's Telecommunications & Embedded

CISCO SYSTEMS
Over the past two years, Cisco has seen a steady
increase in both the number of customers who have
installed IP telephony solutions and the average
number of lines per site (phones) these customers are
purchasing. There are multiple contributing factors
that have led to these increases including: the
maturity of IP technologies and products; increased
deployment knowledge about channel and customer
solutions; an ever-increasing number of both
traditional PBX and IP-derived features; and
customer-driven initiatives for combining data and
voice together as one communication common strategy.
More than 250 of Cisco's largest 500
customers are implementing a Cisco telephony solution
with the Cisco Architecture for Voice, Video and
Integrated Data (AVVID) infrastructure as the
converged transport. Some of these customers include
The Dow Chemical Company, Merrill Lynch, the New
Zealand Ministry of Social Policy, NASA, and the
University of Arkansas at Pine Bluff.
Of most significance with these
customers is the growing understanding that voice
becomes a hosted application when deployed across IP.
A common transport can be leveraged and the same best
practices can be applied to any mission critical
application such as online transaction processing.
Many Cisco customers have realized that voice treated
in this manner offers cost savings with equipment and
administrative and network connectivity because these
best practices can be leveraged across multiple
similar application fronts. Additionally, customers
are beginning to marry data and voice together as
unified communication applications with the
consolidation of voice and e-mail store, one in-box
for reading messages, and Web-based driven rules
engines for customized call re-directing. These
applications are making employees more productive.
Regarding voice quality, a majority of
Cisco voice customers have implemented quality of
service policies and have experienced PBX voice
quality when handled across private WAN lines. While
the public Internet continues to hold promise for low
cost voice, quality remains a concern. As a result,
Internet-based voice connections are similar in
behavior to cell phone quality.

for Cisco's Voice, Video Business Unit.
MULTI-TECH SYSTEMS
Describe the general state of the enterprise
market for Internet telephony.
The enterprise telephony market needs to be
discussed in two sections: Branch or remote office
add-on equipment and enterprise-wide infrastructure
systems. The former represents products that work with
existing legacy routers and PBXs without expensive
hardware upgrades, and the latter represents extensive
systems
that often require equipment replacements and network
redesigns. With many of our enterprise customers the
first implementations of voice and fax over IP were
in remote and branch offices. Of particular interest
to multinational companies were the potential savings
associated with connecting such offices at
international locations. Remote and branch office
implementations that worked with legacy PBX and router
equipment tested the technical concept and proved the
savings
without undue costs in equipment. The second step, or "deployment
phase," of using branch or remote office equipment
throughout the enterprise network is proceeding
cautiously.
Have we moved beyond the "technology
phase" to a "deployment phase?" Are we seeing a
pick-up in the adoption rate of enterprise level
solutions?
We get the sense that the enterprise market
knows the value of VoIP from the experience of
implementing it in remote and branch offices both
domestically and internationally for toll bypass. We
see continuing interest in this level of equipment
from the enterprise as evidenced by an increase in the
number of vendors supplying such gear. So this level
is certainly moved somewhat beyond the technology
level into the implementation level. We believe the
deployment phase for this level of equipment will
continue well into the future regardless of how
large-scale deployment fares because of the large
amount of legacy PBX and router equipment that will
continue to need VoIP upgrading.
On the larger side of the business we
see spotty announcements of major companies adopting
the technology on an enterprise-wide scale, but we
suspect these are more attempts by the larger
suppliers to create an aura of interest than they are
evidence of wholesale implementation by large numbers
of companies. We believe that large scale deployment
is still in the technology phase and the jury is still
out as to when it will move to the implementation
phase.
How is the economy affecting the deployment
of Internet telephony solutions for the enterprise
market?
Certainly the downturn in the economy has hurt
the large-scale deployment of enterprise telephony,
but it also has spurred its deployment at the branch
office and remote office level. With a down economy it
is simple economics that implementing large scale VoIP
is too expensive while branch and remote office
deployment will save expenses without much risk. Keep
in mind that many of our customers use voice and fax
over IP implementation to solve a specific expense
problem area. By dropping in two VoIP boxes connected
to legacy router and PBX equipment costs will
immediately drop for both voice and fax
communications. That is a strong argument for the
technology in hard economic times.
What does the future hold for this market?
With the implementation of more sophisticated
IP gateways, gatekeepers and IP PBXs, we believe
telephony will evolve into a more IP oriented world.
In such an environment there could be an enterprise
level soft IP PBX where even the Central Office (CO)
is in a form not apparent today. Voice and fax calls
would be IP from one point to another with a CO-like
function in between that knows everything from TCP/IP
and H.323, to SIP, and MGCP and knows what to do with
it. IP enterprise telephony promises a universal
soft-IP network in the future. That means IP phones,
IP PBXs, and an IP network where the functions of the
CO and PBX are mixed in a "Centrex-type virtual
environment." With that kind of future promised by a
technology, which enterprises barely have started to
implement today, it is easy to appreciate why
decisions on implementing large scale VoIP are not
easy to make.

TEKELEC
Describe the general state of the enterprise market
for Internet telephony.
Many of the early adopters of Internet
telephony have been in the enterprise space. While we
don't have hard numbers to substantiate the
penetration, I think the success of companies like
Cisco and Clarent in selling media gateways and H.323
gateways indicates that there is a great deal of
activity in this space.
Have we moved beyond the "technology
phase" to a "deployment phase?" Are we seeing a
pick-up in the adoption rate of enterprise level
solutions?
I think companies have moved beyond technology
to deployment. We are beginning to see large-scale
implementations. Dow Chemical just announced that
in October of this year it will turn-up its converged
network to which 50,000 of its employees worldwide
will be connected. And, as we move toward pure packet,
end-to-end networks based on protocols like SIP, the
technology will become even more attractive for the
enterprise market.
How is the economy affecting the
deployment of Internet telephony solutions for the
enterprise market?
It's reducing the number of external options
available to the enterprise market. Before the
downturn in the economy, competition was fierce for
this business. CLECs were going head-to-head with
established carriers and competing by offering their
service at a substantially lower price. CLECs are now
struggling to survive and the pressure's off the
incumbents to lower prices or rush to create new
services.
This economy may very well increase
VoIP penetration into enterprise. Like most other
businesses, companies in this space are being pushed
to reduce costs. Enterprise businesses can leverage
their existing data networks by running voice over it
and reduce the external billed voice minutes from
external carriers.
What does the future hold for
this market?
I think we'll see VoIP take hold in the
enterprise space. Windows has announced that it will
support SIP on its 2000 and XP products. Microsoft's
NetMeeting already supports VoIP, but it's H.323-based
and doesn't support features like multi-leg calls and
caller ID. I believe that Windows support of SIP will
be a catalyst for the adoption of Internet telephony
in this space.

Telephony, Tekelec
INTECOM
Over the past several months, interest in Internet
telephony soared as companies began looking at the
cost savings offered by the technology. Voice over IP
and other voice/data services can be used to provide a
more cost effective, efficient, and flexible way to
build networks. The promise of VoIP may well signal
the future of networks. However, today there are
issues with quality of service that are still being
ironed out. In addition, large companies in particular
have huge investments in their current network
technology and moving to VoIP immediately would be an
expensive project. The result is that companies are
looking for ways to migrate toward VoIP while
protecting their investments as well as ensuring voice
and service issues. This has opened the door for a
phased approach to VoIP such as Intecom offers, which
allows enterprises to use their current networks while
adding VoIP at their own pace.
While the economy has forced some
companies to defer new investments, there is enormous
potential for companies offering a phased approach to
VoIP adoption. In addition, heavy merger and
acquisition activity creates the need for integration
of disparate systems. The migration of call centers to
contact centers that support other forms of customer
interaction (Web, chat, e-mail) in addition to voice
will also create increased demand.
And trends affecting certain
industries create new demands of customer service
levels that make reliable, scalable voice
infrastructure a must (for instance, utility
deregulation creates choice which creates new
requirements for expected levels of service to retain
or attract new customers.)

Product Management, Intecom
QUINTUM TECHNOLOGIES
Describe the general state of the enterprise market
for Internet telephony.
The enterprise market is getting stronger. I think a
lot has to do with the education of the market. There
has been quite a bit of experience with the technology
in the market. Enterprises now have a better
understanding of the "Risks and Rewards" of VoIP.
There has now been significant experience with the
technology, and enterprises are aware of the various
alternatives for addressing some of the issues that
have plagued VoIP -- such as QoS, ease of use and ease
of integration. Enterprises also have a better
understanding of the benefits of VoIP -- both in terms
of the immediate cost savings benefits and the longer
term need to migrate to a converged network to gain
competitive advantage.
The enterprise has a substantial
investment in its existing infrastructure and they
want solutions that both leverage that infrastructure
and support a migration to a converged future. They
are interested in building toward a convergence
future, but they do not want to restructure their
entire network to accomplish it, and they want their
systems to continue to meet the expectations of their
users. There are now intelligent VoIP solutions in the
market that address these concerns with unique
approaches -- it is not just about converting voice
into packets anymore.
Have we moved beyond the "technology
phase" to a "deployment phase?" Are we seeing a
pick-up in the adoption rate of enterprise level
solutions?
I think we are now moving into the deployment phase.
As mentioned above, many companies have experimented
with the technology and now understand how they can
best utilize the technology to save money and improve
productivity. Also, many of the companies that were
early to deploy the technology now provide excellent
case studies for those that have been considering
VoIP, but had been waiting until they had learned more
about the technology.
As vendors have better addressed the
implementation concerns regarding VoIP and
demonstrated successful installations, we have seen
not only more broad deployments, but more interest
from what one might call the more "conservative
enterprises." The interest in VoIP has certainly been
there, along with the concerns about the risks. There
are now more sophisticated VoIP systems that address
the concerns surrounding QoS, ease of use, and ease of
integration. Quintum products address the QoS concerns
by actively monitoring QoS characteristics and then
will transparently switch to the PSTN in the middle of
the call if the voice quality becomes threatened. This
system can be implemented so that users never know
they are even using VoIP. These types of solutions are
giving enterprises the confidence to deploy VoIP in
their networks.
How is the economy affecting the
deployment of Internet telephony solutions for the
enterprise market?
Our experience has been that the economy has actually
improved the market for VoIP. A year ago companies
were still very busy with Web-based projects, and
though there was a lot of interest in VoIP, it often
did not make it to the top of the priority list. Now
the Web projects have subsided, and the need to save
money and create more efficient infrastructure is
greater than ever! Not only are companies more
interested in VoIP technology, they have the time to
evaluate and deploy the technology.
What does the future hold for
this market?
I think the future IS all that has been expected from
the convergence market. The technology is becoming
more sophisticated and more accepted by CIOs. There is
a much better understanding about the potential that
can be realized through a converged network
infrastructure. Convergence makes too much sense not
to happen, though many enterprises will be looking at
migration approaches that allow them to leverage their
existing infrastructure. Enterprises now see the
vision of richer applications that integrate voice and
data together. While the market will continue to be
driven by the near term cost savings benefits,
enterprises also understand the benefits of
integrating voice into existing data and Web-based
applications, and they do not want to be behind the
curve in migrating to a converged network that will
support such applications.

of Marketing, Quintum Technologies.
