Voice mail is without question one of the most
significant communication technologies of the past
decade. It enabled business people -- and ultimately
consumers -- to access messages from virtually any
location where a telephone was present. And like any "killer
app," its rise in popularity created significant
advantages for users, however it also created several
dilemmas: How to manage messages based on the amount of
time a user has at any given moment, and which messages
are the most critical at that time.
In fact, a recent study published in The Wall Street
Journal proclaimed that working professionals handle
more than 200 incoming and outgoing messages of all
types per day. Considering the amount of time it takes
to retrieve these voice mails, in addition to e-mail,
faxes, and instant messages -- let alone analyzing the
content and responding -- there is clearly a need for a
solution that consolidates all of this information so
that knowledge workers can manage it more efficiently.
Unified messaging builds on the proven functionality
and value of voice mail by integrating it with other
messaging channels that include e-mail and fax in a
single mailbox that offers expanded message and contact
management capabilities. By implementing a unified
messaging solution, users have the ability to access,
manage, and reply to all messages from a PC, touch-tone
telephone (wireline or wireless), or PDA from virtually
anywhere in the world.
Unified messaging has proven to be a powerful tool in
helping knowledge workers organize and manage not only
voice mail, but also other non-real time communications
such as e-mail and fax. Currently, enterprise
communication providers are working toward complementing
the functionality of unified messaging solutions with
technologies such as collaboration, personal assistant,
and mobility applications to create a unified
communication experience.
Unified messaging and unified communication are an
outgrowth of the success of voice mail, which continues
to enjoy a must-have status in today's business
environment. As companies' needs evolve and change,
these real-time, near-real-time, and non-real-time
elements will form powerful building blocks for the
execution of unified communication strategies.
Enterprises must design communication to fit their
business models and balance the need for standards-based
software and IP-enabled hardware with their need to
maximize return on investments and minimize disruption
and risk.
Making The Case To Unify
Workers can spend up to 58 percent (approximately four
hours) of their workday away from their desks. In other
words, they are away from their traditional offices,
unable to take calls, check voice mail, or read e-mail
for a block of time that would take up the entire
morning and the lunch hour of the workday. These numbers
can increase exponentially when applied to executives
and salespeople, who typically spend most of their time
on the road. Being out of touch can mean risking
relationships that are increasingly essential in today's
customer-centric economy.
To remain competitive, an enterprise must constantly
improve its communication abilities by enhancing
communication tools for its workforce, customers, and
partners. Efficient communication drives customer
responsiveness and advances employee productivity. This
results in increased satisfaction, retention, and
loyalty for both customers and employees.
Taking Step One
To date, accessibility to multiple applications beyond
messaging has been the barrier to realizing the full
benefits of unified communication. Portal technologies,
however, have the potential to change that by enabling "anytime,
anywhere" access to not only messaging applications, but
also additional communications functions and
collaboration technologies, creating true unified
communication.
Imagine this business scenario: A global customer
accesses a Web site and clicks to send e-mail to the
sales department with a question on a pending contract,
which is included as an attachment. The salesperson is
on the road and is notified on her cell phone -- her "Communication
Enabled Portal" -- of the urgent message. Using
text-to-speech capabilities, she listens to the customer's
e-mail. The question requires help from a business
partner and product manager in two other locations --
and help from her assistant who works from home.
Switching over to the "Multimedia Collaboration"
function on the portal, the sales person uses voice
dialing to dynamically set up an audio conference call
with all parties to collaborate on the response. The
business partner provides the information needed and
drops off the call. The sales rep's assistant shares and
edits the document with the product manager in real-time
data collaboration session and then sends the revised
contract, along with a voice message, to the customer as
an e-mail attachment. The customer is very satisfied
with the rapid service received and the salesperson has
one less transaction to worry about when she arrives
back at the office.
Accessibility
Once a company puts its unified communication strategy
in place and begins to design and implement a "Communications
Enabled Portal" that meets its business needs, the
company can begin to realize the benefits of having a
single server-based or Web-based message box. This is
where voice mail continues to play a major role in a
unified network. Customers, partners, and employees
still need and choose to leave messages -- after all,
humans are not going to keep their devices turned on
24x7. However, unified communication enables the
receiver to react to any message at any time regardless
of format in which it was sent, including voice mail.
For example workers can:
- Respond to customers with speed, ensuring
excellent and consistent service. With the ability
to access and manage all messages seamlessly using
their choice of a PC, telephone, PDA, or Web
browser, employees save time, allowing them to be
more responsive to customers.
- Simplify collaboration for better, faster
decisions. Unified communications can speed response
time by enabling users to listen to e-mail messages
over the phone via text-to-speech conversion and
reply instantly, in turn enhancing the convenience
of checking e-mail by having it act more like a
traditional voice mail system.
- Send and receive fax messages with a PC,
streamlining processes and increasing accessibility.
- Generate voice mail messages as e-mail attachments
that can be sent to anyone with an Internet address,
enhancing the ability to communicate with
traditional e-mail-only users.
- Reply in the medium of choice, allowing users with
a preference for e-mail or voice mail to use the
application and device most comfortable or
convenient for them.
- Work with compound messages, such as forwarding
e-mail or fax messages with a voice introduction; or
embedding voice messages into e-mails, adding
personalization and emphasis to any message.
Put simply, unified communication enables
organizations to operate more efficiently no matter
where users access the system -- at their primary
office, at remote locations, or when they are mobile.
Choosing A Solution Today
One of the key strategies for implementing a
cost-effective unified communication system is
interoperability. A good unified communication platform
should integrate easily into the company's existing
infrastructure. For example, businesses that have made
significant investments in either their voice messaging
infrastructure or their collaborative environments
should identify a solution that can support it.
The right solution will provide scalable, open
systems architecture capable of supporting present and
future communications applications. Whether a company is
using a PBX or IP-based communications infrastructure, a
good unified communication solution should be capable of
extending an organization's reach and provide a new set
of tools designed to positively impact the bottom line.
When evaluating different solutions, look for ones that
offer a full range of dynamic options such as the
abilities to:
- Answer PBX-forwarded telephone calls and play a
personalized greeting;
- Forward or transfer calls or record the caller's
message and store it on the user's unified message
box;
- Detect fax calls and automatically transfer them
to a third-party fax server that places the document
in the user's unified message box; and
- Support both small and large sites through a
scalable architecture.
Positive Returns Tomorrow
Unified communication's potential return on investment
lies in its ability to support revenue growth and market
leadership. If Company A doesn't respond to inquiries
fast enough, the customer is a mouse click or phone call
away from doing business with Company B. Therefore,
handled separately, unanswered voice mail, e-mail, and
fax messages can present a liability. For example, what
good is a cell phone to a company representative on the
road when an urgent e-mail arrives from a high-priority
client? The short answer is that it isn't. However using
unified communication solutions, the same company
representative can listen to that message using a cell
phone and respond to it immediately anywhere, at
anytime.
This type of best-in-class service makes a strong
impression not only on customers, but the bottom line.
Businesses know now that it costs five to seven times
less to maintain a customer relationship than it does to
get a customer to come back. In addition, customers who
receive timely responses are more likely to remain
loyal, purchasing more and bringing repeat business in
the future. A good unified communication solution can
save 30 minutes of productive time per day, per
employee. For example in an enterprise where managers
earn $50K annually, directors $100K and executives
$200K, that translates into an annual savings of $3,125
per manager, $6,250 per director, and $12,500 per
executive.
Is unified messaging the end of voice mail? No. When
implemented in a scalable and interoperable solution,
unified messaging is a pliable technology with lasting
power that can provide a building block for future
unified communication capabilities. Combined unified
communication capability will heighten businesses'
ability to respond to customers with speed and quality.
It will also simplify collaboration for faster and
better decisions. Unified communication will help make
lives easier, more mobile, and more efficient, and when
the right solution is implemented, it can be done with
minimal risks and entry expense. In short, unified
communication will drive responsiveness, competitive
advantage, and productivity.

CTI: Strong Enough For
A Portal?
BY RON KENNEDY
Feature-rich CTI platforms are shaping up as a key
element to success in the unified messaging portal arena
today. Cost pressures and time-to-market needs have all but
ruled out deployment of alternative PBX type systems as a
viable option. Such legacy platforms offer all the resources
needed to support thousands of simultaneous users. The
addition of new applications or features, however, can be a
timely and cost prohibitive exercise. Service
differentiation and competitive pricing models are therefore
both difficult to implement within these environments.
The Scalability Question
One central question to answer over the coming months,
however, is this: Can traditional CTI (computer-telephony
integration) architectures deliver enough scalability and
system flexibility to handle the peak demand cycles of an
ASP (application service provider)? How this scalability
issue is addressed will likely go far in determining some of
the winners and losers in emerging unified messaging portal
markets. Traditional CTI systems have long delivered
improved customer service and the more efficient use of
resources within CPE environments. The emerging unified
messaging paradigm, however, places a whole new set of
requirements on hardware and software used to build new
applications as well as deliver services.
Personal unified messaging portals provide a
standards-based e-communication system that offers a
seamless interface to individual contacts, information, or
programs as well as all the intelligence and integration
necessary to make Microsoft's .net computing paradigm a
reality today. To support this new environment, CTI
platforms will need to break with the bounds of traditional
thinking. The goal must be to move towards a next-generation
architecture with independently scalable subsystems capable
of easily and seamlessly getting onboard the IP power curve.
Real-time voice processing operating systems (VPOS) form
the core of these next-generation architectures. These
operating systems allow independently developed applications
to run on the same DSP. The combination of applications
loaded onto each DSP can be determined at run time rather
than being statically configured, and is limited only by
available real time and memory. VPOSs can also dynamically
allocate each instance of an application to one of up to 256
voice channels and more, depending on the needs of the
application developer and service provider.
These capabilities open up some intriguing prospects for
scaling CTI platforms to meet the needs of unified messaging
portal providers. Constantly shifting user demands, for
example, can be easily met by adjusting how many instances
of the same application run across multiple voice channels
at any point in time. Rather than statically allocating a
certain number of channels to each application when the
system is initially configured, service providers can simply
use a GUI front end to deliver more channels for one
application over another. Since the VPOS is able to load
only those applications needed at any point in time, new
services or features can be added without the need for
additional hardware. Service providers can do more with less
expense and complexity.
The need to support additional voice channels within this
architecture can be easily handled by adding more DSPs
rather than extra resource cards. Since most chassis can
support only a limited number of resource cards, system-wide
channel densities can therefore be increased at a
substantial cost advantage.
Allocation Without The Crystal Ball
Next-generation CTI architectures essentially do away with
the need to statically allocate CPU resources, voice
processing capabilities, and individual ports to each and
every CTI application. Such traffic engineering calculations
were essential just a few short years ago. Service providers
that wanted to deploy CTI would need to first gaze into
their mystical crystal ball. They could then arrive at a
complex series of "best guess" estimates as to how many
customers would need what kind of access to how many
applications at any given point in the day. These numbers
would then allow engineers to bang resources into each and
every card. Changes in demand for one application over
another, of course, threw this entire cumbersome
architecture off balance. This makes it totally unsuitable
for the hosted application service model.
Optimized CTI systems today deliver full flexibility at a
multi-chassis level to shift and share resources on-the-fly.
For hosted ASPs, this means that CTI systems within large
centers can be designed to scale in all dimensions of an
application over multiple hardware platforms. The same
system within smaller centers can also be collapsed into a
single chassis, with all the same feature rich suite of
services and scalability potential.
System-wide resources from an application standpoint
within this architecture appear almost as a virtual hardware
and software pool running across multiple CTI chassis. Where
this reaches its true industry standard potential is with
the emergence of a specification called Compact Packet
Switched Backplane (cPSB). This new telecom bus architecture
basically maps existing switched Ethernet/IP networks
directly onto the backplane of each CTI chassis. An
end-to-end IP architecture offers significant cost and
system integration advantages over other technologies like
ATM for an inter-chassis connect schemes. Standards such as
RSVP and MPLS both offer a way to achieve this. Both
standards have attracted substantial industry resources,
time and effort over the past several years.
Telephony systems -- that are increasingly more
dependable, smaller, and cheaper to own and use -- will
quickly become an industry imperative for most unified
messaging portal providers. cPSB architectures should be
able to meet these requirements by facilitating the optimal
pooling and sharing of DSP resources and physical ports.
Get On The Bus
In general, the adoption of IP as a ubiquitous bus
technology will go a long way toward easing many of the
system bottlenecks that currently hinder the widespread
deployment of CTI platforms outside of CPE environments.
Next-generation chipsets will emerge to fully exploit the
new bus architectures. Developers in the interim should look
to architectures that use today's more powerful switching
silicon. These chips can help minimize bottlenecks that may
exist in local-to-local and local-to-CT Bus switching. Most
importantly, systems should be built from the ground up to
support highly robust DSP resource pooling and flexible
allocation of resources. This will allow the development of
CTI systems that combine all the best elements of today's
LAN power curve with the scalability of the most ubiquitous
router network into a single IP-based architecture.
