The quantity of hype and hoopla in the CTI market multiplies
at an exponential rate. The products that we at CTI magazine see in our labs are becoming better and better. The latest
products are solving real customer problems and saving corporations huge sums of money.
CTI products are the most profitable products for todays reseller.
Corporations installing CTI products find incredible productivity increases and can do
more with fewer people. SOHO users can have the image of a Fortune 500-class corporation
with call forwarding, conferencing, auto attendant, multiple mailboxes, and more for under
$1,000. From unified messaging to PC-based PBXs, computer-telephony integration will
change the way we all work. In a call center environment, CTI technology can cut agent
talk time down by 30 percent or greater.
In some call centers, CTI has a negligible effect on talk time but increases
sales by 30 percent. In other cases, customer satisfaction has jumped through the
implementation of call center CTI.
EVERY ROSE HAS ITS THORNS
As with any technology that receives a great deal of positive attention at first, there
are always a few negatives that rear their ugly head at a later date. CTI is no exception.
The effect of computerization has been dramatic in almost any industry you can
imagine. Fishing, farming, transportation, and believe it or not even
motion-sensitive lights benefit from the ubiquitous use of inexpensive microprocessor
control.
There is something special about CTI, however, that makes it necessary for those that
implement it to take special caution. I am referring to the letter "T," which
stands for telephony (or more generally, telecommunications). This single letter has
serious implications and whenever you see it, realize that a special term always precedes
it. That term is "mission critical." There is no situation in business where
your telephone system can undergo any type of interruption without the business either
looking unprofessional or losing money.
Packaging the mission-critical "T" for telephony with the surrounding letters
"C" and "I" means that the mission-critical nature of telephony must
be recognized and dealt with accordingly during its integration with a computer system.
This is true from the smallest home office, to the largest corporation, to the largest
call centers. If you are manufacturing, selling, or purchasing CTI systems, please make
sure that you account for the fact that computer platforms are not yet as reliable as
traditional PBXs or ACDs.
WHY THE PRECAUTIONS?
As any interconnect (PBX reseller) can tell you, PBXs are among the most reliable types of
electronic equipment on this planet. They just keep working year after year. Statistics
that I have seen place the average PBX downtime at around six seconds a year.
You dont need to have much experience in the computer field to realize that a
PCs downtime is much greater than six seconds per year. Although Microsoft Windows
NT is much more stable that Windows 95, it still cannot match the robustness of a PBX.
THE PBX: MORE RELIABLE THAN A PC
An important point to understand about a PBX is that it is a completely closed system. You
are not allowed to run any outside programs on a PBX at all. All programs that run on a
PBX are supplied by the manufacturer and are tested extensively for flawless operation.
Our own experience in the lab, however, has shown that we can force a PBX to do something
it wasnt supposed to. PBXs are far from foolproof; yet when they do make an error,
they dont seem to crash or lock up. Developers often tell me that many PBXs have
mechanisms built into them that allow them to perform a rapid software reboot without
disconnecting any lines. I wish my PC could do that.
Besides this inherent closed approach PBX vendors have taken, they have also
eliminated moving parts from the PBX entirely. An adjunct or integrated IVR, voice mail,
or auto attendant are the only exception to this rule, as they all need a hard disk to
operate.
Contrast this architecture to a PC server, where there is a constant flood of new
applications being installed: Web server software, e-mail servers, fax servers, file
servers, unified messaging servers, and many other applications that run on a server. The
temptation is always to run more and more of these applications on the same machine. Even
if youve gotten into the habit of purchasing unique machines for each server- based
application, there are lots of bells and whistles we load onto these servers out of
necessity or convenience anti-virus software, continuous disk defragmentation
software, backup software
the list is limitless. These programs often conflict or
cause instability in the entire operating system due to memory leaks and other problems.
ADVANTAGES OF THE PC OVER THE PBX
Economy of scale is the single largest weapon the PC has in its arsenal. Whereas most PBX
vendors have their own specifications for all of the internal equipment in their PBX, a
standard power supply from any computer can fit just about any computer. Likewise, memory,
graphics boards, keyboards, hard disks, and other peripherals are swappable between
machines.
This economy of scale has dramatic impact on the cost and construction of the most
stable and reliable PCs available. The industrial computer is the benefactor of a computer
industry based on component-level standards.
For a fraction of the cost and with the same functionality of a PBX, an industrial
computer offers redundant, hot swappable power supplies, error-correcting memory,
redundant processors, and RAID-based hard disks. In short, a PC or server that is based on
standard components can easily outperform a PBX on the basis of value when it comes to
fault resilience and fault tolerance.
It should come as no surprise that Microsoft Windows NT has become the runaway leader
in future CTI applications. Every vendor I have spoken to has an NT port in the works.
Customer demand seems to be the driving force. This demand will soon make NT the dominant
platform in this market, if it has not already achieved this goal.
Based on the points above, we know that CTI applications are only as reliable as the
underlying software of the OS and the application. Subsequently, it is safe to say that
the OS is the most important factor in the adoption of CTI, and that that OS will be
Windows NT. We have also established that as the operating system becomes more robust, the
CTI market will have fewer barriers to adoption. Every version of NT has become more
stable than the last, and we expect this trend to continue.
Although it is not a good idea to be the first person on the block to implement the
latest software version (regardless of the vendor), make sure to upgrade your OS on a
timely basis, while carefully scrutinizing the appropriate trade journals that cover
software bugs and glitches. With the OS taken care of, make sure you are using the best
and most reliable industrial computer you can afford. Many CTI vendors have already taken
this to heart and are working with industrial computer manufacturers to produce
industrial-strength CTI products right from the factory of the industrial computer
company.
ROAD TRIP: INDUSTRIAL COMPUTERS
On a recent road trip, I was able to visit a couple of industrial computer manufacturers,
and got a feel for how they operate and what strengths they provide their OEM partners.
Industrial Computer Source
One such company was Industrial Computer Source, a fast-growing company that has a
reputation for sending out thick product catalogues on a regular basis. If you read this
magazine or any other, chances are, you have seen one of their many catalogues.
As I toured their plant, I was amazed to see that they are much more than just a
catalogue house. They have OEM agreements with some of the largest CTI and Internet
telephony product manufacturers in the business. Although I am not allowed to disclose any
of their customers, suffice it to say they have many of the major players in the industry.
While touring their plant, I had the opportunity to look at their upcoming Pentium II
266 MHz computer running some benchmark programs. Although this is far from the in-depth
product analysis produced by our TMC Labs, I can tell you that this machine was amazingly
fast. One of the features Industrial Computer Source is particularly proud of is the fact
that they have mounted the Pentium II "brick" right on the motherboard as
opposed to the daughterboard mounting popular with some other vendors in the field. The
sheer weight of this "brick" makes it a major stress point on the
daughter-board, and can cause long-term warping of the plastic board which can potentially
interfere with the solder connections on the board. Please see the companys Web site
at www.indcompsrc.com for more information.
I-Bus
Another vendor that I was able to visit was I-Bus. Although I was not able to conduct an
extensive plant tour, I-Bus relayed to me that they have a very strong desire to work with
OEMs and to continue to play a role as a design and development partner in the assembly of
leading-edge industrial-strength PC solutions. Please visit www.ibus.com
for more information.
CTI vendors should all be actively pursuing relationships with industrial computer
vendors to assure that the systems they develop are as robust as possible. As the CTI
market is still in its infancy, it is important that customers have trouble free
experiences with the CTI products they purchase. We want to create a population of repeat
buyers.
As a VAR assembling custom IVR solutions, keep in mind that todays customer
installs are tomorrows references. A reference such as "The installed system is
state-of-the-art and we really love it when it runs," leaves a lot to be
desired. Make sure to use only the most reliable components in your installs.
As end users, make sure to impress upon vendors that it is important to you to have the
most reliable components possible in the products that you purchase. Dont purchase a
product based on price alone. Industrial computers do cost more, but they are well worth
the added security and fault tolerance they provide in your mission-critical telephony
applications.
There are two important points I hope you will take with you as a result of reading
this Outlook. The first is that an industrial strength or fault tolerant computer
with a good UPS and power conditioning system are a must-have for any CTI installation.
Secondly, resist the temptation to place additional burden on your CTI server by running
too many disparate and unnecessary software packages on this or any other mission-critical
computer. Following these important guidelines will ensure a CTI installation that will
cause minimal headaches and be as reliable as possible today and in the future.
