Ten Reasons Why Your Company Should Switch to VoIP
Changing Direction of the Telephony Industry
Over the next few years, much of the $300 billion per year telecommunications
industry will migrate and convert its equipment and carrier services to
support packetized VoIP services on the WAN. It will not be long before traditional
telephony systems providers are outdated.
As older providers lose customer base and revenue, they will streamline
operations and eventually close their doors. The providers that stay in business
will need to increase prices and therefore become noncompetitive. VoIP
technology has become the strongest influence in the telecommunications
provider marketplace.
As VoIP emerges worldwide as the number one replacement for traditional
circuit-switched telephony infrastructure, manufacturers of telecommunications
gear will convert their product lines to meet customer demands for
VoIP-enabled systems. The same holds true for network services providers.
They will convert their core service offerings to give priority to VoIP-related
services. In fact, this is already occurring with most major carriers. The
demand for circuit-switched equipment and network services will decline. As
a result, the cost to suppliers who stay in the circuit-switched niche will go
up. These costs will need to be passed on to the customers.
The leading VoIP and carrier services companies have made a commitment
to developing secure and reliable IP telephony systems, communications
software applications, life-cycle services, and carrier provider services. For a
list of the leading manufacturers in the VoIP field. For a list of
the leading VoIP providers, see Appendix A.
In light of newer VoIP products and services, customers will want to convert
to VoIP so that they have adequate support available from outside companies.
Many companies will also want to develop the VoIP skills of their inhouse
personnel. In this way, companies can insure their long-term growth by
reducing costs and increasing revenue. VoIP can save companies lots of
money in operating expenses, but if you have a multilocation company, converting
to VoIP does require planning and VoIP skills.
Feature-Rich, Cost-Effective Alternatives
Most traditional telephony calling features have made their mark on the
industry. Features such as voice mail, call transfer, call forwarding, and threeway
calling have become familiar to all of us. The costs of these features are
either rolled into the cost of your company’s private telephony system, or
you pay for them à la carte.
All traditional telephony features as well as many new features and communications
applications are available in the brave new world of IP telephony. The
number of calling features is overwhelming. And they all come with no additional
cost because they are IP-based and are carried over the computer
network.
Simple features such as being able to look at your telephony station and see a
visual indicator that tells you whether someone in your calling group is “present”
but on the telephone at the moment can help increase employee productivity.
(Think how many times you wasted time calling people, only to get
a busy signal or their voice mail, not knowing whether they were at their desk
or not.) The presence feature is just one of many features available with VoIP.
Or how about the ability to run a soft phone on your computer and do telephony
using a point-and-click process with a headset? Such a capability
would never be contemplated in traditional telephony because that world
can’t support computer-related applications in a seamless manner. Many
other calling features are available in VoIP, all just as compelling to companies
considering a change.
Existing Investment Protection
If your company has a traditional telephone system (such as a PBX or KTS) in
place, you can protect your investment by adapting the system in the new
VoIP network. The PBX system probably includes many digital telephone stations.
These telephones can also be reused in the new VoIP environment.
Your company can migrate to VoIP while protecting your existing telephony
hardware investments.
A forklift upgrade is when you get rid of everything from the older system and
therefore lose your previous investment. The other approach is to use some
or all of your existing equipment. With the right VoIP partner, you can avoid
forklift upgrades to VoIP.
Seamless Maintenance and Management
The full benefits of VoIP are realized in a converged network — one in which
data and voice packets travel over the same infrastructure. Such a foundation
eradicates redundant information systems, so the major tasks of installing
and managing VoIP become more cohesive. Managers have more effective
and direct applications to support their many challenges. They can manage
not only computer data applications, but also IP-based telephony and videoconferencing
systems. Unified database applications running over the network
provide real-time, seamless access to all information needed to
maintain the VoIP network.
Moves, adds, and changes that would require complex and costly resources
in a traditional telephony network do not require the manager to do anything
in a VoIP network. Instead, the network automatically adjusts itself to accommodate
a user’s new location. Usage, accounting, and other metrics data are
available to the manager through any computer device attached to the network.
With VoIP, managing and maintaining the network becomes cost-effective
and seamless. Staff do not get caught up in problems and stay focused on
business deliverables.
Flexibility and Portability
IP telephony has spawned many applications that increase both the flexibility
and portability of communications. For instance, a soft phone provides
mobile employees with easy access to real-time communications and the
same calling features enjoyed by stationary employees. Users have never had
more telephone options available for mobility. Wireless extension to cellular
enables a “follow-me” feature so that employees can have calls ring at both
their office and their cellular telephones.
In a VoIP network, employees can travel to any of the company’s locations,
plug in their IP-enabled laptop, begin work, and make and receive telephone
calls. Employees have, at their distant temporary location, all the rich features
normally available to them at their home office location. The network
automatically identifies the user and applies that user’s profile information.
Employees can even direct their calls to any digital desktop telephone at the
temporary location. (The telephone does not even have to be IP-enabled.)
Managers no longer have to make costly and time-consuming accommodations
for computer data and telephony connections for a coworker visiting
their location.
Enhanced Network Management
VoIP provides a foundation for comprehensive network management. As a
result, the ability for you to manage every bit and byte that runs over your
LAN and WAN has never been more enabled.
Likewise, you have at your disposal tools that find and fix network issues so
quickly that managers may rarely know that anything has happened. These
types of tools can support local and remote network monitoring. In dedicated
networks, near-perfect quality is provided. That’s not to say that problems
never occur, but with a VoIP network, your ability to detect symptoms and
make changes to your setup in advance of any problems is greatly enhanced.
Better Utilization of Personnel
VoIP enables the realization of a converged network — data and telephony
traveling over the same network. Gone are the days when you needed two different
skill sets to maintain your networks (one for telephony and one for
data). Although there are some skills unique to VoIP that traditional network
engineers don’t have, the underlying skills related to Ethernet networks and
IP protocols are the same. This allows your company to maximize the training
of your people and, in many cases, reduce the number of personnel you
need in-house to support the network.
Productivity Applications
Many of the Web applications that previously ran exclusively over the
Internet will now run over your private VoIP-based communications network.
Your users can have their favorite Web page displayed on their VoIP telephone,
or they can post special Web links on their telephone-based Web
page. Many Web-based applications are candidates for running on your VoIP
telephones.
Users can also add a video telephony solution, powered by IP video application
software that enables a desktop PC or laptop to emulate an IP office
phone. The quality of the video and audio that runs on the company’s network,
versus the Internet, is free from latency and jitter.
Better Bandwidth Utilization
Many people wrongly assume that when you add VoIP to an enterprise computer
network, there won’t be enough bandwidth available to support the
change. The fact is that dedicated network transports supporting computer
data or traditional telephony systems are about 30 percent utilized. Even
though running both data and voice packets over the same network
increases overall traffic, you must look at how the IP-based traffic operates.
On the LAN side, fault isolation provided by switching equipment maintains a
steady mode of operation. If any chokepoints are identified, they can be
remedied almost immediately by changing connection points or doing what
the gurus call load balancing. But your IP-based management system will tell
you this before it even becomes a problem.
than one site on the WAN side that may have users connecting to your site. In
addition, the cost and overall bandwidth capacity of WAN transports are
higher and recur monthly when compared to the LAN side.
For example, a T1 line has 24 channels. If you run traditional circuit-switched
calls over the T1, you can maintain 24 simultaneous calls. The beauty of VoIP
is that it is packetized, so the same 24 calls could run through just a fraction
of the T1’s overall capacity. As a result, you gain multiple times the bandwidth
equivalent with VoIP when compared to circuit-switched telephony.
Reduced Costs
The cost reduction argument is compelling from a couple of perspectives.
The argument is never more persuasive, however, than it is for companies
that have a substantial volume of toll calls charged by the minute. VoIP can
reduce local charges; that’s a good thing. But VoIP also reduces or eliminates
most other classes of toll charges and greatly reduces your regulatory fees.
That is a great thing.
Depending on the number of locations your company has and how many toll
boundaries your current calling plan covers, you can save big bucks. This
savings is derived primarily from putting all your locations on VoIP and
bypassing most if not all of your toll charges. If your organization has significant
international calling, the same benefit accrues, except that your company
can save even more on toll and regulatory costs.
