In telephone systems,
a PBX (private branch exchange) is the switching device that
manages calls between internal or local users. It shares a
number of lines that connect to the external, public phone
system and parcels them out to the local users. Enterprise PBX
systems have features that allow them to take incoming calls,
send them to specific extensions, connect calls to answering
services, etc. |
|
|
|
 |
 |
| A PBX includes external phone
lines, a computer server to manages call switching, internal
phone lines and a console for manual control. |
|
|
 |
 |
| The VoIP PBX does all this and more. It switches and
connects VoIP calls. In dual technology systems, it
performs the same for regular telephone calls. |
|
|
 |
 |
| The VoIP PBX is programmable for advanced functions like
voice menu systems, automatic conferencing, click-to-call,
call logging and tracking and much more. |
|
|
|
|
|
|
| Using an VoIP PBX system and VoIP
telephone service allows an organization to combine (or
converge) voice and data networks into a single system for
cost-savings, simpler management and greater functionality. |
| VoIP PBX systems can come as software
for you to install on an existing server, or as pre-configured
software on a server, or even as a turnkey box that is
completely set up in advance to just connect to your existing
network. There are two main types
of VoIP options to choose from, a hosted VoIP service or
purchasing VoIP equipment. Hosted VoIP service (also referred
to as a virtual PBX) is the most common solution for small and
medium businesses. With hosted service, the hosted service
provider supplies the VoIP system managed and hosted externally
to your company. The only equipment you will need to purchase
will be the IP telephones and many times these can be leased as
well.
Alternatively, you may opt to purchase
your own VoIP phone system. In this case, the business buys the
phone system from a systems integrator, often the same provider
that services or maintains your current LAN network, and the
systems integrator installs the equipment on your premises. Your
business or a contractor you hire is responsible for the
maintenance and operation of the system, ie hardware, software,
firmware etc.
If you purchase the system, keep in
mind that there may be additional network equipment needed as
well as dedicated servers and reliable battery backup systems.
Network integrity testing should also be done before
implementing a customer owned solution.
There are cost savings to consider when
implementing VoIP for your business. A study done by Nemertes
Research, called “Convergence: Reality at Last”, found that the
typical implementation cost per CPE (customer premises
equipment) VoIP user ranged from $525 for deployments of over
1,000 users to $763 for deployments of 100 or less. As users
increase, though, so do the savings per user. Price ranges for
hosted VoIP services average between $2,000 to $3700 per month
based on 20 phones with a T-1. Hosted services require
one-time set-up and activation fees that typically range between
$500 and $1,000.
Server Colocation Hosted VoIP phone service affords the small
business the ability to get high-end services at a fraction of
the initial CPE outlay costs.
VoIP, while once considered unstable,
has now become a reliable communication solution.
Distributing call processing functions across the network
eliminates any single point of failure. Choppy calls, once the
number one complaint among users, have now stabilized thanks to
newer technology and better networks. Providers are moving
towards a new standard for the VoIP network, H.323. Power
backup systems are normally utilized to keep the network up in
the case of a power outage.
Both hosted VoIP phone services, i.e.
server colocation
Hosted PBXs and customer owned VoIP systems (premise based IP
PBXs) offer a great deal more adaptability than traditional PBX
systems. Features can be added to telephone sets easily.
Changes can be made quickly. MAC (moves, adds and changes)
activity is easily completed without the need for a technician
to come to site, saving about $100 per visit. VoIP allows you
to move your own telephone sets while keeping the telephone
number and features intact. You simply unplug your phone and
plug it into another jack location that is connected to the
network. As new features and applications are designed they can
be added to your network. |

A VoIP PBX system is a piece of software running on a
server . That server can also perform other tasks, but
is usually dedicated and also acts as the VoIP system's
connection to the internet. |

Why do you need
a VoIP PBX? |
 |
What you need in
an VoIP PBX |
 |
 |
| Any IP telephony setup that is for more than two or
three lines needs a switching system to make it efficient,
allow internal calling and switching between users and for
advanced features like voicemail, call forwarding, call
hold, conferencing and more. Typically VoIP PBX systems
become economically sensible with as few as 5 users and a
good rule of thumb is that if you want an IP telephony
system with extensions for your users than you may want an
VoIP PBX. Market analyst estimates show that there is
rapid migration to IP telephony because of cost, efficiency
and performance advantages. All organizations, even a small
ones that migrate to VoIP or IP telephony will need an VoIP
PBX system. In the past PBX systems for organizations and
enterprises were cost prohibitive so that only large
enterprises could afford to make use of them, but recent
technological advances and pressure from open source
solutions has brought the cost of VoIP PBX systems down to
as low as well under $1000. |
|
| There are many of VoIP PBX systems
and most of them can do an adequate job. Regardless of the
size of your organization, any VoIP PBX should be able to do
the following: Automated attendant-an auto system to
answer phones with the ability to build phone menu systems,
add call menus, transfer to voicemail and create flexible
and programmable rules to handle all of these features.
-Call menus-flexible call management menus with user
selectable options – an advanced version of the traditional
phone tree/menu systems. A quality system will allow you to
have multiple menus and even change them based on time or on
information gleaned from caller ID.
-Managing extensions-features to help
the phone system administrator by allowing the addition of
new extensions, removal of unneeded extensions,
changing of extension locations and
much more from a web-based control panel |
|
|
 |
|
Standard Features:
|
 |
 |
 |
 |
-Voicemail and voice mailboxes: Any IP-PBX should allow an
almost infinite number with far more flexibility than
regular phone systems -- advanced features would include the
ability to record ALL incoming and outgoing conversations
automatically. -
Call forwarding:
automatic, programmed or manual call forwarding to any
number -Call hold-placing callers properly on hold with no
drop off in queues with user selectable hold music and
programmable options about handling hold time length.
Conference calling:
handling multi-party conference calls – both internally
and externally -Branch office support-the ability to manage
and remotely administer extensions at other offices just as
if they were local
Web-based management and administration:
Make it quick and easy to manage your phone system
directly from a web browser -- this includes the ability to
add end-user configuration and management functions as well
-Some form of integration into your basic data network so
that 'click-to-call' functionality can be added or even full
blown CRM systems. |

VoIP service & systems are feature rich. They provide all
the traditional features you expect such as three-way
calling, voicemail, speed dialing and caller ID. In
addition, VoIP phone systems provide other more advanced
features. These are just some of the many available
features. Call Queing - allows calls to be put into queues
to be answered in turn by a designated group of extensions.
Call Center - enables you to set up calling and answering
groups for specific tasks such as marketing, sales and
service.
Remote Office Features – provides features that integrate
off-site locations such as satellite offices, allowing them
to function as part of the main office.
Attendant Console – an integrated control system that
manages calls and functions from a single interface.
Find / Follow Features – features that automatically
route calls to employees regardless of their location. Calls
can be presented to multiple locations simultaneously.
Fax – VoIP supports faxing. Fax can be added to each
individual’s inbox.
PC Calling – also called click to call, calls can be
placed and received via the PC. This may take the place of
some cell phone usage, such as making a call from a laptop
over a high speed Internet connection in a motel instead of
using a cell phone.
Enhanced 911 – When dialing 911 it automatically sends
the address of your location to the emergency personnel. |

Additional Considerations::
|
 |
 |
 |
 |
Maintenance - Hosted PBX VoIP providers offer time and cost
savings by providing ongoing maintenance at their
off-premise location. Customer owned VoIP solutions afford
the ability to reduce administrative costs by incorporating
all voice and data solutions into a single management
interface. This interface can often include gateways,
controllers, telephones and applications.
Infrastructure –
Traditional PBX telephone systems required at least one pair
of wires to the desktop. With VoIP, only one cable (a data
connection) is needed to the desktop, which will accommodate
both voice and data. The cost savings realized by running
less cable in a new office scenario could average $70 to
$100 per station.
Customer Service -
An important consideration is the service level
your provider offers. Hosted VoIP service providers
typically offer an excellent range
of options for service and maintenance. Look for
service that includes 7 x 24 x 365 coverage. Many options
also include a number of support hours that enable you to
utilize provider network support. MAC (moves, adds and
changes) pricing is separate and providers usually offer a
24-hour turn-around time. Upgrades may be included in your
package. The cost of your service plan will be based on the
number of elements that are host controlled. Ala Carte
support items are also available. Business VoIP providers
offer competitive services that may be able to custom-tailor
a plan for you, so ask your representative.
Productivity -
Converged applications such as unified messaging enable
users to spend less time working between different systems
to retrieve messages. With a VoIP phone service or system,
your voice messages, e-mails and faxes can all be delivered
to one desktop account. Other capabilities such as click
to call and Microsoft Outlook integration save time.
Efficiency also increases, as staff members are able to
answer their calls no matter where they are with “find me –
follow me” capabilities. Phone tag is reduced. A survey
conducted by Sage Research showed an increase in
productivity of up to 3 hours per week.
Cutting Edge
–With its converged services and adaptability, VoIP phones
are here to stay. VoIP is easily updated to latest versions
of software, giving you access to the newest technology
available. This keeps you a step ahead of your competition,
poised to allow even more enhancements. The future
offerings are limitless, with likely further integration to
include CRM and other customized business process tools. |
