Benefits of Voice Over IP PBX systems

Why use a VOIP system?

Easier to manage because of web based configuration interface:

A VOIP phone system has a web based configuration interface, allowing you to easily
maintain and fine tune your phone system. Proprietary phone systems often have difficult to use interfaces which are designed so that only the phone system installers can use it effectively.

Call cost reduction:

You can save substantially by using a VOIP service provider for long distance or
international calls. Easily connect phone systems between offices/branches via the
Internet or WAN and make free phone calls.

No need for separate phone wiring – use computer network:

A VOIP phone system allows you to connect hardware phones directly to a standard
computer network port (which it can share with the adjacent computer). Software phones can be installed directly onto the PC. This means that you do not need to install & maintain a separate wiring network for the phone system, giving you much greater
flexibility to add users/extensions. If you are moving into an office and have not yet
installed phone wiring, you can save significantly by just installing a computer network.

No vendor lock-in:

VOIP phone systems are open standard – all modern IP PBX systems use SIP as a
protocol. This means that you can use almost any SIP VOIP phone or VOIP gateway
hardware. In contrast, a proprietary phone system often requires proprietary phones,
designed specifically for that phone system and proprietary expansion modules to add
features and lines.


Proprietary systems are easy to outgrow: Adding more phone lines or extensions often
requires expensive hardware upgrades. In some cases you need an entirely new phone
system. Not so with a VOIP phone system: a standard computer can easily handle a
large number of phone lines and extensions – just add more phones to your network to

Better customer service & productivity:

Because calls are computer based, it i s much easier for developers to integrate with
business applications. For example: an incoming call can automatically bring up the
customer record of the caller, dramatically improving customer service and cutting cost.
Outbound calls can be placed directly from Outlook, removing the need for the user to
type in the phone number.

Software based Phones are easier to use:

It i s often difficult to use advanced phone system features such as conferencing on
proprietary phones. Not so with software based SIP phones – all features are easily
performed from a user friendly windows GUI.

More features included as standard:

Because a VOIP phone system is software based, it is easier for developers to improve
feature sets and performance. Therefore most VOIP phone systems come with a rich
feature set, including auto attendant, voice mail, call queuing and more. These options
are often very expensive in proprietary systems.

Better control via better reporting:

VOIP settings store inbound and outbound call information in a database on your server,
allowing for much more powerful reporting of call costs and call traffic.

Better overview of current system status and calls:

Proprietary systems often require expensive ‘system’ phones to get an idea what is going
on in your phone system. Even then, status information is cryptic at best. With VOIP
systems you can define which users can see phone system status graphically via a web

Allow users to hot plug their phone anywhere in the office:

Users simply take their phone, plug it into the nearest Ethernet port and they keep their
existing number!

Allows easy roaming of users:

Calls can be diverted anywhere in the world because of the SIP protocol characteristics
