Office Telephones

Much easier to install & configure than a proprietary phone system:
An IP PBX runs as software on a computer and can leverage the advanced processing power of the computer and user interface as well as features. Anyone proficient in networking and computers can install and maintain an IP PBX. By contrast a proprietary phone system often requires an installer trained on that particular system!

Easier to manage because of web/GUI based configuration interface:
An IP PBX can be managed via a web-based configuration interface or a GUI, allowing you to easily maintain and fine tune your phone system. Proprietary phone systems have difficult-to-use interfaces which are often designed to be used only by phone technicians.

Significant cost savings using VoIP providers:
With an IP PBX you can easily use a VOIP Provider for long distance and international calls. The monthly savings are significant. If you have branch offices, you can easily connect phone systems between branches and make free phone calls.

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

Twice the phone system features for half the price!
Since an IP PBX is software-based, it is easier for developers to add and improve feature sets. Most VoIP phone systems come with a rich feature set, including auto attendant, voice mail, ring groups, and advanced reporting. Unified Communications features are included, to support presence, video and audio conferences and free calls via the data network. These options are often very expensive in proprietary systems.
