FreePBX is an all-in-one IP PBX that is completely Free to download and install onto your own hardware and includes all the basic elements you need to build a phone system. It is supported by Sangoma developers and by a global community of enthusiasts which help make FreePBX the most popular open-sourced IP-PBX on the market to date. It is controlled by a fully-featured webGUI which makes it very easy to use and deploy.
The power and flexibility of FreePBX comes from the dozens of feature add-ons (which we call ‘commercial modules’) that allow you to add individual features to FreePBX, tailored to your business needs, as you scale. Add features such as Zulu Desktop and softphone integration, CRM integration, Call-Center features, High Availability and more! Since FreePBX is automatically connected to the FreePBX Store, all you need to do is login, select your add-on, pay upon check-out and your new feature is instantly connected to your IP PBX. Better yet, you can purchase commercial modules directly from the FreePBX WebGUI, so you have instant access to the features and tools you need, when you need them!
