Flexible in all directions? Thanks FreePBX

FreePBX is currently the most versatile open source IP PBX on the market

Over 2 million global community users use the all-in-one solution with easy-to-use web GUI and feature-rich web administration tools.

Not only the traditionally expected PBX features but many additional ingenious  features make FreePBX one of the most popular IP telephony systems. Free to download and install on your own hardware, there are hardly any other competitive systems in the worldwide ranking. The licensing is modular - depending on the needs of the company.

Basis for Unified Communication

If you want to promote your company with Unified Communication, you need a stable basis for communication over the Internet. And because today's stable does not mean stable tomorrow, it requires an active advancement, which Sangoma® Technologies (the company behind FreePBX) offers.

Not contact-shy

Technical compatibility with legacy or third-party systems is no problem for FreePBX. Whether it's a connection to analog phones or fax machines, to analog or digital PSTN networks or to SIP trunks for All-IP - you decide what you want to connect to - FreePBX offers the flexibility to do so.

Customized maintenance

Security, service and access to the latest versions - maintenance packages of different levels (Bronze, Gold, Platinum) are at your disposal.
