#1 Enterprise phone system hosted or self hosted
3CX is an enterprise phone system hosted in the cloud or self-managed that lets you keep control of your own trunks and numbers too. It's a complete communications platform - eliminating the cost and management headaches of running multiple systems.
Unlike most other enterprise phone systems 3CX doesn’t charge on a monthly user basis. Instead, you pay once a year - at a very low cost - based upon concurrent calls.
An easy to manage and deploy enterprise phone system - combined with no multi-year contract lock-in's - it's the PBX of choice for 350,000 installs and counting.
Open-standard advantage
3CX leverages SIP - an open-standard protocol - and WebRTC technology ensuring compatibility with a wide range of VoIP hardware and services.
Want to self manage and self host?
3CX is easy to manage - your IT can do it. Host 3CX direct via marketplaces on Amazon Azure, Google or Digital Ocean. Or take advantage of 3CX Hosting.
Coming from Avaya or Mitel?
First of all, 3CX is much easier to manage. Secondly - and most important of all - 3CX is a fraction of the price of legacy systems because it's not proprietary to 3CX.
