3CX is free for up to 8 sim calls and for larger installs it’s available at one low yearly price. You have complete freedom on where to install it, which SIP trunks or IP phones to use – saving thousands per year. Setup 3CX in minutes – in the cloud using our PBX Express tool or using the wizard for on-premise installs.
You decide where to run 3CX – run it on an existing server using VMware or Hyper V. Smaller installations can run on a low cost PBX appliance from Intel NUC, Shuttle, Zotac, Zbox & Gigabyte. Easily move your PBX to another server or into the cloud, using built-in backup and restore.
Whether in the cloud or on premise – You are in control. Self host on popular cloud providers offering standard Linux VPS. Pay a low monthly fee per PBX rather than an inflated price per extension and long term contracts. There is also the option to outsource to a managed 3CX hosting partner.
