3CX Phone System for Windows is a software-based VoIP PBX that replaces a proprietary hardware PBX. 3CX has been developed specifically for Microsoft Windows and is based on the SIP standard, making it easier to manage and allowing you to use any SIP phone (software or hardware). 3CX offers many benefits:

  • Easier to install & manage via web-based configuration interface
  • Far less expensive to purchase and expand than a hardware-based PBX/PABX
  • Improve productivity with presence, desktop based call control and extension management
  • No need for separate phone wiring – phones use computer network, easy hot desking!
  • Deliver mobility by allowing employees to work from home using a remote extension
  • Choose between popular IP hardware phones or softphones - no vendor lock-in
  • Receive & make calls via the standard PSTN using VoIP Gateways or cards
  • Save on monthly call costs using SIP trunks, VoIP providers or the Skype gateway!


3CX includes VoIP clients for Android and iOS which allow you to take your office extension with you anywhere. Answer calls via the office phone extension and transfer to colleagues without asking customers to call another number.

3CX integrates powerful clients for Mac and Windows, allowing you to easily manage your phone calls, whether in the office using your deskphone, or on the road using the inbuilt softphone.

Presence, fax & voice mail to email, web conferencing, and instant messaging are child’s play for 3CX Phone System. With the integrated 3CX clients, users automatically get access to advanced unified communications features.

3CX also has an easy-to-use web conferencing solution that enables businesses to save time and money by hosting virtual meetings, whilst enjoying the benefits of face-to-face communication.
