Your IP PBX, Your Way: On-premises or in the Cloud
3CX is a software-based, open standards IP PBX that provides a complete Unified Communications solution that can be used immediately after installation.
3CX makes installing, managing and maintaining an IP PBX so easy that you can manage it yourself with little effort, whether on the device or on the server, on-premises or in your cloud account.
Along with significant cost savings, your business also gains numerous additional benefits, including:
Reduce travel and phone costs thanks to IP phones
The 3CX Unified Communications system not only offers numerous new features to enhance customer service, productivity, and efficiency, but it also slashes your phone expenses by half with its IP phone system and SIP trunk.
By implementing an IP phone system, you’ll see reductions in your phone bills as well as in the expenses associated with purchasing, expanding, and maintaining your switchboard. Opting for cloud hosting further decreases costs, as you can self-host and pay a nominal monthly fee per IP PBX instead of costly rates for extensions each month.
80% reduction in phone bills
Remote workers or those working outside the office can make free calls with 3CX’s calling software and mobile apps. Easily connect the phone systems of remote offices, improve communications and make all inter-office calls free. International DIDs and IP phone systems allow customers to make calls to you cheaply and increase customer satisfaction.

- Remote workers or sales staff call the office for free
- Save monthly call costs by using SIP trunk
- Take advantage of WebRTC & reduce your 800 phone number bills

An IP switchboard does not cost too much
Traditional phone systems or black box devices are really difficult to scale. To add more extensions, you will encounter problems such as licensing costs, underpowered hardware, or running out of ports. Cloud call centers are popular, but they can cost you expensive fees per extension and per minute…This is not the case with 3CX! Self-host through your own cloud provider or virtualize directly on your own hardware.
- No extension licensing required, just one low price for the entire switchboard
