On-premise doesn’t always mean hours of management and difficulty of use, at least not with 3CX’s on-premise PBX. 3CX’s on-premise PBX was designed with the admin in mind, ensuring that setup, management, and everyday use are effortless. You can even choose the operating system on which to run 3CX, either Linux or Windows. With an intuitive management console, plug and play IP Phones, SIP Trunks, and native CRM integrations, this on-premise PBX really is a walk in the park.
Setup and configuration of 3CX’s on-premise PBX are super easy and can be done with the minimum amount of downtime. 3CX has also made it easy to migrate from certain other PBXs with their migration tools.
On-premise should not be associated with being rigid and unscalable. Your on-premise PBX needs to offer you the flexibility and scalability your business needs as it grows. 3CX offers all this, both in its Cloud PBX and on-premise.



When it comes to VoIP security, 3CX sets the standard. 3CX did not hold back on any security features to ensure your data and information are safe and protected from hackers. With call encryption via the 3CX Tunnel and HTTPS for browsers as well as SRTP and SSL certs 3CX ensures your PBX is secure.
