3CX Phone System

3CX Phone System is a specialist, Debian-based Linux distribution designed to run a complete unified communications platform. The 3CX client, included in the distribution, is a secure, scalable business phone system and contact center solution designed for companies with 25+ users; it can be hosted on-premise, in a private cloud or through a managed service – all for a single annual rate, with no per-user charges and no third-party data sharing. The ISO image includes a free license for the 3CX PBX edition. The ISO image contains the standard Debian installer which installs a minimal system with the nginx web server, PostgreSQL database, iptables firewall and Secure Shell. Options not relevant to 3CX have been removed from the distribution.
