"...Most important are: - inter-operation with a variety of top brand hardware: snom, Yealink, Fanvil, Htek (fully supported - plug and play provisioning); Aastra, Cisco, Gigaset, Panasonic, and Polycom are supported with more limited feature sets; door phones, PA gateway, Polycom and snom conference phones; several different brands of analog-to-IP and T1/E1-to-IP gateways are also supported, with easy-to-use wizard configuration tools - inter-operation with a long list of SIP trunk providers, with provisioning templates that are guaranteed to work with these providers' systems out of the box - administration Dashboard (web-based) is comprehensive, easy to use, and provides a number of very helpful status graphics; phones can be re-provisioned, rebooted, and firmware upgraded from the Dashboard - the free 3CXPhone soft phone for Windows, OS X, Android, iOS is packed with features like BLF soft keys which show status of other extensions on the system, access to end-user customizable call routing options, conference call scheduling, call recording option, call records, company and private directory, visual voicemail, and private Chat...."

"...WebRTC-based WebMeeting allow participants to join a web meeting with or without video, without having to download special software (Chrome and Mozilla currently supported); also includes document sharing, screen sharing, Chat, etc - the required Windows platform can be as small as an inexpensive hardware appliance running Windows 7/8/10 Pro (newest Atom or i3 CPU permits up to 16 simultaneous calls), or almost any flavor of Windows Server running on appropriate hardware, or installed as a virtual machine (both Hyper-V and VMware are supported); multi-tenant version is available for hosting providers - although a very small office would do very well with the Free version, 3CX is scalable to multiple sites and thousands of users, easily partitioned by departments/groups with fine-grained security restrictions to provide access only to desired users and features - pricing is based on number of simultaneous calls, not extensions (i.e. unlimited users with no additional licensing)...."
