Where to get 3CX as a Hosted PBX
In addition to being an on-premise phone system, 3CX’s VoIP solution is also designed to run in the cloud as a hosted PBX with a whole suite of Unified Communications features included. You can choose to self-host your business phone system via one of many providers that offer a Linux VPS or you can get 3CX from a managed hosted PBX provider. In both cases, you get a fully virtualized, dedicated instance of 3CX.
These hosted PBX providers offer you with a managed hosted instance meaning they will install, manage and support the hosted PBX for you.
