To set up a modern business phone system, the VoIP solution is essential today. The 3CX solution I offer my clients is highly adaptable, allowing this SME to migrate quickly with skills transfer, making them autonomous in managing their SIP trunk and phones. The 3CX solution also supports iPhone and Android clients, as well as desk phones, and can be hosted anywhere (public cloud, private, VM, mini-server, even Raspberry Pi for very small setups!).
