Phone system as software on server or cloud, smartphone app, web meeting included.

Classic phone systems with ISDN cards and proprietary hardware are not up-to-date in 2026 — and expensive. 3CX replaces this with a software PBX that runs on a normal server or in the cloud. Smartphone app for every employee, browser telephony, video conferencing and live chat — all included. Licence costs are paid per installation, not per extension.

What makes 3CX special

Three points: software instead of hardware (runs on Linux or Windows server, no separate phone device), app-first (smartphone app is a full extension, every employee is reachable everywhere), licence model per installation (not per extension — you can connect any number of employees without licence costs scaling linearly).

What 3CX can do

Classic telephony functions are standard: queues, IVR, call recording, voicemail, faxes as email. Plus modern: WebMeeting (video conferencing in browser without software installation), live chat widget for your website (chat goes to reception phone), WhatsApp integration, CRM integration with common systems.

3CX in practice

In medical practices 3CX is particularly popular for: caller identification via CRM connection (patient data pops up on call), call pre-recording (patient says name and concern, reception sees it beforehand), app on every practitioner phone (practitioner can forward call from treatment room or answer themselves).
