What is 3CX?

3CX is a business communications platform providing PBX calling, video conferencing, live chat, and SMS/WhatsApp messaging from one system. It can be self-hosted on-premises, deployed in a private cloud, or run as a 3CX-hosted instance, and it includes a call flow designer, call center features like queues and recording, and AI-based voicemail and call transcription on higher tiers.

Unlike most per-user cloud phone systems, 3CX is licensed annually per system based on simultaneous call capacity rather than per user, which can lower costs for organizations with many extensions but fewer concurrent calls. 3CX removed its free entry-level tier in early 2026, moving all customers to paid PRO or Enterprise licensing. It integrates with Microsoft 365, Google, and CRMs like Salesforce and HubSpot.

3CX lists 9 documented features, including PBX calling, video conferencing, and live chat in one platform, Call Flow Designer for custom call routing without coding and Call center features including queues, recording, and SLA reporting.
