3CX
Why consider 3CX
The licence counts simultaneous calls, so the price tracks call volume instead of headcount
Self-host on your own AWS, Azure, Google Cloud or on-premises infrastructure, or take hosting from 3CX
Keep your own SIP trunks and buy carriage from whoever you like
Contact centre features (queues, skills-based routing, wallboards, call recording) come with the PRO edition of the phone system
Live chat, WhatsApp, Facebook and SMS reach agents in the same client as voice
CRM screen-pop for Salesforce, HubSpot, Zoho, Freshdesk and Zendesk, with a template API for anything else
Microsoft 365 and Google Workspace sync users, contacts and calendars
Windows or Linux server, with iOS, Android and browser clients included
AI Agent Capability
Call transcription, summaries and sentiment analysis in the ENT/AI edition. There is no native AI voice agent that can hold a call end to end. That job needs a separate platform connected over SIP.

Who is 3CX best suited for?
Australian organisations of roughly 10 to 200 users that want contact centre features at phone system prices, and are willing to own the infrastructure and SIP trunks, or have a partner own them.
Questions to Ask 3CX
- 01
Which region an Australian instance actually lands in, and on whose cloud. 3CX hosts AU and NZ instances on Google Cloud, at a lower stated uptime than the Vultr and DigitalOcean regions it uses elsewhere. Self-hosting in an Australian data centre is the alternative.
- 02
Evidence for the certifications resellers claim (ISO 27001, SOC 2, PCI DSS, HIPAA). Ask for the certificate and its scope. Also ask what changed in the build pipeline after the 2023 compromise of the 3CX desktop client.
- 03
What the licence costs now and what it covers. The 30 January 2026 change removed the free tier, ended perpetual licensing for mid-market, and applied a Fair Use Policy.
