| Area | 3CX | Zoom Phone | Australian buyer note |
|---|---|---|---|
| Core model | PBX-style business phone system with hosted, self-hosted, and on-premise paths. | Cloud phone service within Zoom Workplace, with domestic calling plans, SMS/MMS where available, fax, recordings, integrations, and app-based calling. | Compare phone-system control against Zoom ecosystem consolidation. |
| Pricing model | Commercial editions priced by simultaneous calls. | Zoom Phone pricing varies by plan and region, with metered/unlimited domestic options and international rates. | Check Australian plan availability, numbers, calling rates, SMS, support, and add-ons before buying. |
| Teams integration | 3CX integrates with Teams in specific editions/system sizes. | Zoom documents Zoom Phone for Microsoft Teams via app integration and Direct Routing-based approaches. | Useful if users want Teams interface plus Zoom Phone service, but setup and support need careful design. |
| Global coverage | Depends on hosting, trunks, and provider model. | Zoom says Phone provides local telephony service across 49 countries, with additional coverage through Provider Exchange partners. | Zoom can suit global Zoom-standardised businesses, subject to local compliance and availability. |

The real difference
3CX is PBX-first. Zoom Phone is Zoom Workplace-first.
3CX is a better fit when the project is centred on phones, call routing, SIP trunks, handsets, queues, and provider-managed PBX design. Zoom Phone is a better fit when business communications are already standardising around Zoom meetings, Zoom apps, AI, contact centre direction, and global admin.
The practical decision is less about whether each can make calls and more about where users should work all day: a dedicated phone system or the Zoom communications workspace.
A practical review should map
- Zoom adoption, Microsoft Teams usage, and app preference.
- Numbers, porting, emergency calling, SMS, fax, and call recording.
- Queues, auto receptionists, shared numbers, and reception workflows.
- Global users, local support, carrier path, and business continuity.
Where each option usually fits
3CX: phone-system design
Choose 3CX for PBX control, SIP trunks, local provider design, custom routing, and simultaneous-call economics.
Zoom Phone: Zoom consolidation
Choose Zoom Phone when users already trust Zoom and the business wants phone, meetings, messaging, and AI under one communications stack.
Hybrid path
Some businesses keep Zoom for meetings and choose a separate PBX platform for phones. That can be the right answer when voice workflows are more complex.
