3CX vs Aircall at a glance
Aircall is not a like-for-like PBX replacement in the same way Yeastar might be. It is better understood as a cloud calling and customer communications layer for teams that spend their day inside CRM, helpdesk, and customer workflows.
| Area | 3CX | Aircall | Australian buyer note |
|---|---|---|---|
| Core model | PBX-style business phone system with hosted, self-hosted, and on-premise paths. | AI-powered customer communications and cloud phone platform for sales, support, and customer-facing teams. | Decide whether you are replacing a phone system or improving team-based customer conversations. |
| Pricing model | 3CX PRO and Enterprise/AI are priced by simultaneous calls, not pure per-user SaaS seats. | Aircall pricing is licence-based, with Essentials, Professional, and Custom plan paths, annual billing options, add-ons, and minimum licence assumptions. | Compare total cost across licences, phone numbers, calling, AI, analytics, onboarding, support, and integrations. |
| Deployment | Hosted by 3CX, self-hosted, Windows/Linux, and on-premise options. | Cloud service used through web, desktop, and mobile apps, with numbers and workflows managed in Aircall. | 3CX gives more infrastructure control. Aircall reduces PBX ownership and is easier to roll out for distributed teams. |
| Calling features | Ring groups, queues, IVR, apps, web client, call recording, reporting, live chat, WhatsApp, SMS, CRM, Teams, and AI options by edition. | Aircall promotes IVR, call recording, click-to-dial, SMS/MMS availability, call routing, queues, ring groups, shared contacts, warm transfer, shared inbox, and call commenting. | Both cover business calling, but Aircall is designed around team workflows rather than PBX administration. |
| Call centre | Suitable for PBX-centred queues, wallboards, reporting, callback, and supervisor workflows depending on edition. | Aircall call-centre features include call routing, monitoring, business hours, after-call work, analytics, queues, callback, warm transfers, and live note taking/tagging. | Aircall is usually stronger for sales/support call teams that want speed and app integrations. 3CX may suit broader PBX replacement. |
| Integrations | CRM and Microsoft 365/Teams options depend on edition and configuration. | Aircall positions 250+ integrations and API access, with CRM, helpdesk, and productivity tools central to the product. | If HubSpot, Salesforce, Zendesk, Intercom, or similar systems drive your workflow, Aircall deserves a close look. |
| Microsoft Teams | 3CX supports Microsoft Teams Direct Routing integration in specific editions and system sizes. | Aircall offers a Microsoft Teams integration for launching customer calls, sharing contact details, and collaborating from Teams. | Teams-heavy businesses should compare user experience and administration, not just whether an integration exists. |
| International numbers | Global deployment depends on trunks, hosting, local providers, and support model. | Aircall says it can provide numbers in more than 100 countries, subject to local regulation and number portability limits. | Good for distributed customer-facing teams, but check Australian number support, porting, emergency calling, and call costs. |
| Best fit | Businesses wanting PBX control, SIP trunk choice, deployment flexibility, and provider-led management. | Sales, support, and customer service teams wanting cloud calling tightly connected to business apps. | The right choice depends on whether voice is infrastructure or a front-line workflow tool. |
The real difference
3CX is a PBX decision. Aircall is a customer-workflow decision.
3CX is the stronger fit when the phone system itself is the project: trunks, sites, extensions, desk phones, call routing, recording, queues, and hosting. That matters when a provider needs to design the system around existing Australian carrier and site requirements.
Aircall is the stronger fit when calling is one part of a front-line customer workflow. Its official positioning emphasises calls, SMS, messaging, shared workspaces, CRM/helpdesk connections, AI Voice Agent, AI Assist, analytics, and a platform sales and support teams can use quickly.
A practical review should map
- Users, phone numbers, call volume, and licence economics.
- CRM, helpdesk, sales, support, and reporting workflows.
- Queues, callbacks, call monitoring, call recording, AI summaries, and analytics needs.
- Australian numbers, porting, 000 routing, NBN resilience, and support ownership.
Where 3CX usually makes more sense
You need PBX architecture control
3CX is a better fit when sites, trunks, phones, call routing, recording, failover, and support model need to be designed as a managed phone system.
Concurrent-call pricing suits you
If you have many staff but relatively few simultaneous calls, 3CX’s simultaneous-call model can be more efficient than licence-per-user platforms.
Desk phones and carrier strategy matter
3CX is often a better starting point when you already have desk phones, SIP trunks, number ranges, branch sites, or carrier contracts that need careful migration planning.
Where Aircall usually makes more sense
Your team lives in CRM or helpdesk tools
Aircall is built around integrations. If customer records, tickets, deals, and call notes need to stay connected, Aircall may reduce manual work faster than a traditional PBX migration.
Sales and support need speed
Aircall’s cloud model, app-based experience, call routing, call tagging, shared inbox, click-to-dial, and analytics are useful when the goal is fast team adoption rather than deep PBX customisation.
AI and analytics are part of the brief
Aircall’s current pricing and product pages emphasise AI Voice Agent, AI Assist, call summaries, analytics, and conversation visibility. Confirm exact inclusion and add-on pricing before buying.
Australian considerations before switching
Emergency calling and location
Triple Zero (000) is Australia’s main emergency number and can be called from fixed and mobile phones and certain VoIP services. Confirm emergency routing, caller ID, service addresses, and remote-user assumptions before moving.
Power and NBN resilience
Most NBN-connected services will not work during a power outage. Whether you choose 3CX or Aircall, plan mobile fallback, secondary internet, UPS power, and call-forwarding continuity.
Numbers, recordings, and data
Before changing systems, confirm number portability, call recording retention, transcript storage, CRM sync behaviour, Australian privacy obligations, and who supports issues after go-live.

Frequently asked questions
Is Aircall a good 3CX alternative?
Yes, if the main requirement is cloud calling for sales, support, and customer-facing teams. Aircall is less of a PBX replacement and more of a customer communications workspace with integrations, analytics, and AI options.
Is 3CX cheaper than Aircall?
It depends. 3CX prices commercial systems by simultaneous calls, while Aircall is licence-based with plan tiers, add-ons, and minimum licence assumptions. Compare total cost across users, numbers, calling, AI, analytics, integrations, support, and migration.
Which is better for call centres?
Aircall is usually stronger for sales and support call teams that need CRM/helpdesk integration, call tagging, monitoring, analytics, callback, and app-based workflows. 3CX can still suit PBX-centred queues and broader business phone replacement.
Does Aircall work with Microsoft Teams?
Aircall offers a Microsoft Teams integration for customer calls, contact sharing, and collaboration. Teams-heavy businesses should compare how users will actually place calls, receive calls, see status, and access customer context.
What should Australian businesses check before changing phone systems?
Check emergency calling, number porting, call costs, NBN and power resilience, mobile fallback, call recording retention, privacy obligations, support ownership, and whether the new platform fits Microsoft 365, CRM, helpdesk, and reporting workflows.
