3CX vs RingCentral at a glance
This comparison is not a simple feature checklist. 3CX and RingCentral differ most in deployment model, pricing assumptions, operational control, Teams approach, and how much of the communications stack you want under one vendor.
| Area | 3CX | RingCentral | Australian buyer note |
|---|---|---|---|
| Core model | PBX-style business phone system with hosted, self-hosted, and on-premise paths. | Cloud communications platform centred on RingEX for AI-powered calls, messages, and meetings, with adjacent contact centre, events, and AI products. | Start by deciding whether this is a phone-system replacement or a broader communications standardisation project. |
| Pricing model | 3CX PRO and Enterprise/AI are priced by simultaneous calls. 3CX pricing emphasises a flat annual system cost rather than per-user monthly pricing. | RingCentral’s AU pricing page positions RingEX around users and plan selection, with annual-payment savings promoted. Final cost depends on plan, users, calling, contact centre, AI, Teams, devices, and services. | Model the whole contract, not just the headline licence. Include local numbers, calling, implementation, support, recordings, analytics, AI, and contract terms. |
| Deployment | Hosted by 3CX, self-hosted, Windows/Linux, and on-premise options. | Cloud-first SaaS service delivered through RingCentral apps, admin tools, and global infrastructure. | 3CX gives more infrastructure and carrier control. RingCentral reduces PBX ownership but increases reliance on the vendor platform. |
| Calling and PBX features | Strong PBX features, SIP trunks, ring groups, queues, apps, web client, live chat, WhatsApp, SMS, CRM, Teams, and AI options by edition. | RingCentral promotes cloud phone features across calls, texts, fax, call routing, caller ID, automated replies, business hours, recordings, analytics, and integrations. | Both cover mainstream business calling. The difference is whether you want PBX-style configurability or a packaged cloud communications suite. |
| Microsoft Teams | 3CX Enterprise/AI Edition for 16 simultaneous calls and above supports Teams Direct Routing integration. | RingCentral offers a Microsoft Teams integration and RingCentral Cloud PBX for Teams, including Teams calling experiences, PBX features, fax, and Direct Routing options. | If Teams is central, compare the user experience, licensing, admin model, compliance, and support ownership carefully. |
| Contact centre | Integrated contact-centre features depending on edition, including queues, wallboard, callback, reports, and related tools. | RingCentral offers RingCX and contact centre solutions with AI-first positioning, omnichannel engagement, agent workspace, virtual agents, workforce engagement options, and UC integration. | RingCentral is usually stronger for formal cloud contact centre projects. 3CX may suit phone-queue-heavy environments. |
| AI | 3CX includes AI features such as transcription and AI agents depending on edition and configuration. | RingCentral heavily positions AI across RingEX, AI Assistant, AI Receptionist, RingCX, conversation intelligence, and workflow automation. | AI capabilities are changing quickly. Confirm availability, licensing, data handling, retention, and Australian compliance needs before buying. |
| Global reach | 3CX can be deployed globally, but carrier service, support, hosting, and regulatory handling depend on your provider model. | RingCentral promotes enterprise reliability, global availability, 45+ countries with Global RingEX product availability, 100+ countries for virtual phone numbers, and 30+ private data centres in its press kit. | RingCentral can be attractive for Australian firms with overseas offices, international hiring, or multi-country customer service. |
| Best fit | Businesses wanting PBX control, SIP trunk flexibility, self-hosting or on-premise options, and provider-led management. | Businesses wanting cloud UCaaS, Teams options, AI, contact centre pathways, global scale, and vendor-managed communications. | The right choice depends on control versus consolidation. |
The real difference
3CX is a phone-system architecture decision. RingCentral is a cloud-platform decision.
3CX appeals when the phone system itself is the centre of the project. You can choose hosting models, SIP trunks, phone provisioning methods, routing design, and who manages the platform. That can be efficient and flexible, especially for businesses that already have a trusted Australian voice provider.
RingCentral appeals when the business wants to reduce infrastructure ownership and standardise communications as a SaaS platform. Its Australian pages position RingCentral around AI-powered phone, messaging, video, contact centre, Microsoft Teams, events, and a larger app and integration ecosystem.
A practical review should map
- Users, call volume, simultaneous calls, and licence economics.
- Existing SIP trunks, numbers, handset models, and porting constraints.
- Microsoft Teams, Microsoft 365, CRM, helpdesk, and analytics requirements.
- Contact centre, call recording, AI, data retention, privacy, and support ownership.
Where 3CX usually makes more sense
You want call-flow and trunk control
3CX is a better fit when your provider or IT team wants direct control over call routing, SIP trunks, extensions, phone provisioning, hosting, and emergency-calling setup.
Concurrent-call pricing suits you
If you have many users but modest simultaneous call volume, 3CX’s simultaneous-call pricing can be commercially attractive compared with per-user cloud bundles.
You need deployment choice
3CX supports hosted, self-hosted, Windows/Linux, and on-premise paths. That matters when infrastructure control, local survivability, or provider-managed architecture is part of the requirement.
Where RingCentral usually makes more sense
You want one cloud communications platform
RingCentral is stronger when the goal is to consolidate phone, messages, meetings, fax, analytics, integrations, and AI features into a vendor-managed cloud service.
Your Teams experience matters
RingCentral has a dedicated Microsoft Teams story, including an embedded app and Cloud PBX for Teams options. That can matter when staff already live in Teams but need richer calling, fax, SMS, or PBX features.
You are moving toward AI and contact centre
RingCentral’s current positioning is heavily AI-led, with RingEX AI Assistant, AI Receptionist, RingCX, omnichannel contact centre, virtual agents, and conversation intelligence options.
Australian considerations before switching
Emergency calling and location
Triple Zero (000) is Australia’s main emergency number and can be dialled from fixed and mobile phones and certain VoIP services. Confirm emergency routing, caller ID, service addresses, remote-user handling, and support escalation before migrating.
Power and NBN resilience
ACMA notes that most services connected to the NBN will not work during a power outage, which can also affect 000 calling. Plan mobile fallback, secondary internet, UPS power, and call-forwarding continuity.
Data, recordings, and compliance
Before changing systems, document where call recordings, transcripts, analytics, contact centre data, SMS, voicemails, and user records will live, who can access them, and how retention is managed.

Frequently asked questions
Is RingCentral a good 3CX alternative?
Yes, if you want a cloud communications platform rather than a PBX-style replacement. RingCentral is especially relevant when Teams, AI, contact centre, global users, analytics, and app integrations are part of the project.
Is 3CX cheaper than RingCentral?
It depends. 3CX prices commercial systems by simultaneous calls, while RingCentral is sold as a cloud platform with user, plan, service, and add-on variables. Compare total cost across licences, calling, hosting, support, contact centre, AI, devices, and migration.
Which is better for Microsoft Teams?
Both can be relevant. 3CX offers Teams Direct Routing integration in specific editions and system sizes. RingCentral has a dedicated Teams integration and Cloud PBX for Teams offering. The better choice depends on whether you want Teams as the front-end, RingCentral as the phone layer, or a separate PBX model.
Which is better for contact centres?
RingCentral is usually the stronger starting point for formal omnichannel contact centre projects. 3CX can still suit businesses that mainly need PBX queues, reporting, callback, wallboards, and phone-centred call handling.
What should Australian businesses check before changing phone systems?
Check emergency calling, service addresses, number porting, SIP trunks, 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.
