What is RingCentral RingEX? UCaaS Guide for ANZ Businesses

Most businesses have built their communications setup the same way they've built everything else — one piece at a time, over years, adding tools as problems come up. The price to pay isn't the numerous licence fees, but it's the new starter still waiting on a desk phone setup after 5 days, and the manager who only finds out something went wrong when a complaint lands.

At Kaizn, we're independent. We work across multiple vendors and we recommend based on fit, not what's easiest for us to sell. This post covers RingCentral's RingEX — one of the UCaaS platforms we work with — because it comes up a lot when businesses ask us how to fix the communications gap that sits outside their contact centre.

What is UCaaS?

UCaaS stands for unified communications as a service. In plain terms, it replaces the collection of disconnected tools your business uses to communicate — desk phones, mobile plans, video conferencing apps, team chat — with one cloud-based platform your team accesses from any device, from anywhere.

The "as a service" part means:

• No hardware to buy or maintain
• No on-site servers or IT infrastructure
• Automatic updates and security patches managed by the vendor
• Pay per user, per month — scale up or down as the business changes

RingCentral's RingEX is one of the leading UCaaS platforms in the ANZ market. It's the platform we most commonly recommend to businesses looking to consolidate back office communications under Kaizn Essentials.

How UCaaS works

UCaaS platforms run on cloud infrastructure managed by the vendor. Your team accesses communications the same way they access any other cloud application — through a browser, a desktop app, or a mobile app.

Here's what that means in practice:

• Calls, messages and video sync in real time across every device your team uses
• A call that comes in on the desktop app rings the mobile app simultaneously
• Numbers and extensions follow people, not desks — a team member working from home has the same business identity as one sitting in the office
• New starters are provisioned through an admin portal in minutes, with no hardware required

The vendor handles maintenance, security patches, uptime, and infrastructure. Your IT team configures the platform through an admin console rather than managing physical equipment.

UCaaS vs CCaaS — what's the difference?

This is the question we get most often from contact centre leaders.

UCaaS is built for internal team communications and general business calling. Calling, video, messaging and SMS for every employee across the organisation. It's optimised for communication flexibility across the whole business.

CCaaS (contact centre as a service) handles high-volume, queue-managed customer service interactions. Inbound call queues, agent routing, workforce management, customer analytics. It's optimised for customer-facing volume at scale.

They solve different problems for different parts of the organisation. Most businesses running a contact centre need both — CCaaS for the contact centre floor, UCaaS for everyone else.

If you're running Zoom, MaxContact, Genesys, or any other CCaaS platform, that's your contact centre sorted. UCaaS is the conversation about what happens outside that floor.

UCaaS vs on-premise PBX

Many ANZ businesses are still running on-premise PBX systems — physical hardware installed on-site that routes calls through a fixed location.

The limitations are well understood but often accepted as normal:

• Location-bound — staff can only take calls where the hardware is installed
• Expensive to scale — adding capacity means buying more hardware
• No native AI — AI features require significant third-party add-ons
• IT-intensive — maintenance, upgrades and moves are all manual
• Not built for hybrid — distributed teams require significant workarounds

UCaaS removes all of those constraints. The phone system lives in the cloud, your team connects from anywhere, and the vendor absorbs the infrastructure burden.

5 core UCaaS components

A UCaaS platform consolidates core communication channels into one place. For RingCentral RingEX, those are:

‍1. Voice calling (VoIP) Cloud-based calls replace traditional phone lines. Call routing, auto attendant, call recording, voicemail-to-email. Your team makes and receives calls from any device using a business number — no desk phone required.

2. Video meetings Integrated video conferencing for internal and external calls. Screen sharing, recording, and AI-generated meeting summaries included.

3. Team messaging Persistent, channel-based messaging with file sharing and task tracking. Context stays with the conversation rather than scattered across email threads.

4. Business SMS Two-way SMS from a business number. Conversation history stays in the platform, visible to the team, tied to the right business line.

5. AI-powered features AI is now core to the platform, not an optional add-on. RingEX includes AI Receptionist, AI Conversation Expert (ACE), and a Personal AI Assistant — more on these below.

AI features in UCaaS: what to expect in 2026

This is where the market has moved most rapidly. The difference between UCaaS platforms right now often comes down to how their AI actually works.

‍Native AI vs third-party integrations

Native AI runs across every channel inside the same platform. When a call ends, a summary auto-generates. When a message comes in another language, translation happens in-thread. Routing logic draws on caller history.

Third-party AI integrations create data silos — transcription might work in meetings but not calls, summaries might appear in one channel but not another.

RingCentral's AI suite runs natively across RingEX. It includes:

• AI Receptionist (AIR) — answers inbound calls 24/7, handles FAQs, routes complex enquiries, books appointments
• AI Conversation Expert (ACE) — analyses every call for sentiment, recurring issues, coaching opportunities and compliance flags. Available as part of RingEX.
• Personal AI Assistant — automatic transcription, call summaries, action items and meeting recaps
• Smart routing — routes calls based on conversation context and caller history, not just button presses

What this looks like in practice: AusHealth, an Australian medical research charity running 100 agents across Adelaide, Brisbane and Melbourne, deployed ACE to automate compliance monitoring. The system flagged an agent doing urgent roadside post-incident testing who was talking at 250 to 260 words per minute — something no manual review had caught. That insight went straight into coaching. Their CEO described the visibility as something the business had never had before.

Benefits of UCaaS for ANZ businesses

Stop losing customers to a phone that didn't get answered

Five missed calls a day is 1,200 missed opportunities a year. They don't show up in a sales report or a churn metric — they disappear silently. AI Receptionist answers every inbound call automatically, 24/7, without adding headcount.

In practice: Integral Recruiting Services deployed AI Receptionist and cut their call volume needing a human by 90%, recovering 8 to 10 hours a month previously lost to spam calls and manual routing.

Connect multiple offices onto one platform

Symmetry Human Resources had six offices across Australia, each on a separate phone system. Transferring a call between cities was nearly impossible. After moving to RingEX, managers had complete national visibility, staff used their personal mobiles with a business identity, and new starters were onboarded the same day regardless of location.

Give management the visibility they've never had

Most managers don't know what's being said across their team's calls until something goes wrong. ACE analyses every call automatically — no manual listening required. Sentiment, coaching flags, compliance issues and recurring themes surfaced without any additional headcount.

Support hybrid and remote teams without the infrastructure headache

Desk phones tie people to locations. RingEX runs in the cloud — the same number and setup follow people wherever they're working. New users are provisioned in minutes. No hardware, no IT ticket, no waiting.

In practice: AusHealth's field teams now take calls on personal phones via the RingCentral app. Staff on 24/7 rosters respond to urgent calls wherever they are, without being tied to a desk.

Cut the admin burden of managing a fragmented system

One admin portal for all users, numbers and call flows. Over 500 integrations — including Salesforce, HubSpot, Microsoft 365 and Zoho. Native Microsoft Entra ID integration means adding a user in RingCentral automatically provisions their access to everything they need.

What to evaluate before choosing a platform

Before shortlisting UCaaS vendors, build your criteria around what your team actually needs to operate reliably.

How much does UCaaS cost in Australia?

RingEX pricing follows a per-user, per-month model. Costs vary by tier and feature set, typically ranging from around $15 to $45 AUD per user per month.

A few things to understand before comparing prices:

• Entry tiers cover core calling, messaging and video
• Mid tiers add call recording, analytics and reporting
• Enterprise tiers include AI features, expanded compliance controls and priority support
• The headline price rarely tells the full story — international calling rates, add-on features and premium integrations carry additional costs

Request an itemised quote that covers everything your team needs on day one, not just the base licence.

It's also worth factoring in what you're currently spending on separate tools. Businesses that consolidate onto RingCentral typically reduce the number of vendors they manage and eliminate redundant licences.

How RingCentral RingEX delivers on UCaaS

RingCentral RingEX is the cloud-based business communications platform that gives every employee calling, messaging and video from anywhere. The same business number, extension and setup follow people wherever they're working — without separate infrastructure for each location or hardware delays for new starters.

It's built on 99.999% uptime infrastructure, which translates to less than six minutes of downtime per year. It integrates natively with Microsoft Teams, Slack, Salesforce, HubSpot and more than 500 other applications. And its AI suite — AIR, ACE and the Personal AI Assistant — runs natively across every channel, not through third-party integrations that create data silos.

At Kaizn, we offer RingEX as part of Kaizn Essentials — our service line for businesses looking to consolidate back office communications alongside their contact centre setup. We're a RingCentral partner, and one of several technology partners we work with across ANZ. We recommend it when it genuinely fits the problem.

Is RingEX right for your business?

RingEX is not the right answer for every situation. The fit depends on your setup, your industry, your team structure, and where communications is actually costing you.

It tends to be the right conversation when:

• Your contact centre platform is working well but the rest of the business hasn't caught up
• You're running multiple offices on separate phone systems
• Your team is hybrid or distributed and desk phones are creating friction
• You're spending IT time managing a stack of disconnected tools
• You're in a regulated industry and need better visibility and compliance monitoring across calls

If you're not sure whether it fits, that's exactly the conversation we're set up to have.
