Cloud Phone Systems
Technicalities has been deploying and managing cloud phone systems for many years — and the vast majority of our customers run on either 3CX or Microsoft Teams Phone. Both are platforms we know deeply, support daily, and deploy with confidence across businesses of all sizes.
Moving from a traditional phone system to a cloud-hosted platform removes legacy PBX hardware, dramatically reduces line rental and call costs, and gives your team the flexibility to communicate from anywhere — on a desk phone, a computer, or a mobile device.
We work almost exclusively with 3CX and Microsoft Teams Phone — the two platforms that deliver the best outcomes for Australian businesses. Rather than spreading our expertise thin across every VoIP product on the market, we go deep on the platforms that matter most and support them exceptionally well.
Two platforms. Deep expertise in both. The right one for your business depends on your size, your Microsoft 365 environment, and how your team communicates.
3CX
Primary VoIP Platform3CX is our primary VoIP deployment platform and the system we recommend for most businesses. It’s a full-featured, software-based phone system that runs on-premises, in the cloud, or hosted by Technicalities — giving you flexibility without sacrificing control or call quality.
- Full PBX features — auto attendant, queues, voicemail, call recording
- Desktop and mobile apps so staff can work from anywhere
- Web conferencing and live chat built in
- Integrates with Microsoft 365, CRMs, and business applications
- Highly cost-effective — significantly lower than traditional PBX or many hosted alternatives
- Hosted by Technicalities or self-hosted — your choice
Microsoft Teams Phone
For Microsoft 365 EnvironmentsFor businesses already running Microsoft 365, Teams Phone is a good choice — turning the Teams app your staff already use into a full business phone system with direct calling capabilities. One platform for calls, chat, meetings, and file collaboration.
- Native integration with Microsoft 365 — no separate app required
- Make and receive external calls directly within Teams
- Single platform for voice, video, chat, and collaboration
- Managed through the same Microsoft 365 admin environment
- Scales easily as your Microsoft 365 licensing evolves
- Ideal for remote and hybrid teams already living in Teams
Supporting Other Systems — Avaya and Beyond
While 3CX and Teams Phone cover the vast majority of our deployments, we also support customers running Avaya and other legacy or specialised phone systems. If your business has an existing system that isn’t going anywhere, we can manage and support it — and when you’re ready to migrate, we’ll help you do that too.
Deep expertise in 3CX and Microsoft Teams Phone — the two platforms that matter most.
Not a jack of all trades. Genuinely good at what we focus on.Legacy PBX systems are expensive to maintain, difficult to scale, and increasingly inadequate for the way modern teams communicate. Cloud phone systems solve all of that.
Significantly Lower Costs
No expensive PBX hardware to purchase or maintain. Lower call costs and no per-line rental fees for unused capacity — cloud phone systems deliver ongoing savings from day one.
Work From Anywhere
Take calls on a desk phone, a softphone app on your computer, or your mobile — using the same business number wherever your team is working.
Easy to Scale
Add or remove users in minutes — no hardware to provision, no cabling to run, no capacity limits tied to physical infrastructure at your premises.
Multi-Site Simplicity
Connect multiple offices under a single phone system with shared extensions, call transfers, and unified voicemail — no separate systems or contracts per location.
Always Up to Date
Cloud phone systems receive continuous feature updates and security patches — without requiring you to replace hardware or engage a specialist every time something changes.
Better Call Quality
Modern cloud VoIP — particularly on a well-managed network — delivers clear, reliable call quality that equals or exceeds what legacy systems could provide.
Expertise
Years of hands-on experience deploying and managing 3CX and Teams Phone across businesses of all sizes — we know these platforms inside out.
Cost Effective
Competitive deployment and support pricing, with ongoing savings on call costs and the elimination of legacy hardware maintenance contracts.
Customised Solution
We design your phone system around how your team actually works — not a generic out-of-the-box configuration — and integrate it with the rest of your IT environment.
Ongoing Support
We don’t just deploy and disappear. Our team manages and supports your phone system as part of your broader IT environment — one provider, one point of contact.
