Phone Systems Shouldn't Be This Complicated

We hear the same frustrations from business owners every week. Their phone system is outdated, unreliable, or cobbled together from multiple providers. Calls drop, video meetings freeze, and no one knows who to call when something goes wrong. Sound familiar?

  • Your Phone System Is Holding You Back

    Old PBX systems are expensive to maintain, difficult to scale, and impossible to use from home. Every dropped call, missed voicemail, or failed conference is a missed opportunity — and it's costing your business more than you realise.

  • You're Not Sure What You Actually Need

    Teams Phone? SIP trunking? On-premise PBX? Cloud-hosted? The options are overwhelming, and every provider seems to speak a different language. You just want phones that work and video meetings that don't freeze — without needing a telecommunications degree to set it up.

  • Communication Should Be Effortless

    Your team shouldn't have to think about how they make a call or join a meeting. Whether they're in the office, at home, or on the road, business communication should just work — reliably, clearly, and simply.

We've Upgraded Hundreds of Businesses

At Otaris, we've helped businesses across Adelaide and Australia move from outdated phone systems to modern, cloud-based communications. We handle the entire process — from choosing the right platform and hardware to porting your numbers, configuring call flows, and training your team.

We don't just sell you a phone system and walk away. We manage it as part of your IT environment, which means one team handles your phones, your network, your security, and your support. No finger-pointing between providers, no separate bills for separate systems — just one relationship that covers everything.

  • Fully Managed

    We set up, configure, monitor, and support your phone system as part of your IT plan. No separate contracts or providers.

  • Adelaide-Based Support

    When something isn't working, you call your team — the same people who manage the rest of your IT.

  • Legacy Migration Experts

    We've migrated businesses from old on-premise PBX systems to modern cloud platforms with zero downtime.

  • Flexible Options

    Unlimited call plans or pay-as-you-go — we match the plan to how your business actually uses the phone.

Everything Your Business Needs to Communicate

We build your communication system around how your team actually works. Whether you need desk phones, video conferencing, mobile access, or all three — we design, deploy, and manage the whole thing.

  • Your Phone System, Built Into Teams

    Microsoft Teams Phone turns the collaboration tool your team already uses into a full business phone system. Make and receive calls from your desk, laptop, or mobile — using your business number. Features include call queuing, voicemail, auto-attendant, call forwarding, and call recording. It integrates natively with Outlook, SharePoint, and the rest of Microsoft 365, so your communications and productivity tools work as one.

  • Flexible Call Plans That Fit Your Usage

    We provide SIP trunking with your choice of unlimited call plans (local, national, and mobile) or pay-as-you-go options — so you only pay for what you use. We handle number porting, configuration, and ongoing management. Whether you're a team of five making a handful of calls a day or a busy office with phones ringing constantly, we match the plan to your business.

  • A Proven Platform for Businesses That Need More

    For businesses that need a full-featured PBX with advanced call routing, queuing, and contact centre capabilities, we deploy and manage 3CX. It can run on-premise or in the cloud, giving you flexibility without complexity. 3CX includes integrated voice, video, messaging, and live chat — plus mobile apps so your team stays connected from anywhere.

  • Professional Desk Phones, Fully Integrated

    The Yealink MP54 is a premium Teams-certified desk phone with a colour touchscreen, HD audio, and a design built for modern offices. We configure and deploy every handset so it's ready to use out of the box — paired with your Teams or 3CX system, logged in to the right user, and connected to your network.

  • Boardroom Conferencing, Done Properly

    Transform your meeting rooms with Yealink MeetingBoard — a large-format interactive display with built-in camera, microphone, and wireless content sharing. Combined with a touch control panel, expansion microphones, and PTZ cameras, it delivers a professional, high-quality video conferencing experience. We design, install, and manage the entire room setup so your team can walk in and start a meeting with one tap.

  • Video Meetings That Actually Work

    Whether it's a quick one-on-one or a company-wide meeting with 250 participants, we set up video conferencing that's reliable and simple. Screen sharing, meeting recording, breakout rooms, and live captions are all included with Microsoft Teams. We configure everything so your team can join meetings from any device — desktop, laptop, tablet, or phone — without IT support.

Why Your Phone System Should Be Part of Your IT

  • Separate phone provider

    When calls drop, you call one company. When the network goes down, you call another. They blame each other.

    One team manages your phones, your network, and your IT. When something goes wrong, we fix it — no finger-pointing.

  • Separate phone provider

    Your phone system doesn't talk to your email, calendar, or collaboration tools.

    Your phone system is built into Microsoft Teams — so calls, meetings, chat, and files all live in one place.

  • Separate phone provider

    You manage a separate contract, a separate bill, and a separate support number.

    Your phone system is included in your IT plan. One relationship, one invoice, one team to call.
