VoIP phone systems for Perth businesses
Voice and video calls can now run on the same network as your email and web traffic. A VoIP phone system is cheaper to run than a separate phone service, and call quality is better when a dedicated IT provider manages it. No more old in-house systems nobody supports, or staff who can’t take calls on the road. Zetta sets it up as part of your managed IT service, so that’s one less vendor to worry about.

30-min critical response
Microsoft Teams integration
Built on Microsoft, with Teams calling on a network we manage
Your phone system is part of your IT. Treat it like it.
Keep you connected
When calls, chat and video are spread across different providers, it gets costly and confusing. Integrating VoIP with Microsoft Teams gives you one place for every call, message and meeting, and our Microsoft 365 management brings your IT and comms together.
Keep you running
An unreliable phone system means missed calls and missed business. A managed VoIP system is monitored continuously for network and call quality, so most issues are fixed before they cause a problem.
Keep you supported
With VoIP-only or telco providers there is no single number to call, so you get bounced between phone vendors and IT providers. With Zetta it is one team and one number for every issue, with guaranteed response times.
What’s included when Zetta manages your phone system
Network management
Good call quality depends on good networking. We monitor continuously for reliable performance, with one number to call for any phone, chat, video or IT issue.
Vendor management
We handle number porting, carriers and hardware for you, and deliver the right equipment, set up correctly, for a reliable integrated phone system.
Teams and collaboration
Depending on how you use Microsoft 365, we integrate your VoIP phones into Microsoft Teams and your other workplace systems.
Service desk
One number to call for handset issues, call routing changes and voicemail setup.
Your monthly fee covers business as usual support. Office moves, server migrations and new site rollouts are scoped separately as projects. Pricing excludes hardware and software licensing (for example Microsoft 365).
If your phones go down, we treat it like your business is down
Our SLA is not small print, it is a commitment. When the phones are down the business is down, so critical issues carry a guaranteed 30-minute response. Call quality and system monitoring run continuously in the background to keep you connected.

Frequently asked questions about VoIP phone systems
What is a VoIP phone system?
VoIP stands for Voice over Internet Protocol. Your business calls run over your internet connection instead of a traditional phone line, through a handset, a computer or a mobile app, and it integrates neatly with platforms like Microsoft Teams.
Do we need to buy new hardware?
Not necessarily. VoIP works with dedicated handsets or through software on a computer or mobile. We recommend the right mix based on how your team actually works.
What happens to our phones if the internet goes down?
Reliable VoIP comes down to resilience planning. Calls fail over to cellular or an alternative service when that is set up in advance, and we cover a backup plan for both internet and power so your phones stay connected.
Can we keep our existing business phone number?
Yes. Number porting is standard when moving to a managed VoIP system, and we handle the whole process with your current provider on your behalf.
Is VoIP call quality actually reliable for a business?
Yes. On a properly set up connection, call quality now matches or beats old copper lines. Quality depends on the network underneath, which is why we manage the network and monitor call performance rather than leaving it to chance.
How does VoIP work with Microsoft Teams?
Calls can be integrated directly into Teams, so calls, chat and meetings sit in one place instead of separate apps. We advise the best fit for your current Microsoft 365 setup.
How is this different from buying a VoIP plan from a telco?
A telco sells you a phone line. We manage the whole system: the network underneath it, the handsets, the call flows, and ongoing support for staff changes and requests, all from the same team that looks after your IT.
