Conference season is officially in full swing across Victoria!

At Zero 3 Communications, supporting our local school leadership networks is at the heart of what we do. We’ve been proud to hit the road recently to connect with the incredible teams at the:

- Riversdale Principals Conference
- Merri-bek Principals Conference
- North Eastern Business Managers Network

Across these three regions alone, Zero 3 currently supports around 85% of the schools in attendance. Providing reliable VoIP systems and tailored connectivity solutions that help Victorian schools stay connected is a responsibility we take great pride in.

These events are a fantastic opportunity for us to give back to the communities that have supported us for 15 years. If you spot the Zero 3 crew out and about at a conference or school network meeting, please come and say hello. We always appreciate a chat, whether it's for technical feedback or just to hear how things are going at your school.

See you there!

Heads up, Victoria! 📢

There is a nationwide test of Australia’s new emergency warning system, AusAlert, coming up on Monday, 27 July 2026, at 2:00 PM (AEST).

If you’re in a meeting, a classroom, or just trying to get some focus time, be prepared: compatible mobile phones, tablets, and smartwatches will sound a loud siren and display a test message. This happens even if your device is switched to silent.

The good news? No action is required from you. It’s simply a test to ensure the system is ready to protect us during real emergencies like bushfires or floods.

We wanted to make sure our schools and business partners weren’t caught off guard by the noise!

You can find more details and official info here: www.ausalert.gov.au/alerts-explained/national-test

Stay connected and stay safe.

Fifteen years ago, we started Zero 3 Communications with a simple goal: to help Victorian organisations stay connected. Today, we’re celebrating our 15th anniversary, and it’s a great time to look back at how far the technology: and our company: has come.

Since 2011, we’ve seen the industry shift from traditional copper lines to the advanced cloud and VoIP systems we support today. Throughout all those changes, our focus has remained on providing reliable, tailored solutions for Victorian schools and businesses.

We want to share a big thank you with our team of technicians and support staff, as well as our clients who have been with us on this journey. Your trust is what allows us to keep doing what we love: solving communication challenges and ensuring your teams stay connected, whether they are in the office or working remotely.

Whether you’ve been with us since day one or you’re a newer partner, thank you for being part of the Zero 3 story. We’re looking forward to many more years of supporting the Victorian community with scalable, modern communication infrastructure.

No one likes being left in the dark when a network outage happens. At Zero 3 Communications, we believe transparency is just as important as the connection itself.

That’s why we’ve launched our new, real-time Status Page.

Whether it’s a planned maintenance window or an unexpected service blip, you can now get instant visibility into our systems and network health. No more guessing: just clear, up-to-the-minute information whenever you need it.

We highly recommend heading over to status.zero3.net.au and hitting the "Subscribe" button. By doing this, you’ll receive instant updates via email the moment anything changes, ensuring your team or school stays informed and prepared.

It’s all part of our commitment to making business communications easy and keeping Victorian organisations reliably connected.

Is your phone system still living in the past?

Now that daylight savings has wrapped up, it’s the perfect time for a quick system check. While most of our VoIP setups handle the time change automatically, older hardware or specific server settings can occasionally miss the memo.

It’s more than just a wrong number on a screen. If your system clock is out of sync, your automated call routing, time-of-day schedules, and voicemail timestamps could all be lagging behind.

At Zero3, we don’t just set and forget. Our Zero3 Care maintenance covers the small details that keep your business running smoothly, including:
- Routine system backups to keep your data safe.
- Essential firmware and security updates.
- Full connectivity and hardware health checks.

If your handsets are showing the wrong time or your 'after-hours' greeting is kicking in at the wrong hour, let us know. We’ll jump in and get everything lined up.

Keep it simple, keep it accurate.

Is your old tech gathering dust in the office storage cupboard? It could be a literal lifeline for someone in need.

This May, Zero 3 Communications is proud to support the "Pass the Phone Challenge" for DV Safe Phone and Rotary International. We’re calling on our community of Victorian schools and businesses to dig out those retired mobile handsets, laptops, and devices.

What happens to your donation?
Instead of heading to e-waste, every device we receive goes through a secure process. They are professionally wiped and factory reset to protect your data before being repurposed. These phones are then gifted to victims of domestic violence, providing them with a safe, reliable way to call for help and stay connected to support networks when it matters most.

Domestic & Family Violence Prevention Month is about taking practical action. Help us turn unused hardware into a safety net.

If your school or business wants to host a phone drive or learn how to donate, reach out to us today. Let’s make a difference together this May.

Is your school still using Optus DirectLine services? It is time to look at the roadmap ahead.

Optus has announced that DirectLine services will reach end-of-life on 15 May 2027. While that might feel far away, Victorian schools were encouraged to confirm their future direction by January 2026 to ensure a seamless transition. If you haven't finalised your plan yet, now is the right time to start the conversation.

Proactive planning prevents a last-minute rush as the final cutoff approaches. At Zero 3 Communications, we are helping schools across Victoria navigate these changes without the technical jargon.

We can help your school:
- Understand the impact on your current setup.
- Review existing hardware and cabling requirements.
- Map out a migration path that fits your budget and timeline.

Our goal is to ensure your school stays reliably connected with modern, scalable solutions. If you are unsure about your next steps, our team is here to support you.

Call us on 1300 01 03 03 or email [email protected] to start your transition plan.

Ever wonder why some clients or parents aren't picking up your calls? It might be because your business number is showing up as "Spam" or "Fraud" on their screens.

This is a common headache, especially for Victorian schools and medical centres that make a high volume of outbound calls. The good news? It’s usually not a fault with your phone system: it’s how apps like Truecaller and Hiya identify your number. These apps rely on user reports and internet data, which can sometimes be incorrect.

Here’s how you can fix it:

1. Update Truecaller: Visit their unlisting page (https://www.truecaller.com/unlisting) and verify your phone number via SMS.
2. Notify Hiya: Submit a request via their help desk (https://hiyahelp.zendesk.com/hc/en-us/requests/new?ticket_form_id=824667) to correct an "Incorrect Caller ID" label.
3. Sync Your Online Listings: Make sure your number matches perfectly on your website and Google Business Profile.

Updates usually take between 1 to 7 days to kick in. If you’re a Zero 3 Communications customer and need a hand navigating these technical hurdles, give us a shout. We’re here to make sure your calls actually get through.

Supporting Victorian schools with reliable communications.

At Zero 3 Communications, we’ve built a reputation as a leading provider for Victorian Government Schools. We understand that school environments require more than just a phone line: they need a seamless connection between staff, students, and the community.

But don’t just take our word for it. Here is what some of our local school partners have to say:

"Alicia and the whole team made things super easy and everything went incredibly smoothly. Couldn't ask for a better experience." : Bradley Mills, Frankston Primary School.

"Mark was great over the phone running through troubleshooting steps. Quick, patient, and knew exactly what needed to be done!" : Zachary Brew, St Marys Primary School.

Whether it’s a full system migration or ongoing technical support, we’re here to ensure your school stays connected without the stress.
