Should You Switch Your Business Phone System to Microsoft Teams?

Moving from a traditional phone system to Microsoft Teams Phone can cut costs and simplify how your team communicates. Here's what to consider before you make the change.

The Problem With Keeping Your Old Phone System

Most businesses still run a separate phone system alongside their computers. You have a desk phone, a Teams app on your laptop, and maybe a mobile number. Your IT team manages the phone system independently. When someone leaves or joins, there's another ticket to process. When you move offices, the cabling and setup take time and money.

It works, but it's expensive to maintain and it fragments how your team actually communicates.

Microsoft Teams Phone changes that. It brings calling into the Teams app you already use every day. No separate handset. No separate bill line. One platform for chat, video, and voice.

Cost Savings That Add Up

A traditional phone system requires hardware, ongoing maintenance, and a separate monthly bill. When you scale to Teams Phone, you move to a per-user licence model. You pay only for the people who need it.

Removing the hardware means no repair costs. No technician visits to fix a phone line. No replacement units when something fails. For a business with 30 to 50 staff, that's a real saving each month.

Adding a new employee is simpler too. Assign them a Teams licence and they have a phone number immediately. No waiting for physical setup.

Reliability You Can Actually Depend On

Your phone system has to work. If it goes down, customers can't reach you and your team can't reach clients.

Microsoft Teams Phone runs on Microsoft's infrastructure and comes with a 99.999% uptime guarantee backed by a Service Level Agreement. That's less than five minutes of downtime per year. If Microsoft fails to meet that target, you get service credits.

This matters because Teams Phone works as long as your internet connection does. If you already have reliable broadband to your office, your phone system is already reliable.

Calling Built Into The Tool Your Team Already Uses

Your staff spend their day in Teams anyway. Chat, video calls, file sharing. Adding phone calls to the same app means one less thing to learn and one less app to switch between.

Making a call is just clicking a contact name. Receiving a call appears as a Teams notification. You can take it on your desktop, transfer it to your mobile, or put it on hold while you grab a document.

For IT teams, management happens in the same admin centre where you already manage Teams. You don't need to log into a separate phone system portal.

Staying Connected Across Locations

If your team works from the office, home, or client sites, Teams Phone keeps everyone reachable. A call to your business number rings on your phone, your laptop, and your mobile simultaneously, wherever you are.

Your staff can answer from any device. A tradesperson on a job site can take a call on their mobile. An office worker can switch from their desk to their laptop when they move to a meeting room.

This flexibility matters when you're running a business across the Waikato or the Bay of Plenty with people working from different locations.

Security and Compliance Built In

Phone calls can include sensitive information: client details, contract terms, payment information. Teams Phone uses end-to-end encryption for calls. Data is protected in transit and at rest.

Microsoft also maintains compliance with industry standards. If your business operates in a regulated sector, Teams Phone is designed to meet those requirements.

Growing Without Ripping Out Infrastructure

As your business adds staff, adding phone capacity is straightforward. Assign a new Teams Phone licence and the user has a number. No hardware to order. No installation delays.

This scales in both directions. If you downsize, you simply remove the licence. You're not stuck with equipment you no longer need.

Keeping Operations Running Through Disruptions

A major storm, flooding, or other event that closes your office doesn't have to stop your team from working. As long as they have internet access, they can make and receive calls from home or anywhere else.

Your phone system doesn't depend on a physical location or a single point of failure. Your business continuity improves automatically.

Is It Right For Your Business?

Teams Phone works best if your team already uses Microsoft 365 or Teams. If you're still on older email systems or have specific phone features your current system provides, the migration takes more planning.

The right decision depends on your current setup, the size of your team, and how your people work. A business with five staff in one office has different needs from a firm with 50 people spread across multiple locations.

If you're running a traditional phone system and paying a separate monthly bill for it, there's a real opportunity to consolidate. You'll cut costs, reduce the number of systems your IT team manages, and give your staff a simpler way to stay connected.

We can help you figure out whether Teams Phone makes sense for your business and handle the migration if it does. Get in touch and we'll walk through your current setup and what the change would look like for you.

5 Microsoft 365 Settings Worth Checking in Your Tenant

Microsoft has tightened several Microsoft 365 defaults over the past few years, but those changes do not always apply retroactively. Tenants set up before 2022, or configured by a previous IT provider and left alone since, often still have legacy settings in place around file sharing, external email forwarding, third-party app consent, audit log retention, and MFA enforcement. Five settings worth verifying.

Why Bad Onboarding Is the Real Cause of Messy Offboarding

Offboarding is the final step of a process that started on the employee's first day. Shared logins, forgotten SaaS subscriptions, untracked personal devices, and client relationships locked inside one person's inbox are almost always traceable to informal onboarding shortcuts taken months earlier. Tightening the onboarding side turns each future departure into a 90-minute checklist instead of a three-week cleanup.

How to Prepare Microsoft 365 Permissions for a Safe Copilot Rollout

Microsoft 365 Copilot retrieves files, emails, and chats using each user's existing Microsoft 365 permissions. In most tenants, those permissions are broader than anyone has mapped, because access accumulates across years of projects and staff changes. A safe Copilot rollout begins with auditing those permissions, fixing the gaps, and applying sensitivity labels to confidential content. Microsoft publishes specific guidance on this cleanup, structured into a pilot, deploy, and operate sequence.
