Microsoft 365 Calling Plans

Microsoft 365 Calling Plans are Microsoft's own way of giving Teams users real phone numbers and minutes to the public network. They are the simplest option to understand, but not always the cheapest for every business. For the full picture on Teams telephony, start with our Microsoft Teams for Office 365 page.

What Is a Microsoft 365 Calling Plan?

A Calling Plan is an add-on licence from Microsoft that turns a Teams user into a phone user. It assigns them a phone number and a monthly bundle of minutes to the Australian public telephone network. Calls between Teams users stay free and separate; the Calling Plan covers the PSTN side.

What's Included

Calling Plans bundle minutes to fixed lines and mobiles, plus the option of international calling. The exact inclusions vary by plan and country, and Microsoft reviews the minute allocations. What matters for planning is that the cost is a fixed per-user monthly fee, so you know your telephony spend before the month starts.

How Billing Works

You pay per user, per month, for the Calling Plan on top of your existing Microsoft 365 licences. Because it is per user, the total bill grows with your headcount. If every staff member is assigned a Calling Plan but only half of them actually call out, you are paying for minutes that go unused — which is why usage matters when you design your rollout.

Who Needs One

Calling Plans make sense for users who genuinely make a lot of calls — sales, support and account teams. For staff who occasionally need to call out, a per-user Calling Plan can be overkill. That is where Operator Connect or a hosted VoIP connection can save money, because you pay for actual usage rather than a licence for every seat.

Calling Plans vs Operator Connect

Microsoft Calling Plans buy minutes and numbers from Microsoft. Operator Connect is the alternative, where a carrier provides numbers and billing and Teams connects to their network. For a deeper comparison of the two and their relative costs, see our Microsoft Teams calling pricing page, and our Teams business voice page for what a complete setup involves.

Frequently Asked Questions

• Do I need a Calling Plan for every user? No. You choose who gets one. Light users can rely on internal calling or be covered by an auto attendant instead.
• What licence do I need first? A Calling Plan requires a compatible Microsoft 365 or Teams licence — check your current tier before adding it.
• Can I keep my existing numbers? Yes, numbers can be ported across so callers keep dialling what they know.
• Is there an alternative if I do not want per-user plans? Yes — Operator Connect bills on usage, which suits variable call patterns.
