Microsoft Teams Phone Pricing Australia: Calling Plans, Direct Routing, and Hidden Costs

Microsoft Teams Phone in Australia costs significantly more than the headline add-on price suggests. This guide breaks down every licensing layer you need to pay for, the real per-minute and per-user costs of calling plans versus Direct Routing, and the hidden expenses that most articles and MSPs never mention. By the end, you will have a clear picture of what a 10-seat Teams Phone setup actually costs in Australia and when a dedicated VOIP provider is the smarter call.

There is a persistent belief in the small business market that if you already pay for Microsoft 365, adding phone calls to Teams is almost free. It is not. Teams Phone involves stacking multiple licensing tiers, choosing a calling architecture, and absorbing several costs that Microsoft's own documentation buries. Australian businesses face additional wrinkles: Microsoft's Calling Plans have limited domestic rate packages here, number porting to Microsoft is slow and complex, and the PSTN copper shutdown means the timing matters more than ever.

Prices cited in this guide are AUD and reflect published Microsoft and provider rates as of early 2026. Microsoft licensing prices change periodically. Always verify current pricing at Microsoft's AU pricing page before committing.

The Licensing Stack: What You Are Actually Paying For

Teams Phone is not a single product with a single price. It is an assembly of three distinct licensing layers. You need all three for a user to make and receive real phone calls through Teams.

Layer 1: Microsoft 365 Base Licence

Every user who needs Teams Phone must have a Microsoft 365 licence that includes Teams. The most common tiers for small business in Australia are:

• Microsoft 365 Business Basic: approximately $9.40/user/month. Includes Teams, Exchange Online (email), SharePoint, and OneDrive. Does not include desktop Office apps (Word, Excel, PowerPoint installed locally). Sufficient for Teams Phone from a licensing standpoint.
• Microsoft 365 Business Standard: approximately $18.70/user/month. Adds desktop Office apps, webinars, and Bookings. Most SMBs who need the Office apps land here.
• Microsoft 365 Business Premium: approximately $31.10/user/month. Adds advanced security (Defender for Business, Intune). Relevant for regulated industries or businesses with stricter security requirements.

If your team is already on Microsoft 365 for email and Office apps, you are already paying Layer 1. But if you are evaluating Teams Phone from scratch, this is your baseline cost before phone calls exist.

Layer 2: Teams Phone Standard Add-On

Microsoft 365 Business plans include Teams for meetings and chat, but they do not include the PBX features needed to connect to the public phone network. For that, you need the Teams Phone Standard add-on, priced at approximately $8.00/user/month in Australia (verify current pricing at Microsoft's AU site).

What Teams Phone Standard gives you:

• Cloud-based PBX features: auto-attendants, call queues, voicemail, hold music
• The ability to connect a calling plan or Direct Routing provider
• Emergency calling configuration

What it does not give you:

• Actual phone calls to external numbers. That is Layer 3.

This is where many businesses get a surprise. They pay for Teams Phone Standard thinking they are done, then discover they still cannot call a customer's mobile or landline without adding a calling plan.

Layer 3: The Calling Architecture (Calling Plan or Direct Routing)

Layer 3 is where the real cost and complexity decisions happen. There are three options for connecting Teams to the public telephone network in Australia: Microsoft Calling Plans, Direct Routing, and Operator Connect.

Option A: Microsoft Calling Plans

Microsoft Calling Plans are Microsoft's own-brand PSTN connectivity product. You buy minutes or a monthly plan directly from Microsoft, and Microsoft handles the carrier relationship. Simple on paper. More complicated in practice for Australian businesses.

Available plans in Australia (as of early 2026):

• Domestic Calling Plan: Approximately $12-15/user/month in Australia. Provides a set number of minutes for calls to Australian landlines and mobiles. Exact inclusions and overage rates vary and Microsoft updates these regularly. Check Microsoft's calling plan documentation for current rates.
• International Calling Plan: Add-on on top of domestic. Pricing varies significantly by destination. Australian SMBs calling Asia-Pacific destinations frequently should model their actual call volumes before committing.
• Pay-as-you-go (metered): No included minutes. Calls billed per minute at Microsoft's published rates. For very low call volumes, this can be cost-effective. For businesses with moderate-to-high call volumes, the per-minute rates can quickly exceed a flat plan.

The honest assessment of Microsoft Calling Plans in Australia: Microsoft's Calling Plan footprint is more mature in the US and UK than in Australia. Domestic per-minute rates are not particularly competitive compared to local VOIP carriers. Number porting to Microsoft (moving your existing phone number) is notoriously slow in Australia. Some businesses have reported 6-8 week waits. If you have a well-known phone number that customers have saved, a long port window is a real business disruption.

Option B: Direct Routing

Direct Routing lets you connect Teams Phone to any SIP-compatible VOIP carrier using a Session Border Controller (SBC). Instead of buying minutes from Microsoft, you buy them from an Australian VOIP provider, routed through an SBC into your Teams environment.

Why businesses choose Direct Routing:

• Access to competitive Australian VOIP carrier rates (typically lower than Microsoft's Calling Plan pricing)
• Ability to keep existing phone numbers with their existing carrier (no Microsoft porting complexity)
• More control over call routing, codec selection, and failover
• 1300/1800 number support is easier to manage through local carriers

What Direct Routing actually costs:

Direct Routing costs are less obvious because they combine several components:

• SBC hardware or managed service: If you run your own SBC (e.g. AudioCodes, Ribbon, Oracle), expect hardware costs from $500-$3,000+ depending on capacity, plus an IT resource to configure and maintain it. This is not a small business option. Most SMBs use a managed SBC service from an Australian provider, which typically costs $50-$200/month depending on capacity and provider. Some VOIP carriers bundle SBC as a managed service.
• VOIP carrier costs: Line rental plus call rates from an Australian SIP trunk provider. Roughly $10-$30/month for line access plus competitive per-minute rates (Australian domestic mobiles typically $0.10-$0.15/minute, landlines lower). Volume plans can reduce these significantly.
• Microsoft Teams Phone Standard add-on still required: $8/user/month per user on top of Direct Routing costs.

For large businesses (50+ seats), Direct Routing usually wins on cost. For 10-20 seat SMBs, the managed SBC cost can erode the savings, particularly when you add the MSP or IT resource needed to manage the configuration.

Option C: Operator Connect

Operator Connect is a middle-ground option. Certified Australian carriers connect directly to Microsoft's network infrastructure, so you get competitive carrier pricing without needing to manage your own SBC. The carrier handles the SBC component on their end.

Operator Connect providers certified in Australia include:

• Telstra
• Optus
• Vonage (via Australian distribution)
• A growing list of smaller certified carriers

Operator Connect simplifies the architecture compared to self-managed Direct Routing, but you are still locked into a Microsoft Teams ecosystem and still paying the Teams Phone Standard add-on per user. Pricing varies by carrier. Telstra's Operator Connect pricing, for example, is not designed for 5-10 seat SMBs. The economics improve at scale.

Hidden Costs Most Articles Do Not Mention

The base licensing stack (M365 + Teams Phone Standard + calling plan) is the visible cost. Here is what does not make the headline numbers:

Meeting Room Licensing

If you want Teams Phone in a boardroom or meeting room, you cannot use a standard Teams Phone Standard licence. You need a Teams Rooms licence, which ranges from approximately $7/room/month (Teams Rooms Basic, limited features) to $18/room/month (Teams Rooms Pro, full management and analytics). Each physical meeting room requires its own licence. A business with 3 meeting rooms is adding $21-$54/month before any hardware.

Desk Phone Hardware

Teams-certified desk phones (Yealink MP series, Poly CCX series, AudioCodes C450HD) cost significantly more than equivalent standard SIP phones. A Teams-certified desk phone typically runs $300-$600+ per unit in Australia, compared to $150-$300 for a standard SIP phone that works with any VOIP provider. The ecosystem lock-in has a hardware cost attached to it.

Alternatively, businesses can use Teams as a softphone on laptops and mobiles (with the Teams app), or add USB headsets for call centre-style use. This avoids hardware cost but requires users to be at their computer to take calls.

Number Porting Fees and Complexity

Porting your existing phone number to Microsoft Calling Plans involves Microsoft's carrier process, which in Australia can take 4-8 weeks. During that window, businesses typically need to maintain their existing service, meaning they are paying for two phone services simultaneously. Some carriers charge porting-out fees on the originating side ($30-$100 per number is common). Microsoft also does not support porting of 1300 numbers into Calling Plans.

Emergency Calling Configuration

Teams Phone requires explicit emergency calling address configuration in Australia. This is not automatic. If your deployment uses Direct Routing, your SBC provider must support dynamic emergency calling. Misconfigured or untested emergency calling (000) is a compliance risk and a safety risk. Allow setup time and, if using an MSP, confirm they have tested it explicitly.

MSP Margin and Setup Fees

Many Australian businesses deploy Teams Phone through a Managed Service Provider. MSPs often make margin on the Microsoft licensing stack itself (they resell Microsoft 365 licences at a markup). This creates an incentive to recommend Teams Phone even when it is not the most cost-effective option for an SMB. Setup fees for Teams Phone deployments are commonly $500-$3,000+ depending on complexity. Ongoing management adds another layer. Not all MSPs explain the full cost picture upfront.

1300 Number Limitations

Microsoft Calling Plans do not support 1300 or 1800 numbers in Australia. If your business uses a 1300 number as its main inbound line, you cannot port that number to a Microsoft Calling Plan. You will need to either keep a separate VOIP service for 1300 handling and forward calls to Teams, or use Direct Routing or Operator Connect with a carrier that supports 1300. This is a significant gap for Australian SMBs where 1300 numbers are common as the customer-facing number.

Total Cost Comparison: 10-Seat Teams Phone vs 10-Seat Hosted VOIP

Here is a realistic cost model for a 10-person business considering both options. Assumes the business already has Microsoft 365 Business Standard licences for productivity (email, Office apps). Teams Phone cost is the incremental cost on top of existing M365 spend.

Scenario A: 10-seat Teams Phone (Calling Plan)

• Teams Phone Standard add-on: $8 x 10 = $80/month
• Microsoft Domestic Calling Plan: ~$13 x 10 = $130/month
• Setup and porting (amortised 12 months): ~$50-100/month
• Total incremental cost: $260-310/month

This excludes Teams-certified hardware (one-off cost of $3,000-$6,000 for 10 desk phones if replacing existing handsets). It also excludes 1300 number handling, which would require a separate service and additional cost if the business has a 1300 number.

Scenario B: 10-seat hosted VOIP (specialist Australian provider)

• Hosted PBX plan including per-user lines: ~$15-25 x 10 = $150-250/month
• 1300 number included (most providers): $0-$20/month additional
• Setup: typically $0-$200 one-off (most specialist providers include it)
• Standard SIP desk phones (if needed, one-off): $1,500-$3,000 for 10 units
• Total monthly cost: $150-270/month

The hosted VOIP option typically costs less per month, does not require M365 stack as a prerequisite, includes 1300 support, and has simpler porting. Hardware is cheaper if you need physical phones. The trade-off: you lose the Teams integration (calls appear in a separate app, not in Teams).

The real question is not just cost but workflow: If your team lives in Teams all day and wants calls appearing in the same interface, the Teams integration has genuine value. If your team uses Teams for meetings but takes calls separately, the integration benefit is much weaker and the cost premium is harder to justify.

When Teams Phone Makes Sense vs When It Does Not

Teams Phone is worth the cost when:

• Your team is already deeply embedded in Microsoft 365 and spends most of their day in Teams
• You have 20+ seats, where the per-unit costs become more manageable and Direct Routing economics improve
• You need advanced PBX features tightly integrated with Microsoft ecosystem (contact centre, CRM integration via Dynamics, complex call routing)
• You have an IT team or MSP who can manage the configuration and ongoing compliance
• You are not relying on a 1300 number as your primary inbound line

A dedicated VOIP provider is usually better when:

• You have 1-20 seats and are primarily looking for cost-effective calls
• You have or want a 1300 number as your main customer-facing line
• Your team does not live in Teams day-to-day (you use Teams for video meetings but not as a work hub)
• You want simpler setup, faster porting, and a single provider to call when something goes wrong
• Budget is a primary concern and you cannot absorb the Microsoft licensing layers

The pattern that plays out regularly: an SMB pays for Teams, then discovers Teams Phone requires additional licensing, then discovers the Calling Plan does not support their 1300 number, then ends up paying for both Teams Phone and a separate VOIP service. Two monthly bills, two admin burdens, no integration benefit. This is avoidable with the right information upfront.

Australian-Specific Realities for Teams Phone

NBN and call quality: Teams Phone calls run over your internet connection. NBN quality matters. On an NBN HFC or FTTP connection with adequate upload speed (minimum 5Mbps upload for reliable simultaneous calls), Teams Phone call quality is generally acceptable. On older NBN technologies or connections with high jitter and packet loss, call quality degrades. Teams uses adaptive codecs that can compensate to a degree, but a poor NBN connection will produce poor call quality regardless of which phone system you use.

Number porting to Microsoft is slow: Australian PSTN number porting to Microsoft's Calling Plan infrastructure is handled through Microsoft's carrier agreements, which involve additional intermediaries compared to porting between local VOIP carriers. Realistic timelines are 4-8 weeks. Plan for this if you are moving an existing business number.

PSTN copper shutdown: Australia's copper PSTN switched off in 2025. All business phone calls now travel over VOIP infrastructure at the network level, whether you realise it or not. This means the underlying technology argument between VOIP and traditional phones is resolved. The question is which VOIP infrastructure you use and who controls it.

ACMA and Australian number regulations: Australian phone number regulations (ACMA's Numbering Plan) apply to Teams Phone deployments. If you are using Australian geographic numbers or 1300/1800 numbers, standard ACMA rules apply to porting, geographic number assignment, and usage. Teams Phone deployments that use Direct Routing or Operator Connect with Australian carriers operate under the same regulatory framework as any VOIP deployment.

What Most Businesses Get Wrong with Teams Phone Pricing

Mistake 1: Assuming Teams Phone is nearly free if you already pay for Microsoft 365. The Teams Phone Standard add-on ($8/user/month) plus a Calling Plan ($12-15/user/month) is $20-23/user/month on top of your existing Microsoft 365 licence. For a 10-seat team, that is $200-230/month in additional spend before any hardware, setup, or 1300 number considerations. It is not free. It is not even close to free.

Mistake 2: Not checking 1300 support before committing. Microsoft Calling Plans do not support 1300 numbers in Australia. If your business has a 1300 number, you discover this after paying for Teams Phone Standard and a Calling Plan licence. The workaround (keeping a separate carrier for 1300 with call forwarding into Teams) adds cost and complexity that defeats much of the simplicity argument for Teams Phone.

Mistake 3: Taking the MSP recommendation at face value. MSPs often resell Microsoft 365 licences and make margin on the stack. The incentive to recommend Teams Phone exists regardless of whether it is the right fit for a 5-seat business. Ask your MSP to provide a cost comparison with a dedicated VOIP provider before committing. If they cannot or will not, that tells you something.

Your Next Steps Before Committing to Teams Phone

Before signing up for Teams Phone, work through this checklist:

1. Check your 1300 situation. Do you have or want a 1300 number? If yes, confirm with Microsoft or your provider how it will be handled. Do not assume.
2. Count your actual users. Teams Phone Standard is per user. Only count users who actually need to make and receive external phone calls, not everyone on your Microsoft 365 licence.
3. Get a written cost breakdown. Ask your provider or MSP to itemise: base M365 licence, Teams Phone Standard per user, calling plan per user, any SBC fees if using Direct Routing, setup fees, hardware if applicable. Total monthly and annual figures.
4. Model your call volumes. If considering pay-as-you-go calling, estimate actual minutes per user per month based on current call history. Compare against flat plan pricing.
5. Compare against a VOIP-only option. Get a quote from a specialist Australian VOIP provider for the same number of seats. Use our VOIP cost guide as a framework. The comparison often surprises people.
6. Check your NBN connection quality. Run a quality test (not just a speed test) on your connection. High jitter or packet loss will cause call quality problems regardless of which phone system you choose.
7. Ask about porting timelines. If you are moving an existing number, get the expected porting timeline in writing and plan your cutover accordingly.
8. Get a free recommendation if you are not sure. Use our Get a Recommendation page to describe your setup and get a matched recommendation for your business size and call patterns.

Once you have the cost picture clear, the natural next question is whether Teams Phone is the right choice at all. See Microsoft Teams Phone vs Hosted VOIP for a direct comparison of the two approaches for Australian SMBs.

What is the total cost of Teams Phone for a 10-person business in Australia?

A 10-seat Teams Phone deployment using Microsoft Calling Plans typically costs $260-310/month in additional spend on top of existing Microsoft 365 licences. This includes Teams Phone Standard at approximately $8/user/month and a Domestic Calling Plan at approximately $12-15/user/month per user. This excludes hardware (Teams-certified desk phones cost $300-600 each), setup fees, and any 1300 number handling costs (which Microsoft Calling Plans do not support). If you need 1300 support or desk phones, real costs will be higher. Verify current Microsoft pricing as it changes regularly.

Can I use my existing 1300 number with Microsoft Teams Phone?

No, Microsoft Calling Plans in Australia do not support 1300 or 1800 numbers. If your business has a 1300 number, you cannot port it into a Microsoft Calling Plan. Your options are: (1) use Direct Routing or Operator Connect with a certified Australian carrier that supports 1300 numbers, routing calls through an SBC into Teams; or (2) keep your 1300 number with a separate Australian VOIP provider and forward calls to your Teams number. Option 2 means paying for two services. This is one of the most common unexpected limitations Australian SMBs hit with Teams Phone.

What is the difference between Teams Phone Direct Routing and Operator Connect?

Both Direct Routing and Operator Connect let you connect Teams Phone to an Australian phone carrier instead of using Microsoft's own Calling Plans. Direct Routing requires a Session Border Controller (SBC), either hardware you manage yourself or a managed service you rent from a provider, to bridge your carrier's SIP trunk into Teams. Operator Connect uses carriers who have direct certified connections into Microsoft's network, eliminating the need for a customer-managed SBC. Operator Connect is simpler to deploy than self-managed Direct Routing. In Australia, Telstra and Optus offer Operator Connect. Pricing for both options varies by carrier and seat count. Both still require the Teams Phone Standard add-on licence per user.

How long does number porting to Microsoft Teams Phone take in Australia?

Number porting to Microsoft Calling Plans in Australia typically takes 4-8 weeks. This is longer than porting between most local VOIP carriers, which often completes in 5-10 business days. The extended timeline is due to Microsoft's carrier intermediary arrangements in Australia. During the porting window, businesses usually need to maintain their existing phone service, meaning you are paying two bills simultaneously. Plan your cutover timing carefully, especially if you have a well-known number. If porting timeline is a critical factor, Direct Routing or Operator Connect with a local Australian carrier typically offers faster porting.

Do I need Teams Phone Standard if I already have Microsoft 365?

Yes. Microsoft 365 Business plans (Basic, Standard, Premium) include Teams for meetings, chat, and collaboration, but they do not include the PBX features required to connect to the public phone network. The Teams Phone Standard add-on, approximately $8/user/month in Australia, is required for each user who needs to make and receive external phone calls. Without it, Teams users can do video meetings and internal calls, but cannot call or receive calls from external phone numbers, mobiles, or landlines.

Is Teams Phone cheaper than a hosted VOIP solution for a small Australian business?

For most 1-20 seat Australian businesses, a dedicated hosted VOIP provider is less expensive than Teams Phone when you compare total costs. Teams Phone requires stacking a Microsoft 365 base licence, Teams Phone Standard add-on (~$8/user/month), and a calling plan (~$12-15/user/month). A hosted VOIP plan from an Australian specialist provider typically costs $15-25/user/month all-in, includes 1300 number support, has faster porting, and does not require Teams-certified hardware. The cost gap narrows if your business already pays for Microsoft 365 for other reasons and you are only comparing the incremental phone cost. Teams Phone delivers clear value at larger seat counts or when deep Teams integration justifies the premium.

What happens to Teams calls if my NBN goes down?

Teams Phone calls rely entirely on your internet connection. If your NBN drops, outbound and inbound calls stop working until the connection is restored. There is no built-in failover to mobile unless you configure call forwarding in advance. Most business-grade VOIP providers and Teams Phone configurations allow you to set up a mobile failover number, so incoming calls divert to a mobile if the primary connection is unavailable. Configure this before you need it. For businesses where call availability is critical, a mobile failover or secondary internet connection (4G backup) is worth the modest additional cost.
