Microsoft Teams Phone Australia pricing 2026 — Calling Plans vs Direct Routing

Microsoft Teams Phone is the right answer for most Australian mid-market organisations replacing traditional PBX in 2026. The complication is the licensing model — Microsoft offers four ways to provide PSTN calling to Teams Phone users, and the AUD economics differ by an order of magnitude depending on which one you pick.

The four PSTN models

1. 1Microsoft Calling Plans — Microsoft provides the carrier service in Australia. Per-user-per-month, includes inbound + outbound minutes pool.
2. 2Operator Connect — your existing carrier (Telstra, Optus, AT&T, Vodafone, Lumen, BT) provides the PSTN service; Microsoft handles the integration via the Operator Connect program. Per-carrier-pricing applies.
3. 3Direct Routing — you provide your own Session Border Controller (SBC) and carrier; Microsoft handles only the Teams integration. Most flexibility, most complexity.
4. 4Teams Phone Mobile — bundles a SIM-enabled mobile carrier service through participating providers (Telstra in Australia leading this).

AUD pricing model 1 — Microsoft Calling Plans

Microsoft Calling Plans in Australia ship as add-ons to Teams Phone. The relevant SKUs:

• Teams Phone Standard licence — included in Microsoft 365 E5 ($89.60 AUD/user/month); standalone $13.20 AUD/user/month. This is the platform licence; it does not include PSTN calling.
• Microsoft Calling Plan — $15 AUD/user/month for 120 domestic minute pool, plus per-minute international.
• Teams Phone with Calling Plan bundle — Teams Phone platform + the Calling Plan in one SKU, approximately $28 AUD/user/month.

Pros of Microsoft Calling Plans: single vendor, fast to deploy, no third-party carrier involvement. Cons: pricing is per-user (not per-trunk like traditional PBX), the minute pools rarely match Australian calling profiles, no Number Portability of long-tail DDIs from some legacy AU carriers.

AUD pricing model 2 — Operator Connect (Telstra, Optus)

Operator Connect lets your existing AU carrier provide the PSTN service while Microsoft handles the Teams integration. The carriers offering Operator Connect in Australia in 2026 are Telstra (most extensive), Optus, MyNetFone (Symbio), and TPG-business unit Vocus. Pricing is carrier-specific — typically per-user-per-month for a calling plan plus port-related setup fees. Indicative Telstra pricing ranges $12–25 AUD per user per month depending on minutes pool and existing carrier relationship.

Pros: leverages existing carrier relationship and DDI ranges, minute pricing often better than Microsoft Calling Plans for Australian calling profiles, full Number Portability. Cons: deployment is carrier-managed (timelines vary), feature variance across carriers, requires renewing or restructuring the carrier contract.

AUD pricing model 3 — Direct Routing

Direct Routing is the bring-your-own-everything model. You provide an SBC (Session Border Controller — Audiocodes, Ribbon, AnynodeChrome), you contract with your carrier of choice (any AU carrier; the SBC speaks SIP), and you handle the Teams integration via certified SBC firmware. Microsoft only provides the platform-side integration.

AUD economics: the Teams Phone Standard licence ($13.20 standalone, free in E5) still applies. Add to that: SBC capital cost or hosted SBC service ($300–1,200 AUD/month for a typical AU mid-market deployment), plus per-minute carrier pricing (usually $0.005–0.015 AUD/minute for Australian outbound, free inbound on dedicated DDIs). For a 200-seat organisation with average calling, Direct Routing typically runs $4–8 AUD per user per month all-in — meaningfully less than Calling Plans.

Pros: lowest per-user pricing for high-call-volume profiles, maximum carrier flexibility, no Microsoft dependency for PSTN. Cons: highest deployment complexity, need SBC expertise in-house or via partner, ongoing patch/firmware management.

The decision framework

• Under 50 users, low call volume — Microsoft Calling Plans. Simplest, deploys in days, predictable.
• 50–250 users, existing AU carrier relationship — Operator Connect with Telstra/Optus/Symbio. Leverages the carrier you already trust.
• 100+ users with sophisticated call routing (call centres, IVR, paging) or 200+ users with cost sensitivity — Direct Routing. The deployment cost amortises.
• Mobile-heavy workforce — Teams Phone Mobile via Telstra. Replaces the corporate mobile fleet with the Teams Phone identity unified.

The hidden cost — common area phones, attendant consoles, paging

The user licence is only part of the cost. Add: Teams Common Area Phone licence (~$11 AUD/user/month) for reception/lobby/meeting-room phones, Teams Phone Resource Account licence (free) for call queues and auto-attendants, and the physical Teams-certified device (Yealink, Poly, AudioCodes phones $200–800 each). For a typical AU mid-market deployment, hardware is approximately 50% of the year-one cost.

What we recommend for AU mid-market in 2026

For most Australian mid-market organisations Frontrow advises Operator Connect via the incumbent carrier as the default starting point — strong cost position, no SBC complexity, retains the carrier relationship. Direct Routing is right for cost-sensitive 200+ user deployments where there's in-house or partner SBC expertise. Microsoft Calling Plans for small organisations or where decision speed matters more than per-user economics.
