Microsoft Teams Phone:
Which licence do you need for calling?
Teams Phone turns Microsoft Teams into a telephone system. External calling requires three pieces to work together: an eligible Teams base, the phone-system entitlement, and a connection to the public telephone network.
In short
Phone-system entitlement, phone number, and telephone service are different things.
A Teams Phone licence enables the phone-system capability. Calling external telephone numbers also requires an appropriate calling provider or Microsoft Calling Plan.
- 01Teams Phone is the phone-system capability, not automatically the calling contract.
- 02Microsoft 365 E5 already includes Teams Phone, so an additional Standard licence would normally duplicate existing rights.
- 03E3, Business, and eligible Frontline plans generally require an appropriate Teams Phone add-on.
- 04Microsoft Calling Plans, Operator Connect, and Direct Routing connect Teams to the public telephone network.
- 05Call queues and auto attendants use dedicated no-cost resource-account licences.
Simply explained
How does calling through Microsoft Teams work?
Think of a traditional telephone system: a person needs system access, a phone number, and a connection to the outside world.
Microsoft Teams
The person needs an eligible Teams base licence. With plans sold without Teams, the required Teams entitlement must be provided separately.
Teams Phone
Teams Phone enables calling capabilities such as call transfers, holding, routing rules, and phone-number management.
Public telephone network
External calling requires a Microsoft Calling Plan, Operator Connect, or Direct Routing through a suitable provider.
Individual or shared
A user can have an individual number. Shared Calling allows several eligible users to share a central number.
Licence comparison
Which Teams Phone licence fits each scenario?
The correct licence depends on whether you are enabling a person, a shared phone, or a voice application such as a call queue.
| Scenario | Suitable licence | Practical consideration |
|---|---|---|
| Employee with Microsoft 365 E5 | Teams Phone already included in E5 | Still verify Teams access and telephone-network connectivity; avoid purchasing another Teams Phone Standard licence when the entitlement already exists. |
| Employee with E3 or a Business plan | Suitable Teams Phone Standard add-on | Check that the exact base licence qualifies. Phone numbers and telephone service may require separate arrangements. |
| Frontline worker | Teams Phone Standard for Frontline Workers or suitable add-on | Verify the eligible F1, F3, or Office 365 F3 base and the actual role. |
| Phone system plus Microsoft calling service | Teams Phone with Calling Plan | Combines the phone-system entitlement with a Microsoft Calling Plan; availability and included minutes differ by country. |
| Reception phone or shared phone | Teams Shared Space | Device-based licensing for a shared telephone; do not substitute an ordinary personal licence. |
| Call queue or auto attendant | Teams Phone Resource Account | Microsoft describes this specialised licence as no-cost, but it must still be obtained and assigned to the resource account. |
Which licence fits?
Calling Plan, Operator Connect, or Direct Routing?
The phone-system licence and telephone-network connection are separate decisions.
Microsoft Calling Plan
Depending on the country, Microsoft supplies phone numbers and calling packages. This can work well for straightforward requirements.
Operator Connect
A supported telephone provider connects its calling service to Teams. Assess the Microsoft entitlement and provider contract separately.
Direct Routing
A suitable provider or an organisation’s telephony infrastructure connects Teams to the telephone network. Include technical, operating, and provider costs.
Shared Calling
Multiple users can share a central phone number, but each participating person still needs their own Teams Phone entitlement.
Common mistakes
Which mistakes cause unnecessary spending or incorrect licensing?
Problems arise when users, phone numbers, devices, and technical accounts are treated as identical.
Adding Teams Phone to E5 unnecessarily
When the E5 subscription already includes the phone-system entitlement, another Teams Phone Standard licence is normally unnecessary.
Confusing the licence with a calling contract
Teams Phone alone does not automatically include external calling, telephone numbers, or calling minutes.
Giving expensive user licences to call queues
Auto attendants and call queues need their dedicated no-cost Resource Account licences rather than ordinary Teams Phone Standard licences.
Using one user entitlement for several employees
A shared telephone number does not replace individual Teams Phone rights for people using Shared Calling.
Fictional practical example
Fictional example: 40 employees and one central number
A fictional organisation wants 12 people to make external calls and needs one central call queue.
Count actual calling users
Only 12 of 40 employees need external calling, so purchasing Teams Phone for all 40 is not automatically justified.
Check existing entitlements
Where an employee already has Microsoft 365 E5, Teams Phone is generally included. Assess suitable add-ons only for the remaining users.
Assess connectivity and the queue separately
Select the calling provider or Calling Plan separately. Assign a no-cost Teams Phone Resource Account licence to the central queue.
Seven questions before deciding
Seven questions before deciding
- 01Which employees genuinely need to make or receive external calls?
- 02Is Teams Phone already included in existing E5 subscriptions?
- 03Do other users have an eligible Teams and Microsoft 365 base?
- 04Who provides phone numbers and network connectivity: Microsoft, Operator Connect, or Direct Routing?
- 05Does each person need a dedicated number, or is Shared Calling sufficient?
- 06Which call queues and auto attendants require no-cost Resource Account licences?
- 07Are shared phones better covered by Teams Shared Space?
Key takeaway
Teams Phone is the phone system. Telephone connectivity is a separate decision.
Start with existing entitlements, identify actual calling users, and then assess phone numbers, network providers, and technical resource accounts.
