MS Teams Direct Routing - Licensing Guide

MSThis guide provides an overview of Teams licensing for Direct Routing and it's features. 

To watch a quick video on Teams Licensing for Direct Routing, click below.

General Licensing:

The following licenses work in conjunction with an E1,E3, Microsoft 365 Business Basic, Microsoft 365 Business Standard, or Microsoft 365 Business Premium License.

This will allow you to have basic Teams set up with the following features.

·         Chat

·         Channels

·         Teams

·         Teams to Teams Calling

·         Teams Meetings

·         Voicemail


Users who wish to utilize voice calling and have a voicemail box will require one of the licenses above as well as either a Microsoft 365 Phone System license or a Microsoft 365 Business Voice (Without Calling Plan) license.

This will allow PSTN (or 10 Digit external) calling via Teams

The Microsoft 365 Phone System Business Voice without Calling Plan is only suggested if you want all your users to have both Microsoft 365 Phone System and Audio Conferencing in one license.

If only a select few phone users need Audio Conferencing, then we suggest using the Microsoft 365 Phone System license and adding the Audio Conferencing license to only those who need it.


Audio Conferencing refers to having a phone number that people can dial into to join a Teams meeting. Everyone with a basic Teams set up will be able to host and join a conference bridge. But only those with the Audio Conferencing license will have a dial in number.

An E5 license has all the previously stated features within this one license including Basic Teams, PSTN Calling, and Audio Conferencing.

Special Purpose phones:

Lobby Phones or Conference Room phones in most cases will use a “Common Area Phone” license.

This is a unique license as it doesn’t require any additional licensing to function. However Common area phones DO NOT get the voicemail feature. If that is a requirement, then it would be suggested to license them like a normal Teams user.

It is also recommended to set Conference Rooms up as Resource Accounts, so they can Auto Accept Invitations from users wishing to book the conference room.


The Teams Meeting Room license is used when there is an Advanced Audio/Video capable Room System. It acts as an all in one for these types of rooms. It is recommended to use a resource account and this licensing in conjunction with a Resource mailbox in exchange.

It contains the following features:

·         Audio Conferencing (Including the dial-in number)

·         Intune

·         Phone system license (A DID can be assigned to it)

·         Voicemail box


Special Purpose Licensing:

The “Microsoft 365 Phone System – Virtual User” licenses are a no cost add on. They are used to Add Phone numbers to Auto Attendants and Call Queues.

Only the initial Auto Attendant or Call Queue requires this license as it will have a number assigned to it. Connecting Sub Menu’s and Groups do not require this license as they are branches of the same routing tree.

Please contact your Calltower Representative for more information about Teams Licensing.
