Microsoft Teams Lobby Auto Admit

Overview

A safe and secure way to admit VTC rooms into Teams meetings.

   • Azure Communication Services

Microsoft Teams Policy

In order to apply/grant the policy access you need to add the App Registration to Global policy. To do this, you will need to have the Application (Client) ID or provide it to your Microsoft Teams Admin.

You can find Microsoft guide on installing the Microsoft Teams Module here.

To be able to set/add policies you will need to be able to run commands using MicrosoftTeams module in PowerShell.

1. Import Microsoft Teams Module to be available in PowerShell by running the following command
   Import-Module MicrosoftTeams
2. Connect to Microsoft Teams backend using:
   Connect-MicrosoftTeams
3. You can double check if there are any pre-existing policy/apps assigned to Global or any other existing Policies by running:
   Get-CsApplicationAccessPolicy
4. To add the new app registration for Microsoft Teams Lobby Auto Admit to function there are two options:
   

   1. If you have any application ID's listed in Global you will need to use an alternative method, as performing Grant-CsApplicationAccessPolicy will replace everything in Global with application ID's from the Policy you have applied to it. 

      1. Instead of creating you can add additional app registration to a policy by running the following:

         Set-CsApplicationAccessPolicy -Identity <your_access_policy> -AppIds @{Add="<applicationid>"}
         

         You can use this to add the new application ID directly to Global if you do not have any other application access policies but have previously granted applications directly to global.

      2. Adding the new application ID to an application access policy you will need to grant the application access policy to global by running the following:
         Grant-CsApplicationAccessPolicy -PolicyName <your_access_policy> -Global

   2. The following is only to be used when there is no other Application policies in place and need to create a new one.
      1. To create a new policy run the following command.
         New-CsApplicationAccessPolicy -Identity ssky_lobby -AppIds <applicationid>
         
      2. Then you need to grant the new policy at global level by running the following:
         Grant-CsApplicationAccessPolicy -PolicyName ssky_lobby -Global
         

      3. You can move to configuring SUITE to configure the new app registrations.
