Deploying Webex Call App in Microsoft Teams

In this post I am going to show you how to install the Webex Call app for your end users at a administrative level from the Microsoft Teams console.

So in April 2020, Cisco announced a new Call App for Microsoft Teams. The app launches calls through Webex technology, even when you click the call button in Microsoft Teams. 

To access this functionality, follow these steps:

  • Verify users have accounts activated in the Webex Control Hub
  • Ensure users are registered to the Cisco Webex Calling or Unified Communications Manager
  • Make sure users have the Webex app
  • Ensure you have Administrator privileges for Microsoft Teams
  • Update phone numbers for users in the Azure Active Directory

So lets get to it;


Go to Teams App –> Setup Policies

Best Practice / Recommendations

It is always best practice not to modify the Global (Org-wide default) policies. It recommended to create a new policy which will limit impact to the production environment.

Once you have either create a new policy or decided to modify the global policy. Click Add Apps

Search for Insights and click Add

While in the policy you may decide to add Insights as a Pinned App, you will need to add Insights app as shown below

Click Save

The Webex call application will now be installed and added to pinned apps with the Teams Client. As a global admin launch the application for the first time to approve the application in your Microsoft tenant.

As you can see below you now have the ability to make Webex call through Microsoft Teams.

Now for the Pros / Cons.


  1. Simple way to connect Webex calling functionality with Microsoft Teams
  2. Embedded buttons in Teams make the function easy to use


  1. Only works to connect two VoIP calling strategies. You can’t connect your chat messages or file sharing this way. 
  2. Calling opens a new window, which means there are more tabs for users to keep track of.
  3. Only works to add Webex Calling to Microsoft Teams. You can’t add Microsoft calling to Webex instead.
