[Enable the 8x8 PBX Service](/documentation/docs/configure-and-enable-your-services-in-the-admin-portal#enable-the-8x8-pbx-service) 2. [Enable the Teams Service](/documentation/docs/configure-and-enable-your-services-in-the-admin-portal#enable-the-teams-service) > [!WARNING] > Important: > > Complete the 8x8 PBX Service setup *before* enabling your Teams service. This ensures that user location has been established, which is critical to the generation of unique 8x8 session border controller (SBC) domains in the Microsoft 365 environment that occurs during the initial Voice for Teams setup sync. If your domains fail to be generated and activated, users will not see the Teams dialpad, and will not be able to make or receive calls. ## Enable the 8x8 PBX service To sync of users with Teams, enable your 8x8 PBX service to allow it to connect to the admin portal: 1. In [**8x8 Voice for Microsoft Teams admin portal**](https://admin.msteams.8x8.com/), on the **Services** > **PBX** tab, click **8x8** in the dropdown list. ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/Configuring%20and%20Enabling%20Your.png?sv=2026-02-06&spr=https&st=2026-11-03T21%3A53%3A46Z&se=2026-11-03T22%3A53%3A46Z&sr=c&sp=r&sig=%2BWmGJK%2B1s4P0xiKRKfV%2B%2FPu%2Bs5L43gCK%2BoiAb6pL30U%3D) 2. Select the appropriate **Country** and **State / Province** from the respective list, then click **Add PBX**. ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/Configuring%20and%20Enabling%20Your_1.png?sv=2026-02-06&spr=https&st=2026-11-03T21%3A53%3A46Z&se=2026-11-03T22%3A53%3A46Z&sr=c&sp=r&sig=%2BWmGJK%2B1s4P0xiKRKfV%2B%2FPu%2Bs5L43gCK%2BoiAb6pL30U%3D) 3. Under **Calling Policy**, choose which service (*8x8* or *Teams* will provide voicemail service to your *Teams* service: - Select the **Manage Teams Calling Policy** checkbox, and choose one of the following options to be used: > [!NOTE] > Notes: > > - You can change this setting whenever necessary. > - For more details, see [Teams Calling Policies](/documentation/docs/configure-your-service-to-use-either-teams-or-8x8-voicemail#teams-calling-policies). > - For detailed configuration instructions, see [Configure your Services to Use either Teams or 8x8 Voicemail](/documentation/docs/configure-your-service-to-use-either-teams-or-8x8-voicemail#configure-service-either-teams-8x8-voicemail). - **8x8 Voicemail** and **8x8 Music On Hold** (recommended): 1. In the **Teams Voicemail** list, click **Prohibit Voicemail & Call Forwarding**. 2. In the **Music Hold** list, click **PBX Hold Music**. - **Teams Voicemail** and **Teams Music On Hold**, or any combination of *Teams* and *8x8* services: 1. In the **Teams Voicemail** list, click **Allow Voicemail**. 2. In the **Music on Hold** list, click **Teams Hold Music.**. 4. In the **Propagate Refer** list, click **Teams True Transfer** for best call transfer performance. 5. Click **Save**. > [!NOTE] > Note: > > PBX Service configuration does not trigger a sync between 8x8 and Teams. The above configuration only makes 8x8 PBX synchronization possible. You'll be prompted for your 8x8 and Teams credentials at a later stage to sync the 8x8 and Teams service users together in the admin portal. ## Enable the Teams service When a sync is performed, the service automatically allocates endpoints based on the location of 8x8 users. The **Enable Sync** function allows the portal to automatically configure the service, and set phone numbers directly into your Microsoft 365 tenant. Choose one of the following methods to configure the admin portal's *Teams* service to sync users with: - [Sync all Teams users](/documentation/docs/configure-and-enable-your-services-in-the-admin-portal#sync-all-teams-users) - [Sync Teams from a specified Azure AD Group](/documentation/docs/configure-and-enable-your-services-in-the-admin-portal#sync-teams-users-from-a-specified-azure-ad-group) > [!WARNING] > Important: > > Part of the Voice for Teams setup sync process will automatically add unique 8x8 SBC (Session Border Controller) domains to your Microsoft 365 service, and will activate them for voice. This process requires that a licensed user has their sign-in address changed to each of these domains, long enough for Microsoft to activate that domain in the voice subsystem. The sync process will do this automatically, using the first of these three methods that apply: > > - Use a spare license to create a user, then delete the user when finished. > - Change the sign-in address of the user whose credentials were specified for the sync if it has an appropriate license, changing it back once finished. > - Change the sign-in address of an arbitrary user who has an appropriate license, changing it back once done. The sync will wait up to 20 minutes for Microsoft to activate the domains before giving up and restoring the sign-in address. In most cases this is more than enough time. Occasionally the Microsoft subsystem that activates domains for voice may stop working and it could be necessary to wait up to 24 hours before trying again. > [!NOTE] > Note: > > To facilitate the creation of all required global 8x8 SBC (Session Border Controller) domains, it’s recommended to enable the Voice for Teams integration in the 8x8 Admin Console for at least one user from each global region before the initial setup sync process, if possible. ### Sync all Teams users When the service is configured to sync all Teams users, the admin portal will poll the Microsoft Teams tenant for all available users (users who have been assigned a Teams license). > [!NOTE] > Note: > > - When this **Sync All Teams Users** configuration is applied, the **Sync Now** process will perform a test of every Teams user for appropriate assigned Microsoft Teams licensing. Only Teams users with correct licensing enabled in both Microsoft services and the 8x8 Admin Console will actually be synced (connected) in the 8x8 Voice for Teams admin portal. > - If you have a large number of Teams users (1000 or more), or you need to sync one or more specific Azure groups of Teams members, you should follow the process to [**Sync Teams users from a specified Azure AD Group**](/documentation/docs/configure-and-enable-your-services-in-the-admin-portal#sync-teams-users-from-a-specified-azure-ad-group), instead. The syncs using that process do not test for appropriate Teams user licenses. **To sync all Teams users, follow the steps:** 1. On the **Services** > **Teams** tab. 2. Select the **Enable Sync** checkbox to enable the sync function. 3. Click **Services**. ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/Configuring%20and%20Enabling%20Your_4.png?sv=2026-02-06&spr=https&st=2026-11-03T21%3A53%3A46Z&se=2026-11-03T22%3A53%3A46Z&sr=c&sp=r&sig=%2BWmGJK%2B1s4P0xiKRKfV%2B%2FPu%2Bs5L43gCK%2BoiAb6pL30U%3D) 4.

The*green arrows* represent error-free calls, and *red arrows* indicate calls with problems. Hover over these arrows. A dialog opens and displays the recent call log. ### Sync Teams users from a specified Azure AD Group If you want to sync a large number of members of an existing Azure AD Group with their corresponding users through the 8x8 Admin Console, you need to prepare the 8x8 Voice for Teams admin portal fist by using **Large Tenant Mode**. > [!WARNING] > Important: > > - In the Voice for Teams admin portal, the **Large Tenant Mode** feature quickly brings large numbers of Teams users into the portal when a sync is performed, and also eases the administration of Voice for Teams users. > - To achieve this, the intensive-testing process of Microsoft user license is bypassed. Normally, when **Large Tenant Mode** is not enabled, this testing process is performed by the admin portal. In this case, it's especially important to ensure that your Teams users have proper Microsoft licenses assigned to them *before* performing a sync with enabled. This process automatically syncs your Teams and 8x8 users, when completed. If you have not already done so, first follow the required [**Enable the PBX Service**](/documentation/docs/configure-and-enable-your-services-in-the-admin-portal#enable-the-8x8-pbx-service) procedure, and then follow the steps below to enable sync of Azure user group members. > [!NOTE] > Note: > > The name used in our example Azure user group is **8x8 Voice Users**, but you can choose any name you wish. ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/Configuring%20and%20Enabling%20Your.jpg?sv=2026-02-06&spr=https&st=2026-11-03T21%3A53%3A46Z&se=2026-11-03T22%3A53%3A46Z&sr=c&sp=r&sig=%2BWmGJK%2B1s4P0xiKRKfV%2B%2FPu%2Bs5L43gCK%2BoiAb6pL30U%3D) **To enable the sync of Azure user group members:** 1.
