# Handle PSTN calls from the 8x8 for Microsoft Teams app

Users without a Teams Phone license who use both Microsoft Teams and the 8x8 Work app (desktop, mobile, or web) can place Public Switched Telephone Network (PSTN) calls using the **Calls** ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/image-FUQK2VIX.png?sv=2026-02-06&spr=https&st=2026-11-03T21%3A14%3A11Z&se=2026-11-03T22%3A14%3A11Z&sr=c&sp=r&sig=RKSeGBPibmdhF5qpWxYkuLPeiG5roV5s%2FZmBzmlUz8Q%3D) option in the 8x8 for Microsoft Teams app (8x8 Teams app) ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/image-A1C9YMW7.png?sv=2026-02-06&spr=https&st=2026-11-03T21%3A14%3A11Z&se=2026-11-03T22%3A14%3A11Z&sr=c&sp=r&sig=RKSeGBPibmdhF5qpWxYkuLPeiG5roV5s%2FZmBzmlUz8Q%3D) .

## How to place a PSTN call

When placing a PSTN call to external users from the integrated **8x8 Teams app**, the call is initiated from Microsoft Teams but handled through the 8x8 Work app mini call control that is always-on top when using the native desktop 8x8 Work app. The call experience includes two legs—an inbound call which you answer on the 8x8 Work app, followed by the outbound call to the destination party.

> [!WARNING]
> Important:
> 
> You must have the 8x8 Work app (desktop, mobile, or web) open to be able to place PSTN calls from the 8x8 Teams app within Microsoft Teams. When using the desktop 8x8 Work app, it can stay minimized or running in background so you can rely on the 8x8 Teams app and just benefit from the 8x8 Work for desktop incoming call popup and active call control mini windows that are available on top of all other windows.

**To call a PSTN number from the 8x8 Teams app**:

1. Log in to the 8x8 Work app (desktop, mobile, or web).

> [!TIP]
> Tip:
> 
> When using the 8x8 Work desktop app, close the window; it will run in the background.
2. Log in to Microsoft Teams.
3. From the menu, click **8x8** ![](https://cdn.us.document360.io/e3a59e39-abd3-4423-964c-0a4008dc5673/Images/Documentation/image-6CBDDT0D.png?sv=2026-02-06&spr=https&st=2026-11-03T21%3A14%3A11Z&se=2026-11-03T22%3A14%3A11Z&sr=c&sp=r&sig=RKSeGBPibmdhF5qpWxYkuLPeiG5roV5s%2FZmBzmlUz8Q%3D).
