# 8x8 Voice for Teams: Handling Additional Inbound Calls using Busy on Busy

## Overview

This article addresses the specific scenario in which PSTN calls are received by 8x8 Voice for Teams users when they are already on a call, and provides a solution to prevent unwanted interruptions from other inbound calls.

> [!WARNING]
> Important:
> 
> - **Admins, Only:** The instructions outlined here must be performed by a Microsoft administrator in the **Microsoft Teams Admin Center**.
> - It’s recommended that you first test your new settings on selected individual Voice for Teams users before implementing en masse.

## Applies To

- 8x8 Voice for Microsoft Teams
- Inbound PSTN Call Handling
- Busy on Busy

---

## Procedure

The instructions below are borrowed directly from Microsoft’s [**Routing inbound calls**](https://learn.microsoft.com/en-us/microsoftteams/inbound-call-routing) article, which you can read for more information on this topic.

### Configure Busy on Busy

**Busy on busy** during calls (also called "busy options") lets you configure how incoming calls are handled when a user is already in a call or conference, or has a call placed on hold.

New or incoming calls can be rejected with a busy signal or can be routed accordingly to the user's unanswered settings. Regardless of how their busy options are configured, users in a call or conference or those with a call on hold are not prevented from initiating new calls or conferences.

> [!NOTE]
> Note:
> 
> This setting is set to Off by default. It also does not apply to incoming group calls or meeting join requests.

1. In the left navigation of the **Microsoft Teams admin center**, select **Voice** > **Calling** policies.
2. Select the policy you would like to update, or select **Add** to create a new policy.
3. Choose a **Busy on busy** option to determine the action taken on additional calls:
  - **Off:** No busy option is enabled and new or incoming calls can still go to the user while the user is already in a call.
  - **On:** New or incoming calls will be rejected with a busy signal.
  - **Use unanswered settings:** The user's unanswered settings in Microsoft Teams will be used, such as routing to voicemail or forwarding to another user.
  - **Let users decide:** Users can determine their busy options choice from call settings in the Teams app.
4. Select **Save**.
5. Affected Voice for Teams users should log out of and back into Teams to enable this change.
