How to configure the Busy-on-Busy feature in Teams to the user can control the call answering rules in Teams client

Teams Busy-on-busy option in Teams calling policy allows users/admin to configure either want to ring to the secondary call when the user is already on the existing call, conference, or call on hold, but the user cannot manage these options themselves. 

Now Microsoft released a new option in Busy-on busy settings to "User-controlled", which allows users to configure the busy option how they want to handle the calls.

•  Login to Microsoft Teams Admin Center and Navigate to the Voice folder
• Select "Calling Policies" and select the existing policy or create a new,
• Scroll down to the "Busy on busy when in a call" option.

Admin Options: -

• Not Enabled - this busy option let new incoming calls still be routed to the user while the user is already in a call /conference.
• Enabled - The new incoming call will be rejected with a busy signal.
• Unanswered - This busy option will use user unanswered call settings defined on the Teams client either to route the incoming call to voicemail, or forward the call to call delegates, Call Group, or external PSTN number.
• User controlled (new option) - This busy option lets the user configure the settings how they want to handle the busy option.

When calling policy set to "User Controlled" -

Navigate to the "Settings" option in Teams client and click the "Calls" tab, you will see a new option "when you're in a call. and receive another call" option" with the below options,

• Let new calls ring me - This is the default option, this option allows the new call to ring even when you are on call/conference/hold.
• Play a busy signal - When will fail with a busy tone.
• Redirect as if call is unanswered - This option will use your existing unanswered call answering rules.

In this example, we are using the "Redict as if call is unanswered" option and see the different options to route the calls.

By default, the call answering rule sends the unanswered calls to "Voicemail". However, you can configure different options based on your requirement and setup,

1. New Number or Contact - This option allows you to configure the call forwarding to either a PSTN number or Internal Contact.

2- Do nothing - This simply disconnects the call.

3. Call Group /Hunt Group - You can configure the inbound call to ring a group of users all at once or in the order of the contacts in the list.
