IVR configuration in Microsoft teams - Configure Busy call message

Hi All,

Please share your thoughts.

I am currently working on Microsoft Teams IVR configuration for one of our customers.

In my setup, I have a main Auto Attendant that transfers calls to either an English-speaking or Arabic-speaking Auto Attendant. Based on the menu selections, calls are then routed to an operator. Additionally, both Auto Attendants are configured with a "Dial by Extension" feature, allowing users to reach specific extensions directly.

My question is regarding the busy message configuration. I have noticed that the Auto Attendant transfers a second call to a user's extension even when the user is already on an active call. Is there a configuration available to play a busy message, such as "The user is currently on another call. Please try again later"?

    I ran into this too when setting up our https://activecalls.com. What worked for me was using the Call Queue overflow and timeout settings together with custom announcements. I recorded a short “we’re currently busy” message and set it to play when the call hits max wait time. It’s not a perfect busy signal, but it gives callers a clear update during high traffic.

    Hi,

    I would recommend you to look into the Calling policy and configure the Busy on Busy configuration that would help to route the second call based on the users configuration to send the call to voicemail after 20-30seconds accordingly.
