Microsoft Teams Auto Attendant/Call Queue - We can't upload the audio file. Verify the contents of the file and try again.

Many companies are migrating to Teams Voice, transitioning from legacy PBXs such as Cisco, Avaya, and Coral. In the past, for Hunt and IVR voice prompts, they would reach out to professionals or companies that specialize in these prompts, or they would record them internally as a low-cost option.

Option #1: You can convert speech to text and use it for Teams CQ/AA greetings and menus.

Option #2: You can use existing WAV or MP3 files and upload them as they are.

I decided to write this article based on my own experiences with various failures, such as the following:


Error: Microsoft Teams Auto Attendant/Call Queue - We can't upload the audio file. Verify the contents of the file and try again.



Solution: Change the sampling rate to something Teams CQ&AA supported.

How it is been done: I had heard about this tool before, but I was recently convinced by my colleague Lawrence, and it's a free tool. I’ve seen similar articles, but I’ve never come across one that offers a proper resolution


Open the existing WAV or MP3 file; it doesn't matter what sample rate it was recorded at as long as you can listen to it. If you don’t need to cut or change anything, the next step is to EXPORT. 

What I did was export to a low sample rate of 8000 Hz, without making any other changes in the following window.



Export to file location,


Upload this file afterward to Teams CQ/AA; it should work without any problems. This method was also used recently with WebEx Contact Center.
