Hello, from the Call Health option on the MS Teams client, I see the receive codec is SATIN, however the send codec is unknown. Does anyone know what the audio codec would be unknown? The call is on the same network peer to peer teams clients. Attached screenshot

I tested at my end and got the same results as yours:
Then I tried searching around, but hardly find any explicit explanation about this metric except the "Informational only" mentioned in this article. However, during my tests, seems like the call quality wasn't affected by the "unknown" sent codec. Is it the same as yours? If yes, in other words, there's no issue with the call quality, personally I assume we can just ignore this.

Good to know that your voice quality is ok as well. So for now, we can temporarily leave it as it is. Anyway, should you meet any other issues when using Teams client, you can still feel free to post a thread for discussion using the “office-teams-windows-itpro" tag.
