DTMF options not working on S23+ phone / T-Mobile carrier.

When dialing an auto attendant / IVR in Teams and prompted to hit option 1 or option 0, it never gets the input from my Android phone. It's very frustrating as I am trying to implement the IVR for a company. I will test using another phone on AT&T (iphone) to see if the same issue occurs but I have seen similar forum complaints about this problem. Is this something Samsung development team is aware of?

I'm guessing you are in the states, you may want to post this on the US forum as you may get better advice

Possibly that's something your carrier can fix
