I did not think that turning off the System volume would have such a crazy side effect of no DTMF tones. I could not find a way to see or affect the System Volume from within the phone app settings (via the 3 vertical dots). For me, the phone app setting of Play sound for keypad taps was already set to on, and as that is a more obscure setting, the System volume being off is probably the most likely cause of no DTMF tones, as it was for me. I had the same very frustrating and troublesome problem and it took me a while to find that I had to turn the System volume on to solve this issue.
