I recently had a service call at the end of which I was asked to complete a survey. I was unable to do the survey, as -- while the dialpad was visible and pressing buttons entered them into the number field -- no dial tones were sent over the connection. This is the second time this has happened; I've never had this work. I am able to navigate DTMF menus if they're the first thing that I encounter, but it stops working at some point.
I'm not sure how many of these steps are necessary to replicate this, but I believe part of the issue is if the screen locks during a call. Somehow, the lock screen interferes or stops the Phone app from sending DTMF signals.
- Start a call
- Allow enough time for the screen to lock
- While the call is ongoing, try to return to the phone app and send DTMF signals
At step 3, you can press buttons but no tones will be generated.
