How can I send dtmf tones in calls?

So far all I could do is a btn to play wav files like DTMF, I listen to it but when I’m on a call it doesn’t send, I can’t take control of the mic. Any ideas ?, thanks

this might be a task for an Extension Developer to create a new extension, see also
https://developer.android.com/reference/android/media/ToneGenerator.html

alternatively you could write your own extension…
more information about how to create an extension see the App Inventor Extensions document
however that will be more advanced and will require some Java skills…
