- If the problem is just on one of your phones, do this
- Check to make sure the phone is switched to touch-tone (tt). You’ll find the switch on the side or bottom of your phone set.
- Press each button on the phone's number keypad to make sure they’re not sticking or making a dull sound instead of a clean tone.
