This is a well featured telephone. I am not sure when it was made but it has a switch for either pulse dialling or touch tone. I would guess at around 15 years old but not sure. Specifications on the box are.
Pulse/Tone selector, Hearing Aid Compatible, Tone Button, Call ringing /In use light, Recall, Redial, Mute, Ringer Control.
This must be a rare find and may be useful for being able to switch between pulse dialling and tone dialling when testing lines etc.
The box is not perfect as you can see but the telephone is. I have plugged each one in and are working correctly.
Only four available and this listing is for one only.
