“Where do I plug the headset Panasonic KX-TCA430 on a Panasonic KX-TG4012N phone? I recently purchased a Panasonic KX-TG4012N. The Bestbuy website indicated that the Panasoninc headset kx-tca430 is one of the accesories for this phone, however when i got the phone there were no place to plug the headset. I got an answering saying that the phone is compatible, if it is where can i plug the headset?”
