Yes, my system is the DK14. I have a 20 button display phone and the phone that I want to ring on incoming calls is the 10 button phone. I have 3 books on the system and not a single one has anything about programming. If I could get into the program mode I'm sure I could muddle my way through it (or screw it up further), but I can't even get to program mode. The company we bought these phones from won't give me a spec of information. They want to send a technician out to program the phone to ring. $70 minimum charge to make one lousy phone ring. I'm not stupid but there's no "program" button on my phone & no book to guide me. Any help would be greatly appreciated.
