Ask a Phone Systems Question, Get an Answer ASAP!
Hello Herb & Welcome to Just Answer,
Sorry to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) The Model Number of the phone system you are working with? That model should be printed on a sticker on the bottom or back of the main base unit and START with KX-TG.
2) Has this system EVER had those lights come on when a message has been left?
