One phone jack was configured for a 2-wire answering machine with a cordless phone along with the Panasonic phone. It used to work perfectly but about a month ago the answering machine quit recording and I can no longer make calls on the cordless phone. When you press 'talk' on the cordless phone, you get what sounds like a busy signal. I can receive calls on the cordless phone though. If you unplug the Panasonic phone the cordless phone and answering machine work fine. It will just no longer work with both phones on the same jack. I suspect the 'program' switch got put in the 'program' mode for that phone and caused something to get messed up.

Does anyone know what needs to be reprogrammed on the local Panasonic phone to allow both the phone and answering machine to work on the same jack?

Thanks,
