Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist you today.
Sorry I didn't see your question earlier and to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) What happens when you TRY to set up the answering system, and a call comes in?
2) Do you have access to an outside phone - such as a cell phone - so you can place TEST CALLS to the number where the Panasonic system is connected?
3) What phone service provider (phone company) you have for this phone line?
