Hello Susan & Welcome to Just Answer,
I'm Greg and will do my best to assist you today.
Sorry to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) How many "rings" is the system set to - before the answering system picks up the call?
2) What phone service provider (phone company) you have for this phone line?
3) If you have ANY other devices (phones, fax, etc.) attached to this same phone line and if so, are they working properly?
4) Do you have another phone (such as a cell phone or neighbor's phone) that YOU can use to place a TEST CALL to your Panasonic number?
