Hello Doug & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your machine.
To help you with this issue, may I ask:
1) The Make & Model Number of the answering system you are working with?
2) What is the AGE of this system?
3) WHEN did this issue first begin?
4) What service provider (phone company) do you have for this phone line (where the machine is attached)?
