Hello Bill & 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) What phone service provider (phone company) you have for this phone line?
2) If you have ANY other devices (phones, fax, alarm system, etc.) attached to this same phone line (not part of the MAIN system), and if so, are they working properly?
3) WHEN did this issue first begin (or was noticed)?
May I also ask if you can double-check the Model - printed on the bottom or back of the MAIN BASE UNIT?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
