Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your phones.
May I ask:
1) The AGE of this system?
2) The TOTAL number of cordless handsets you have with this system?
3) WHEN this issue began (or was first noticed)?
4) Do the "indicator lights" on the handsets still "flash" - when an outside calls comes in (assuming you are watching)?
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)
