Hello & Welcome,
Sorry to hear of any issue you may be having with your phone(s).
May I ask:
1) The TOTAL number of cordless handsets you have with this system? If more than one, do ALL handsets not work?
2) Do you have ANY other devices (phones, fax, etc.) attached to this same phone line and if so, are they working properly?
3) When you say you "hear the rings" when you call from your cell phone, are these rings heard IN the cell phone ONLY?
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)
