Hello & 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 TOTAL cordless handsets do you have with this system, and if more than one, do ALL handsets have this issue?
2) Is there anything DIFFERENT on the display of the failing handset - from on that is working?
3) Does this handset "ring" - when a call comes in?
Please REPLY using the box below and the SEND button.
If you see ANY requests for "additional services" - such as a phone call - please understand that these are sent BY THE SITE (and not me).
Feel free to DECLINE any such offers, and continue in this text/chat form.
