Hello & 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) Can you double-check the MODEL of the phone system you are working with? That should be printed on the bottom or back of the main base unit of the system.2) How long have you had this system?3) When was this issue first noticed?4) Is the correct TIME showing on the handset display?
I didn't see a response back for my first questions, but I believe I may have found the instructions for this (for a DECT 3135 system.
See attached image below (you may have to click on the image FILE NAME to view it.
Please take a look and let me know if that works for you - to turn OFF the Do Not Disturb feature.
