SOURCE: Uniden Cordless Telephone with Dual Handsets and Caller ID DXI-55

check if you have a manual. from there search up in the manual caller id settings. you have turned off the caller id option.

SOURCE: Need English documentation for Uniden Sireus 5080 phone & 0500 handsets

Here is the solution I found.
I also bought this equipment and also didn't find anything suitable in the internet, BUT a phonecall to the suplier EUROCOM brought the solution.
I called their service nr. 03-9029000 and got the English user manual as a PDF doc. by email.

I had the same problem until today. This is what I did:
I opened up the handset and took most of it apart:
There are 2 screws in the battery compartment and you have to push something in on the sides to pull it apart. It won't come completely apart because there are wires connecting to the speaker. There are 5 screws on the inside that hold the board to the phone. I unscrewed those. The buttons are all on 1 rubber sheet. The problem is that the 4 metal connectors under the 4 way button (not on the board, the ones on the back of the rubber) have somehow deteriorated. To fix it I glued a very small piece of tin foil (I used a really thin brand) to each of the 4 connectors. They have to be done separately and the foil can't be too thick or the foil will be touching the board without a button press (found this out the hard way). Test it before tightening the screws to make sure everything worked and then put it back together.
Note: You may need to ground yourself so static electricity doesn't fry the board. If it breaks the phone, don't blame me :) I went this route because it was either play around to find a solution or buy a new phone. I don't know how long this will work for, but I hit all the buttons a bunch of times and they all work.

Unplug the power supply to the base of the main handset, wait 10 seconds and plug back in.

After cracked open the handset, I am pretty sure most of problem is not circuit issue. It's the sticky pad somehow aged. I put a small piece of aluminum foil between the rubber key pad and inner plastic conductive pad, and fixed it. No glue needed so far.
