How do I locate the caller ID section to turn it on so that the incoming telephone number shows on the tv screen

Here is the information for the newer cox contour cable box:

Cox Phone tv settings.

Cox phone caller id settings for tv, 2023.

You need to do this from your tv contour remote.

Menu > "Preferences"> cox voice > (Set to "on" or "off" ).

"Voice" control is for the tv caller id settings.
