on any CM phone that has a display, there is a feature called "Self Station Display?", it must be enabled on "change sys feat":
display system-parameters features Page 1 of 18

Self Station Display Enabled? y
then you administer a "feature" code for it, via "change features", feature name is: "Self Station Display Activation:"
If the phone is logged in, the port and extension # will show up, if its isn't jus the port # will show up (for digital phones)
