Does any one know how to implement "FEATURE 4" on an NEC UT880? As an example, say I want to look up the port number for a specific UT880 from that phone?

note: the phone does respond to FEATURE 4 but I don't see how to go on from there

(I'm referring to the feature as implemented on DT700 phones - like hitting the small round center button in the middle of the left/right/up/down buttons followed by 100,200,300,etc or also by either hitting the up down buttons (feature 6 works but you don't increment that one on either model IP phone)

Simply would like to go to a specific UT880 phone and get the same information "center" round key plus 100, 200,300,400, etc. gives at a DT700 phone from a UT880
