I think he is talking about the screen where you can enter in an extension number or trunk to "monitor" and the screen will show you when a call comes to the phone, when it goes off hook, when it goes back on hook, if it puts the call on hold, or in the case of an outgoing call you can see the digits being dialed... It's more like an activity trace. I know you can do that in the 4K - I used to use it a lot on 9006. I think you do want to use RTDS for that, but not TSKA - which is basically a remote control for phones. Typically with TSKA as soon as a local user touches the phone it will bump off your session, so you really can't use that to watch one. You can also use RTDS can also do stuff like watch the D-Channel on an ISDN trunk and other fun things like that.
It would be important to note that if RTDS is not enabled on your system and you go into software activation to enable it, DO NOT just arbitrarily enable everything in there. The more of those things you have activated and never use the more sluggish your system can become from a maintenance standpoint.
