Well, for example, I can't see the "answer table" when reviewing caller id information without feature package 3..Also, (feature#6) which clears the call forward information from the display doesn't work without feature package 3.

It would very nice if there were a PBX out there I could use with the DHS phones. I have a ton of them. Not to mention the other equipment I have such as voicemail, calleder id etc etc.
Im just not in the market for a new phone system right now :-(
