num-grp is one of the ones in the service pack. If youve got the newest service pack then you have the newest num-grp patch (I think its .7). I had the "already in use" problem too. I generated the report and it worked fine. When I uploaded it it failed and went into that locked condition. I had to restart the system to clear it. When it came back I changed direction and went the csv route. I generated a report picking the first and last name option, exported it, saved it as an excel file which makes it a lot easier to see, modified it (all you really need is the last name, first name and dn), imported it back to the pbx and then uploaded it. In my case the need for this was to make it possible to call acd users and cdp entries. I have a norstar and bcm running off this particular CS1K. Hopefully your not in a hospital and you can bounce the switch. Let me know if I need to explain more or differently.
