Cheaters?

I don't know what that one guy was talking aobut but this topic is about getting voice to work over System Link because Rainbow Six: Lockdown and Rainbow Six: Critical Hour DO NOT have the option to use headsets to talk over system link. Even though Rainbow Six 3 and Rainbow Six 3: Black Arrow DO let you use headsets over system link. This was a horrible mistake/decision on UbiSoft's part, whatever the reason may be.
Anyways... I was looking at the files and directories of Rainbow Six 3 and Rainbow Six: Lockdown side by side and they are TOTALLY different. Rainbow Six 3 has not even 2,000 files while Rainbow Six: Lockdown has over 20,000 files! I have no clue where the vioce option would be in Rainow Six 3 so I don't even know where to start on Rainbow Six: Lockdown.
I dunno if this is even possible... I guess I just have to give up and accept defeat on this mission
