EditVoicepack allows easily adding missing callsigns, aircrafts, and airports to FS2004 ATC. "Out of the box" it provides 800 new callsigns and corrects several mistakes. The centralized upload system ensures new callsigns are easily avialble to all users. Requires the Microsoft .Net Framework 1.1. This version does not support FS 2002. By Lars Moellebjerg.
