Does anyone know where I can get ATC callsigns for my add-on aircraft. For example: my A340 Pro came with ATC callsigns for Air Canada, Air France, and Iberia but none of the other airlines (Virgin Atlantic, Singapore, Lufthansa, etc.). I have already tried searching www.avsim.com
without any luck. I have heard of something called "editvoicepack", but I don't know if this is what I am looking for.
Your help is greatly appreciated,
BTW: It's for FS2004
