Recently I noticed that ATC drops the callsign sometime and identifies by flt. number only.
It is not a case of a missing callsign as it IS pronounced sometimes (e.g ATC says number only and AI answers with both callsign and number, or vice-versa).
My question is, whether EVP has any control over this? can I set somehow that both callsign and number will always be pronounced?
The most likely cause of this is AIG AI Manager.
Unfortunately the developer of AIG AI Manager decided to use EditVoicepack to design an addon… that isn’t compatible with EditVoicepack.
Somewhere in the settings if AI Manager you should be able to deselect the voicepack it downloads. You can’t just delete the file as it will reinstall it. I do not know exactly where the setting is, so if you can’t find it I recommend posting in the AI Manage forum.
