With my recent finding, i can teach you how to hear your realistic callsign in IF Live…
For first, choose a callsign.
Mine will be EZS1234
So when you choose that one, go then to settings, general and choose pronouncations in Accessibility settings.
Be sure that the only language is English US.
Row 1: EZS1234
Line 2: Top Swiss One Two Three Four (or Twelve thirdty four) something like that
Hope this help
