I've run into this a few times over the years but ran into it again on a flight today. Flying at cruise, no issues, get a handoff from ATC to a new center frequency. Change to that frequency, in the standby window it shows it as a center frequency. Toggle it to active, and its the same frequency but is now Airport X (in this case Munich Center became ETIH Info) At that point, ATC wont acknowledge me when I report in.
Wondering what I should do in this situation, how to get around it, etc...
Flight was LFSB - EPKK. Hand off was from Vienna Center (124.4) to Munich (120.65). Munich is showing as ETIH Info.
