Thanks for the reply Ralf,
When losing contact i did try manually pressing the appropriate button, but no response. I do get the chime indicating that the transmission was made. I just repeated the flight from LFPG to EGBB without voice recognition, and all went fine. Difficult call, is it a MCE problem or a PFE3 voice recognition problem?

Do you also get the chime when using MCE?
Does the loss of communication always happen at the same point with the same flightplan?
Does it occur with different flightplans?

Yes, always get the chime.
So far, it happened at the same point with two different flight plans, traveling from South To North and contacting London Control over the English Chanel.

Please also attach the .json file from your Flight/FPP folder if it happens again (or if you still have the one from your last flight with this issue).

Apart from that try the following. If you don't receive a reply after checking in with the new facility after a handoff (I guess that is your issue) manually change to the frequency of the following center facility, check in there and see if you get a reply.
