It doesn’t surprise me that the French escort so many airliners, their controllers are the worst in Europe at letting you fly out of radio range. Don’t they have a system for handing you over before this happens? This has happened to me twice in as many months, I just ASR them now.
Before someone in ATC has a go, no I don’t know it is happening because you hear almost as much R/T on the frequency except that it gradually becomes just other aircraft as the ground station goes out of range.

PS Yes we were monitoring 121.5 on both occaisions. Had to reestablish comms via another a/c, they hadn't even noticed we were out of range.
