Yes, I made a new flight today with a fresh VoiceSetExclusions.dat but I have always the same issue.
An other one I noticed with CP mode=0 (Off). When I contact for the first time a new Departure or a new Center (Key "0"), if I wait +-3'' the Departure/Center contacts me before I press the Key "0". This seems occurs only with Departure/Center/Approach.
Last but not least

please, do you think you can make something about the "Did you copy" and the real time Altitude monitoring described in my previous post there :

Just in case, joined my last Log files.
Thank you in advance,
