[Freeswitch-users] BUG??? Bad mixed Audio record_session

[William King]

Are you able to reproduce this on demand?
If so how long do you have to record a sound file for it to occur?
Is it always the beginning of the sound file that gets copied to the
end, or is it X minutes prior to the end of the file?
