I have noticed that making system recordings over FreePBX seems to have a problem. I am not sure if this is a known bug.
When a recording is made if you have any dead space in your recording after it has been recorded it strips this away. So when you pause or want to leave a small gap in a recording it gets removed from the recording by FreePBX.
It also seems to cut my speech off at the very end. Anyone else seem to have this issue?
