[Freeswitch-users] session.recordFile create empy wav in while loop

[Steven Ayre]

I'd need to set up a testcase to confirm it, but I think it's probably
that recordFile blocks and doesn't return until it's finished
recording at the end of the call. As a result on the next loop
iteration there'll be no call so nothing to record.
