Summary: MixMonitor is not releasing the file handle on the
recorded file
Description:
I have been using MixMonitor in my dialplan through all the 1.6.0.x line
and recently updated to 1.6.1.0. Upon update it quit working.
My scenario is as follows:
I accept an incoming call, prompt for some IVR, start MixMonitor with b
option. Subsequently I initiate a Dial command to an external endpoint.
On answer the conversation starts recording to a temp directory on my
server. After either end hangs up, the dialplan continues to the h
extension where I launch an AGI script to convert the wav sound clip to mp3
and do some other post processing.
In all builds prior to 1.6.1 this all worked great. However starting with
1.6.1 when I externally launch the sox command via the agi script the
resultant file has no audio. I did some testing and discovered that this
behavior is the same as if I am mid-call even though the line is hung up.

StopMixMonitor race condition (not giving up file immediately)
StopMixMonitor only indicates to the MixMonitor thread to stop
writing to the file. It does not guarantee that the recording's
file handle is available to the dialplan immediately after execution.
This results in a race condition. To resolve this, the filestream
pointer is placed in a datastore on the channel. When StopMixMonitor
is called, the datastore is retrieved from the channel and the
filestream is closed immediately before returning to the dialplan.
Documentation indicating the use of StopMixMonitor to free files
has been updated as well.
