MixMonitor() — Records a channel in the background, mixing both directions synchronously
Records the audio on the current channel to the specified
file. If the filename is an absolute path, MixMonitor() uses that path; otherwise it
creates the file in the configured monitoring directory from asterisk.conf.
If command is specified, it will be run
when recording ends, either by hangup or by calling StopMixMonitor().
The options parameter can contain zero
or more of the following options:
Append to the file, instead of overwriting it.
Only save audio when the channel is bridged.
This does not include conferences or sounds played to each bridged party.
