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:
a
Append to the file, instead of overwriting it.
b
Only save audio when the channel is bridged.

This does not include conferences or sounds played to each bridged
party.

v(x)
Adjust the heard volume by a factor of x (range -4 to 4).
V(x)
Adjust the spoken volume by a factor of x (range -4 to 4).
W(x)
Adjust both the heard and the spoken volumes by a factor of x (range -4 to 4).
