[asterisk-users] how to force Asterisk 1.4 to use soxmix

[Jorge Nunes]

You can use the variable MONITOR_EXEC in your extensions.conf to specify
the shell command to be invoked by the Monitor application to mix the
voice files.

The shell command will be invoked with three command lines arguments
appended: the file recording for the in leg (created by Asterisk); the
file recording with the out leg (created by Asterisk); the path of the
file where the mix result is supposed to be dumped to (i.e. the soxmix
(or equivalent) outfile).

Some examples in http://www.voip-info.org/wiki/view/Monitor+stereo-example
