If you are using RedHat or CentOS, installing sox should be as simple as:

 	sudo yum install sox

Other distros have similar commands.

I think this is a bad approach. It's going to be a big "gotcha" down the 
road for somebody :)

A quick grep through the Asterisk (1.2.28) sources shows res_monitor using 
soxmix if the channel variable MONITOR_EXEC is not defined -- but nothing 
in app_voicemail. Am I missing something?
