Hi Daniel,
I'm intrigued by this and wanted to try it out - but I'm wondering how
you get Asterisk to call sox at all during Voicemail()? Our server
doesn't even have sox installed, so I'm not sure how to go about
tricking Asterisk into running a different one.
To do anything useful you would have to get sox installed on your
server. But to get asterisk to run a different/fake sox, just install
whatever you want to run as /usr/local/bin/sox and then edit your
safe_asterisk script as I mentioned below. Asterisk runs the program
'sox' using the first match in your $PATH, so by updating the $PATH
before asterisk runs you can direct it to run a different sox
program. Be aware that this could pose a security issue as some
systems allow regular users to modify /usr/local/bin. So people could
install other programs that asterisk runs into that directory as well
to get elevated privileges. For me it is not a concern as the machine
is used only for Asterisk and only accessed by our IT department.

Thanks.
I had a similar problem in our setup where we e-mail the recorded
messages to e-mail retrieval. But this also helps standard phone
retrieval too. What I did was edit the /usr/sbin/safe_asterisk
script
and add:
PATH="/usr/local/bin:$PATH"
At the top of the script. This would let me override the default sox
implementation that Asterisk uses. Then I loaded in a script (called
sox) that would compress and normalize the recorded audio (It
compresses to deal with the spikes of the noise of the handset being
hung up, etc.). It works pretty well for us and makes the volume
pretty good so we don't have to crank up the volume on our computers
or phones to listen to voicemail messages. And we can't adjust the
rxgain as it is already a good volume for normal calls.
