[asterisk-users] Voicemail volume patch

[kjcsb]

There is a patch available for the quiet voicemail volume issue (bug 6237)
but it isn't intended to work with 1.2.9. The patch below will give you this
functionality for 1.2.9. Add the volgain= parameter to voicemail.conf and
make sure sox is installed.
