[asterisk-users] Voicemail- Recorded Mesage Low Volume

[CunningPike]

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.
