Thank you all for the great advice. Although fairly new to Asterisk, and relearning systems administration, it has helped put some perspective on the matter for me.

In my experience, most people (users) use their voicemail similar to email, they keep everything. Especially love struck college kids. I think Asterisk has a soft limit of 1,000 (maybe it is 999) messages as the max per inbox that can be changed in source. I suppose if you limit the max time allowed and the max inbox limit it might help but I think your 60GB estimate would be quite low in the real world. BUT, that is based on when I was in college and I was one of the very few to have my own cell phone (dating myself a bit). So in the real world, I am not sure how much use the system would actually see.
