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.

Subject: Re: [asterisk-users] capacity
I use standard wav (most compatible with players) so about a meg a minute.
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.
Thanks,
Steve Totaro
