[asterisk-users] hardware requirements..

[R.R. Libera]

Hello,

I have Asterisk running on Debian Sarge. I use AGI to billing and now 
I´m planing to separate mysql from Asterisk Box, resulting:

(Asterisk + AGI) ----- (Iptables + showrewall + Apache + PHP + MySQL)

What hardware configuration do you recommend for the second box, in 
order to maintain the quality in calls?  I´m planning to run upon 30 
(E1) concurrent calls.

Thanks in advance.
