I am running a dual Opteron server at the moment which hosts both Asterisk, websites and Mail services under Xen. I would like to move Asterisk onto its own dedicated hardware as sometimes I do get jitter and voice breakup due to running virtualised.
I am thing about a rackmount server with the following spec :-
Jetway JNC92 1.6GHz Dual Core Atom Motherboard with 1x Gigabit LAN; 2GB DDR2 667 Memory; Couple of 80GB HDs.
I will only have a maximum of 2 concurrent calls and will be using the commercial Digium G729 codec.
Will this hardware be sufficient ? Would I get away with 1GB RAM and a single core Atom and save some pennies ?
Instead of the two 80GB HDs I have also thought about a single 30GB SSD as voicemails etc will be stored on another server. Thoughts ?
