Server for trixbox

[localzuk]

I am now sorting out a full job spec for rolling out a VOIP system in the school and I have pretty much got all the prices I need.

 

The problem I have is redundancy, power usage and speed at which things can be fixed.

 

I would prefer to use a low power server, as this will last longer on a UPS if the power goes off, so I am speccing up a pair of mini-itx servers which I can swap in and out of their tasks should one fail.

 

My question is, what speed processor ITX board/cpu should I be looking at?

 

It will be a system which should run upto 40 extensions (maximum of 10 concurrent calls within the system), and 4 external lines (3 voice, 1 fax dedicated). We will also have on hold music and some other fun stuff like an IVR and the occasional conference call.

 

Oh, and I intend to use a CF card to host the system on to reduce power usage further and to increase the ease of switching servers over.

 

Any hints would be helpful.

Rather than manually swapping in a new server why not look into asterisk clustering?

 

Will you be doing a paper on your installation?

I will be documenting everything I do, yes. We need to have a complete paper trail so I don't get hung to dry if something fails.

 

How do you asterisk clustering?

Specifically, I'm having a look at these: http://linitx.com/product_info.php?cPath=12_138&products_id=1184

 

2Ghz Via C7 processor and I'd slap 1GB RAM in it, a 4GB CF card and possibly an 80GB SATA hdd for voicemail, all nicely placed in a 1U case with a 180W PSU.

Looks good, I love it when you enlarge the top pic and the label on top of the ps/2 connectors reads chufon

Hmm, I've had a look at clustering and it seems that it would push the price of it up considerably - and as they have me onsite everyday it wouldn't be justifiable to buy a switch with AB Failover either...

You can do simple two node fail over entirely in software with heartbeat.
