Low Power CPU?

What is a good low-power cpu to run asterisk on? The system I’m setting up will only handle maybe 5 calls maximum, maybe a few more in the future using the G.711 codec.

I also need to build a backup server running Linux HA in another location that will not do anything except activate Asterisk if the main server goes down (due to a power or internet outage). The backup server’s configuration file will tell all calls to be forwarded to a cell phone.

I found this page that lists several processors, and this page that has a setup that looks like it might work, but it seems the AMD Geode is an embedded processor, and I wasn’t sure if this would work for trixbox?

I’m fairly new to processors and motherboards, so I’m thinking I should stay away from embedded processors for now, and maybe just go with a ultra low power mobile processor in a desktop motherboard? Can I do this? Our setup is entirely VoIP and has no Digium FXO or FXS cards. Price is a factor too, I’d like to keep the box as cheap as possible.

Take a look at the Jetway 2.0GHz Mini-ITX boards, they seem to be good. I have one (the 1.5GHz versioin)that I used as a test box for a Trixbox build and it worked pretty well, however I never did any transcoding, but I don’t see this as a problem for you since you are not running a call centre. These boards carry a VIA C7 processor which use about 20W of power.

What about the Digium Asterisk Appliance?


Not sure it has been officially released but it should be soon (I would imagine as soon as AsteriskNOW is released)

amcmillan: Thanks for the tip. I’m not sure if the Via C7 will be fast enough, but I’m going to go to Wal-mart and give this computer a try: walmart.com/catalog/product. … id=5673669

They don’t give any specs on how much power it uses, so I’ll have to use a kill-a-watt meter to figure that out. I know the Via C7 uses a ridiculously low amount of power. Too bad Wal-mart totes it as an “energy efficient design” and then bundles it with an energy hogging CRT.

swaterhouse: thanks for this link. I hadn’t seen this before. I’ll have to do more research on this device!
