Trixbox CE on Embedded Alix Success
Submitted by dustobub on Wed, 02/13/2008 - 3:00pm.
I just wanted to let people know that I successfully and easily installed Trixbox CE onto an Alix 2C2. If you don't know about the Alix boards they are the successor the WRAP boards and run an AMD Geode LX800 processor, 256mb ram, 1-2 MiniPCI slots, 1-3 Lan ports, and cost under $140. They have been primarily used for firewalls/routers/access points although there are a couple of Asterisk projects designed with embedded hardware in mind (Askozia, AstLinux).
I tried both Askozia and AstLinux and while they both show promise, neither of them provide the polish or amount of features that Trixbox provides. So I looked for someone who had installed Trixbox on an Alix, or any embedded platform, but could not find any info. I tried a few things that didn't work out, but eventually came to a simple solution that works 100%. Here is what I did:
1. Download latest Trixbox ISO
2. Download and install latest Vmware Server 1.x edition (do not use the new beta 2.0)
* I used a 4gb Microdrive however a Compact Flash card would work, although I would be careful with the limited write cycles they have.
3. Plug in your compact flash or microdrive into a usb reader. Open Vmware server and create a new custom virtual machine (Linux 2.6kernel, 256mb ram, 1 serial port, 1 usb port, and the same number of LAN ports that are actually on the Alix). The most important part is to tell Vmware to use the PHYSICAL drive that you inserted into the usb reader. Be careful to not pick your OS hard drive as it will certainly corrupt it. Tell Vmware to use the Trixbox ISO as its cdrom.
4. Boot the virtual machine, and install Trixbox.
5. Once Trixbox is installed, let it boot up and login. Then follow the instructions on this page to get your serial console working.

6. Once this is done you can go ahead and configure the Trixbox while still running in the virtual machine, or you can wait till you transfer the hard drive to the Alix.
7. Turn the virtual machine off, and then remove the usb reader. Install the microdrive/CF into the Alix, plug it in, and voila, you have a fully functional embedded Trixbox.
I have been running this exact setup for about a week now and it is working perfectly. I have around 15 extensions, 1 trunk, 1 inbound route, 1 outbound route, 2 IVRs, Voicemail, VM Email notifications, Paging, and it all works perfectly. I have tested it with 2 simultaneous
external calls and it works fine. I think there is enough power to handle 4-5 simultaneous external calls, any more and you will most likely have issues.
I would recommend this setup to only residential/SOHO setups or extremely small businesses due to the hardware's performance limitations. However, for $125-$140, you can not beat the price, the size, or the functionality.

I have create a wiki entry with my full list of instructions. It can be found here:

I am VERY interested in doing this

I run an install of Trixbox at home since the old A@H days. I have about 7 extensions and we normally never go over two simultaneous calls and I use ulaw for everything so I don't normally transcode.
Can somone comment how well this works? I use an ALIX board to run pfsense today and I have a spare microdrive so all I need is another ALIX board. But I'd hate to do this and find it really doesn't work well - choppy sound, etc.
So would it work well for my home??

I have been running my Alix 2c3 with Trixbox 2.6.0.7 full time for a little over a week now and am impressed.
Boot up takes about 2.5 minutes using a Seagate 8GB microdrive. I am currently shopping around to find a good deal on a 4+ GB CF to replace the microdrive.
Here is the "show translation" output (reason why you DO NOT want to transcode):

As you can see, the processor is just not fast enough to do transcoding.
There is also a longer post dial delay when using an Alix, as its slower processing call routing. I would estimate about 9 seconds PDD. I suppose this would vary with different outbound routing plans.
Backups are VERY easy with a 2+ GB USB thumb drive:
mount /dev/sda1 /mnt/usb
dd if=/dev/hda bs=1k conv=noerror,sync | gzip -c > /mnt/usb/trixbox-backup.img
umount /mnt/usb
But call quality sounds very good. It is silent, generates very little heat, and probably uses very little electricity (I will need to hook it up to my kill-a-watt to get an exact reading).
I believe it is a perfect fit for your home, as long as you can handle a little longer than normal PDD. Let me know if you have any other questions.

Thanks. I'm glad I found a way, with my limited VOIP knowledge, to finally give back to the trixbox community.
As far as some more hard information:
I just plugged the Alix into my kill-a-watt, here is some power consumption data:
4-6 watts or 9-11 VA
0.08-0.10 amps

I finally was able to get hold of a PC with VMWARE, I followed the instructions, but is not booting
This is the message i get on the serial console:

and stops here....
Any Idea?
