cool !!! ... I am surprised you had issues with the USB CDROM boot and am not sure what was going on with that ... but you were able to boot off a USB flash drive ... hmmm ... that's a bit strange but seems you managed to find a work around ... your method of getting the image onto the DOM makes sense and I suspect you will be much happier booting from the DOM than you would be if you stayed with the USB flash drive ... on my own systems, I find the DOM is WAY faster to boot ... I think if you crack the case on the thing, you will find that it has a standard 40 pin or 44 pin IDE hard drive interface in it ... I always assumed that if I could not figure out any other way to do it, I would just set it up to run with the cover off and physically connect both an IDE CDROM and the DOM ... figured the worst case would be getting hands on an IDE gender changer so I could plug the DOM into the female cable connection instead of directly into the m'board ...

Burn an Usb key with astlinux i586 image Setup the thin client to be able to boot thru USB Plug it into the thin client and start with usb boot option Create a new partition on the usb disk with at least the size of "AstLinux-0.4.4-i586.img.gz" Copy "AstLinux-0.4.4-i586.img.gz" on it (I have done it with winscp from another comp) and finally "gunzip -c /PathTo/AstLinux-0.4.4-i586.img.gz > /dev/hda Unplug the usb key and reboot. That's it Have Fun, I personnally bought a 5520 for 200€, big deal for a 800Mhz It's possible to find them easily around 250€ Olivier Michael Graves a écrit : I simply burn the Generic 586 image to a USB key, then create two additional partitions. The third partition holds the config data & VM. I could not find a convenient way to burn the image to the 256 MB DOM card that's fitted internally so I removed that module. If you can rig a wiring harness to connect that DOM to an IDE controller you should be able to burn the image to it instead of the USB key. Michael --Original Message Text--- From: olivier.taylor Date: Wed, 06 Dec 2006 17:43:26 +0100 just seen you use an hp thin client, I just got a hp 5500 via 800Mhz one. what's the way to install astlinux on it? Soekris as you said is not powefull enough for the transcoding when having more than 2 or 3 simultaneous calls. Regards, Olivier Michael Graves a écrit : Carla, There can be both performance and licensing issues. G.729a is the most widely used high quality compressed codecs, but you needs to buy licenses from Digium...$10 per stream. Digium provides this as a service, passing the license fees on to the patent holder. It's CPU intensive so a Soekris Net4801 will only encode/decode two calls using G.729a. I presently run Astlinux on a H-P T5700 thin client with a 1 GHz CPU. It can transcode 5-6 calls. See voip-info.org for "system dimensioning" to see details on larger systems. There are DSP cards that can add to suitable hosts to move the transcoding activity off the host CPU. These are good but costly solutions. As a practical matter if you're dealing with known ITSPs or peers then you should be able to limit the codecs required and G.729s may not be an issue. In fact ILBC may not be an issue. G.711a/u and GSM get it done for a lot of providers. Michael On Tue, 5 Dec 2006 22:40:40 -0800, Carla Schroder wrote: Gah, so it depends on whatever the people calling my network are using? Is there any downside to allowing all codecs, like performance issues? Assume a magical world with no licensing hassles for proprietary codecs. :) On Tuesday 05 December 2006 18:38, Michael Graves wrote: Carla, The system will offer to negotiate a connection with the allowed codecs. If it cannot then the call will simply be refused. You can allow GSM and ILBC as these are royalty free and commonly used. If you find that ILBC calls are poor quality you can always rem out that line later on. Noe also that you can specify the codecs in the general section and also on a per peer basis.

A typical configuration looks like this: disallow=all allow=alaw allow=ulaw What happens when a call comes in that uses a different codec?
