well, I got the HP working without problems from the dom with no
hardware needs :)
quite easy, thanks to Astlinux to have the essential tools to do that.
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€

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.

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.

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.

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. :)

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.

hey all,
How do you decide which codecs to allow in sip.conf? A typical
configuration looks like this:
disallow=all
allow=alaw
allow=ulaw
What happens when a call comes in that uses a different codec? Any
pointers to a good reference are welcome.
