Lack of OpenZAP support might be an issue, I assume that would be required to connect to an onboard analogue port... I assume I could just install Debian or another distribution instead though.

This is another distribution I found: http://linux.voyage.hk/ It comes with Asterisk out of the box, although I suspect it wouldn't be too hard to get Freeswitch working instead. -- Brian May <brian@microcomaustralia.com.au>

Hi, you could build an "embedded filesystem" using one of these great tools: - buildroot crosstools-ng - ptxdist - moblin2 - clfs The one i prefer is buildroot because is simply, flexible and fast to build a root filesystem: to setup a minimal system, once you builded the toolchain using crosstools-ng, you need only a couple of hours! It support a lot of hardware platform and br mailing list is VERY active! If you need to use the hardware supplier toolchain you can, just set it instead to build one with crosstools-ng! Freeswitch uses threads a lot, more than asterisk i think, so is preferable to use glibc or eglibc (more configurable than glibc, but essentially the same) instead of uclibc because these libraries are great for embedded hardware but support only old style threads (linuxthread instead of nptl). You can use busybox as base for a lot of stuff and then build what you need (php with fastcgi, lighttpd [althought i prefer nginx], sqlite, lua and so on). I'm doing some job integrating fs with an own software, so i'll start to work on it, probably, the next year, at the end of first quarter or at start of the second, until that moment i'll use a shrinked down ubuntu 8.04 to fit it on a 4gb cf. (i got my alix board a couple of days ago!). However i've used br in a couple of personal project and to help my brother at university (needed to setup a system on a xilinx virtex ii board) If you prefer something more well tested you can give a try to ptxdist or moblin2 but them are harder to use and configure althought them works better!

I think I fixed the spandsp cross compile issues tonight, but I suspect there is a good chance that I broke other builds in the process. I also did a bunch of work to make the OS X Snow Leopard build cleaner today. Testing would be much appreciated on both. Mike On Dec 9, 2009, at 10:47 PM, Kristian Kielhofner wrote:

Brian,

I have been making efforts to fully support FreeSWITCH in AstLinux. Our primary targets are low powered x86 boards like the Soekris and Alix. x86, powerful enough, cheap enough (as low as $100), and about 12 watts. Not bad.

The Soekris net5501 and standard case will (I believe) take a full height card. Then again you could use any board and get an external SIP gateway (ATA). We don't currently support OpenZAP with FS in AstLinux but I'd love to add support for it eventually.

I'm currently working with the FS devs on getting some issues in trunk resolved to get cross compiling working again. Until then you can find ISOs with FreeSWITCH and AstLInux here if you'd like to check it out:

http://mirror.astlinux.org/freeswitch/daily/

Let me know what you think.

Hello,

I asked this question on my local linux user group mailing list, and got the recommendation to ask here.

Anyway, at the moment I am running Asterisk on an IP04 embedded system. http://www.rowetel.com/ucasterisk/ip04.html

It works well most of the time, however there are some bugs that do, under circumstances lead to less then desirable behaviour (such as on some occasions which I don't fully understand sometimes the remote system fails to generate any audio packets when there is no audio - almost like silence suppression was supported by the remote system - and asterisk fails to generate any audio packets in return; on another slower computer running the same SIP software and on the same network everything works fine; as far as I can tell the software - twinkle - doesn't even support silence suppression).

I suspect at least some - if not all - of the issues I have encountered may be resolved with Freeswitch, however I don't really want to replace my small, energy efficient, embedded system, with a large, power hungry computer system. Overkill.

An added complication is I need at least 1 analogue port to connect to the Australian based telephone line (2 ports exchange ports and 1 extension port would be ideal but not essiential).

Unfortunately, I have been told that the IP04 hardware isn't compatable with the requirements of Freeswitch. Such as not having a MMU. So there doesn't appear to be much effort porting Freeswitch to IP04 as a result.

I do have a spare TDM400p card, although as it is full height, suspect this isn't going to help.

Are there any other good alternatives?

Thanks. -- Brian May <brian@microcomaustralia.com.au>

A board with an atom 330 on it would probably do the trick for you.  There are a few made by Intel and Supermicro that look pretty nice.  There were some other people on the list looking to use them.  Maybe we can get a report from someone.

Intel came up with the D945GSEJT, which is totally fanless and has an embedded DC/DC, so all you have to add is an external AC/DC power brick, some RAM, a PCI riser to save space, and either a hard-disk or a CompactFlash + IDE adaptor. I'm thinking of building one with a Digium-compatible PCI card.

The 330 boards are a little more power hungry but you get a dual core 64 bit processor. As far as I'm concerned the performance increase is well worth the extra money. You still well below the power consumption of any other 64 bit dual core machines. http://www.newegg.com/Product/Product.aspx?Item=N82E16813121383 --FC

ok, but how much smultaneous calls did you get on an alix board using astlinux... for istnace, this is the question? T. On Thu, Dec 10, 2009 at 5:12 PM, Kristian Kielhofner < kristian.kielhofner@gmail.com> wrote:

While these are low power when compared to traditional desktop/server systems, they're not what I would consider to be embedded. The CPU requires a fan (embedded no-no) and between the chipset and CPU they draw several times more power than a traditional embedded system. The ALIX and Soekris boards run with 12 watt power supplies (12v, 1 amp). The Atom 330 alone can draw 8 watts. This is still impressive for a processor of this class but it's not what I would consider to be embedded, yet...

I think of embedded systems like this:

Blackfin - Very low power, good performance (especially for DSP), very difficult porting (usually) ARM/MIPS - Very low power, decent performance depending on application, mild difficulty in porting X86 (Geode, etc) - Pretty low power, decent performance, relative ease in "porting" (often none) Everything else - You should probably call it an "appliance", not an embedded system

With the correct target application and design ARM and Geode systems can provide more than enough CPU power for many, many practical applications.

Ok, found the net5501: http://www.yawarra.com.au/hw-net5501.php And here it is assembled for you: http://www.yawarra.com.au/product.php?productCode=HW-NT55 I am not quite sure on one aspect, for extensions to work the TDM400P card requires a IDE style power connector that provides 12V, 5V, etc. Presumably this would be possible somehow with the net5501, because those voltages would be required for a HDD which seems to be supported.
