Would anyone have recommendations for a small or embedded
system suitable for running Asterisk on? Ideally, we'd like two boxes:
- One using compact flash, and is fanless, with rapid booting.
- One with a hard disk for voicemail, call recording, etc.
Preferably they would be capable of bridging 60 calls Zap-Zap
or Zap-SIP, but we're willing to consider less powerful
systems. The ability to take a single Digium card is desirable.
We've recently ordered a pair of these:
http://www.soekris.com/net4801.htm
Which have a standard PCI slot into which I'm hoping a TDM card will work.
Their Belgian distributor (kd85.com) appears to have a nice range of
expanded cases that might (hopefully) take a TDM card. I'll find out when
they arrive I guess.
I'm not sure whether a 266Mhz processor would stand a hope in hell of
running 60 calls though - I'll leave that one for someone else to answer.
Fortunately our requirement is only for 4-6 concurrent calls.

Chris,
About the TDM card... Several things:
- No FXS ports - the Soekris doesn't have the means to provide ringing
voltage for the card.
- Even four concurrent calls might be tricky. Even if you aren't doing
transcoding, you will still probably have to do echo cancellation, which
is CPU intensive (especially on the Soekris)!
- The case. You already know about kd85.com. But 30 euro is a little
expensive for their full height PCI case...
As far as 60 calls. Maybe SIP to SIP, with re-invites and even that is
pushing it. Overall, a Net4801 would not be appropriate for what the OP
is looking for.
P.S. - You should run AstLinux on your net4801:

P.P.S. - I created AstLinux, and it rocks ;)!
