asterisk users - Nov 2009 - Asterisk on a MiniITX board+Atom1.6 2gb+Sangoma USB?

Hello,
does this sound as a good combination, mini-itx board with Atom
dual core 1.6ghz 2G ram and a sangoma USB?

For a setup with PSTN for incoming and IAX2(alaw/gsm) for outgoing calls.

- Would you say its a good choice from a hardware perspective?
- Roughly how many concurrent calls would one of these be able to handle?

Regards,
Veselin K

Probably as much as your bandwidth can handle. Check ont the voip wiki
(http://www.voip-info.org) and use the search term "dimensioning."
You'll find lots of older references to systems running at 400 MHz - 1
GHz passing many calls as long as they don't transcode between codecs.

I myself have a little FIT-PC2 that I'm starting to use for Asterisk.
It's basically a netbook, like the hardware you describe, but tiny and
very low power. Ideal for a small office or home office.

Hi,

I've been running Asterisk on a VIA C7 Nano board for nearly 2 years. We 
have two IAX2 numbers inbound and an IAX-IAX trunk to our other office, 
an X100p for an analogue line backup and various sip extensions.

The box also acts as my development server, home file server and plenty 
of other stuff too. Oh, yes, it's downclocked to 1Ghz and has 1GB of RAM.

Processing capacity is not really the limitation. The speed of your 
upstream broadband line is the most restrictive aspect.

We don't do any transcoding it's all G.711.
