I've benchmarked an Alix board with a 500MHz processor to 80 concurrent calls handling media. They're the mainstay of my small office VoIp only PBX range right now where I limit them to 60 extensions. (the real limitation on number of calls is their broadband bandwidth). Storing voicemail and call recording won't be an issue for you - but do get a fast CF card. http://unicorn.drogon.net/cutie.jpg What you need to do is learn Linux networking and iptables - then you won't need pfsense, etc. Install a good text-only distribution and you're done. e.g. Debian Lenny in text-only mode. To get he best from the hardware then you'll need a custom kernel, but that's no big deal. However the thing that will kill it is multiple VPN terminations - unless you can persuade the system to use the on-board AES crypto engine, but I regularly use ssh into my systems without any detriment, so you could use OpenVPN, etc. I am considering making my boxes into a router and handle PPPoE too, then they can do proper traffic shaping, etc. They're more than capable.
