This sounds pretty cool... could you share some config files, maybe 
stick them on the wiki somewhere? Or if you want you can send them to me

document it and write a commented howto in exchange for the community to 
enjoy.

Well, if you can point me to a place where I can buy Sipura-3000-like 
devices which support IAX2
I'll jump on it immediately.

I think farfon is building something called the farata but I don't think
