QUESTION Amfeltec Piranha USB-FXO?

[boeingpilot]

I have a customer with a really small requirement (3 extensions), buts who would like to advantages of a PBX vs. a key system. I'm thinking of using a Raspberry Pi for them, but need an easy way to get FXO's connected.

Found this from Amfletec (http://amfeltec.com/products/piranha-usb-fxo-adapter/). Looks as if it would fill the bill, but...

-- Anyone have any experience? I remember trying the Sangoma USB-FXO, which was really a work in progress, and would never ever try in production again

-- If so, anyone know if it works on an ARM based system?

I do expect the current draw to be more than the pi can provide, so a powered hub is in order

I'd just use an Obi110 (or a few if you need less than four trunks). I had (and probably still have in a drawer somewhere) one of Sangoma's USB FXO units. Hated it - never worked right, and the audio quality was beyond unusable.

Yea, the OBI is reliable, but I'm liking the idea of no additional power 'warts', and the smaller footprint.

Additionally, on i86 based systems, this would be perfect for the one 'real' line.

Maybe I'll just go and buy one to test and report on

Yea, but I won't be using it only with Pi's

I tested. It works. I may help you to configure it.

I have just received the Amfeltec Pirahna usb - fxo. I will be using it with FreePBX. I have it plugged in, but I'm not seeing any FXO ports. What else do I need to do to set it up? Nothing came with the hardware...
