Hi Hooman,

What you probably want is a PRI PBX running Asterisk.

You should either plan to build your own (with the cards you need) or get
one of the low cost options:

   - Allo.com has their Mega PBX with 1 PPR port (
   - Pika Tech has the Warp PBX with BRI (

Both ship world wide. There are other brands and models out there and
depending on where you are located they may be better options based on
shipping etc.

Hope this helps,
