It's exactly how OpenPhoenux started, I'm sure you know?
The initial setup for GTA04a1  is quite similar to the goal you're
heading for, I suppose. In case you're visiting FOSDEM next week, be
sure to visit the OpenPhoenux stand in the AW-building!

You might be missing something. After all, most (if not all) phone
traffic is VoIP nowadays. If you like to connect your VoIP system to the
POTS-network, you need something like a DID- or DDI-number (direct
inbound dialing), something of a bridge between the me at myserver.org-SIP
and the +31nnnnnnnnn number you'd want to give to Dutch acquaintances.
As far as I know, more than one DID-number can point to the same
VoIP/SIP-address, so you can have your friends abroad call for local fees.
That's about as far as my knowledge and understanding reach. (Shameless)
plug: since your email address is in the Netherlands, you might be
interested in Limesco.org, the "open source" mobile phone operator,
where you could run your own server instead of relying on the operators
