Sounds like you want something like the Sipura SPA-3000, which has one
fxo port (pstn), one fxs port and one Ethernet (voip) port. About as small 
as it can get, remotely configurable via a browser, very stable, no
buttons or screens, and a good selection of codecs for adjusting to 
small dsl bandwidth. 

Downside: more config options then you care to imagine; a little 
difficult to initially configure if you're not heavily into voip 
and telephony stuff. About $100 US.

I've never played with a spa-3000 in a nat environment, but since 
several of the itsp's support it, it must work okay.
