The OpenWRT (on whatever supported "router" hardware) + SPA-3102 is a
pretty decent combo. You can reinvite the traffic between the FXO and
FXS (g711 only) and get good quality without even taxing the router.
FYI, a WRT54G had no problem running asterisk 1.2.x with 4 concurrent
channels (g711, no transcoding, just RTP proxying).

I'd look into something like that. And you can "expand" it fairly
easily by adding another SPA for a second line.
