My (simple) solution was to put an * server at each site with an 
extension from the PBX connected to an * FXO port. Users dial the 
regular pbx ext to access the * pbx and then after dialling the remote 
office extension that they want the call is forwarded to the other end 
using an IAX connection.

You could do something similar using two FXO cards at each end.
