This is the same situation that I have faced for a while. There is no
middle ground solution that makes economic and functional sense. When I
find a standalone 4 port FXO adapter that works well over SIP with *
then we'll have a solution. If Digium delivers upon their long promised
FXO daughter card for the TDM40 that could also be attractive.
