No idea, but if you look further afield, if you buy a Sangoma A200 or an
A400 you can have all 12 on one PCI (or PCI Express) slot (the former
taking up 3 Spaces on your PCs backplane and the latter taking up only 1).

If expandability is a concern, an A400 can support up to 48 FXO ports on
one PCI (or PCI-Express) Slot (4 spaces) or an A200 can support up to 24
FXO ports. (6 spaces)

I can't comment on how good they are, I've only got TDM400Ps myself.
