No, that will be the A200, and you do not want that one for sure.
The A400 have four FXS and four FXO.
The FXO will be the PSTN ports, where you attach the dial tones from the phone company.
The FXS are the PBS ports, where you attach phones, faxes or key phone system.
The theory is that you could only make four calls total, betwen the two sets of ports, but I never tried to see what happens if you try to go over .
Anyone tried??????
