That is not correct or at best not completely correct.  That is what I would
have believed it to be,  but some passthrus (like the handytones) allow you
 to dial *00 or some other combination to dial out of the PSTN directly.  I 
guess it is possible that the *00 turns off the FXS to allow the straight 
passthru, but even if that is so, the X100p doesn't have an equivalent 
functionality.
