Err, yeah, the PAP2 only has FXS ports.

It would do, if they were different impedances.
This isn't a normal audio amp, it expects to be plugged into an
extension port of an analogue phone system (which sees it as permanently
off-hook).

I'm not there to test any of this, but I did plug it into an FXS port of
the AG-468 that's there to see if it sounded okay, and the whole place
rumbled with the configured dialtone :-)

So hopefully the same will apply with a PAP2.
