Ppp doesn't attempt to deal with the callback. You need to set up an
independent configuration that will accept the incoming call and
invoke ppp with the appropriate profile. The tricky thing about
doing this is executing ppp with stdin as a readable *and* writable
descriptor. FreeBSD's sh doesn't support <>, but bash does.
