That's correct, but I can't think of a situation where you would have to fly from the FAF to the MAP without being able to get a word in. In all likely hood, you would be able to talk to the controller within 30 seconds of passing the FAF. You aren't at the MAP yet, min vectoring altitude won't be an issue. Odds are your last clearance was "descent maintain X, intercept the localizer." If somehow you can't get reach the controller by the time you get to the MAP, execute the missed.
