I know that some if not all Continental Express ERJs have a phone at the bulkhead of seat 1A.
Aaah, that is the Flight Attendants phone so they can talk to the flight deck and make announcements. It is not a air to ground phone. Every single ERJ has a phone in that location, some ERJ-145's will even have a FA
Phone mounted to the aft bulkhead.
