Probably a dumb question but I am actually having a pain in the ass time with this one.... Got a car with remote machine room, inspector picked up on no 2 way communication... honestly havent had an inspector request this in years so its been a while but we used to use NuTone intercoms that we could wire up using the tcable. Having a tough time now finding a communication system that has a speaker for the car side that does not require a push to talk. Wondering what others use for this? is there some system we can just connect to the phone line in the controller so we can speak to the passenger through the in car phone? (being able to call into the phone with a cell is not acceptable any longer even though everyone has one).
