System: Panasonic KX-TD1232 v4
Voicemail: KX-TVS75
Phone: KX-TD7425

I have a bare bones 1232 which I am installing in a school. I want to set these phones up as an intercom system so the office can dial one of the classroom phones and it will automatically answer no matter what. (instead of ringing and the teacher having to pick up the phone)

I would like to make it so each of the classroom phones has the auto-answer permanently on. In other words if someone pushed the Auto Answer button it would not turn off.

Is there any way to do this with the current phones? If not are there other phones that this feature can be set to stay on? We have 12 classrooms total. I am open to any suggestions. I even considered physically opening each of the phones and disabling the auto answer button. (I just don't know how I would turn it on after that though because it seems like every time the phones gets power cycled auto answer defaults to off.)

Thanks all!
