I have a quadra 4l and am integrating a Doorbell Fon from homephone.com for a client.
This device needs to be connected to the FXO line. So FXO3 and FXO 4 are door phone 1 and 2 respectively.
In call routing I want to make sure that 911 emergency calls are not routed to these door phone FXO lines.
As I cannot edit the 911 call routing how do I ensure that this call is routed to the PSTN lines on FXO1 or FXO 2.
