I need to set up some toll restrictions, ie 2 extensions can only dial local and toll free. So the procedure would be to set outbound calling #401 to local only, then use #407 to add 1800, 1866, 1877 and 1888 to the allowed list as I understand? For local only does the system just assume any 7 digit number is a local call or is there more? I assume 911 must be only in the emergency number list #406?
