A call management device is connected to one or more internal networks and one or more external networks, and it operates to receive incoming calls or messages from the external networks and make a determination as to whether or not the call is from a qualified source. If the call is from a qualified source, the call is immediately forwarded to a destination device connected to the one or more internal networks, and if the call is from a source that is not qualified, the call is either terminated or the caller is prompted to enter a required response and identification information prior to the call be forwarded to the destination device. |
