When you say the Digital Voice service has to go through the Home Gateway, do you mean the DV must be terminated directly on the DVG-N5402SP? How about customers who are still using the motorola IADs? Does the IAD have to be directly connected to the LAN ports on the DVG-N5402SP? Can the IAD be connected on the LAN ports behind another router that is bridged with the DVG-N5402SP?
Have you enabled DMZ on your D-Link Home Gateway?
For Digital Voice Home service which the service has been tagged to the D-Link Home Gateway, the phone has to be connected to the Home Gateway.
