VoIP Device and D-Link Router Configuration
« on: May 05, 2014, 10:13:35 AM »

Overview:
This information is to help users with dedicated VoIP devices, i.e. Att Microcell, NetTalk, or Ooma VoIP phone devices to be set up and configured with D-Link routers connected to ISP modems.

Preferred hardware connection method:
This configuration assumes that users have a single NAT condition and the D-Link router carries this NAT condition:
ISP Modem (stand alone or no built in router) LAN wire connected to yellow Internet or WAN port on router>D-Link router (DGL/DIR series)><VoIP Device LAN wired connection to one of the black LAN ports (1-4) in back of the D-Link router or connected to a external Gb network switch that is connected to the back of the D-Link router.

  • If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of 192.168.0.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to 192.168.1.1 or .0.254.
    Example of a D-Link router configured for PPPoE with ISP Modem bridged: PPPoE Configuration on Router

Router Configuration:
1. Log into the routers configuration page and navigate to the Setup/Networking section.

2. Reserve the IP address for the VoIP device that is listed on the DHCP Dynamic Clients list. Select Reserve link on the same row as the VoIP address device is listed. This will auto fill in the ADD Reservation section above.

3. From the Add Reservation section above, give a new host name for the device for east of identification.

4. You can use the detected IP address for the device or change the IP address to a different one here as well. Be aware that any QoS rules that is pre-configured under Advanced/QoS on DIR series routers can impact the VoIP operation. We recommend not using any QoS features to get correct VoIP device operation. If you do have QoS rules configured, reserve an IP address outside of any QoS rules that maybe setup already on the router.

5. Once the IP address and host name have been configured, Select ADD then Save Settings. If the router asks you to reboot now or later, choose later.

6. Navigate to the Advanced/Firewall section on the router. Find the DMZ section under the Firewall section. Input the IP address that was reserved for the VoIP devices in the DMZ IP address box. Select Save Settings. This time select Reboot Now.

7. Power off the VoIP device until the router reboots, then power ON the VoIP device.

Test the VoIP device with a phone and check to make sure that you hear ring tones and audible voice from the receiving phone or called phone number and the remote phone can hear your audible voice.

Test to make sure that the VoIP device is receiving phone calls correctly. Have someone call your number from a remote location.

If configured correctly, all voice calls should be correct while connected to the VoIP device.

NOTES:
My personal experiences are with the Att Microcell and various D-Link routers. Using the Reserved IP address and the DMZ feature on the router helps in the configuration and operation of the VoIP and there shouldn't be the need for any other configuration on the router.

If this setup configuration process fails, please post in the model router forum for your product and we'll help you troubleshoot the problem and help you get the VoIP device going if we can.

Thank you.
