2.If you selected Dynamic public IP address, enter the Fully qualified domain name (FQDN). Get the FQDN from your ISP.
A DDNS (Dynamic Domain Name Service) provider such as www.dyndns.com matches your dynamic IP addresses to your FQDN, so your TalkSwitch VoIP network or external IP phones will continue to work when the IP
address changes.
If your router supports DDNS, ensure it supports your DDNS provider, and configure it to update the DNS servers.
If your router does not support DDNS, download one of the applications specified on www.dyndns.com. To update the DNS servers, the application needs to run on a PC connected to the same LAN as the TalkSwitch system.
3.If you selected Static public IP address, enter the Current public IP address from your Internet Service Provider. Leave the Fully qualified domain name box blank.
If the TalkSwitch unit is not behind a router, or if a private virtual network is used, the public IP address is the local IP address of the TalkSwitch unit acting as local proxy.
Note that it will take up to one minute for the new static public IP address to take effect.
4.Record the Current public IP address or the Fully qualified domain name.
If you are setting up an external IP extension, you will need the public IP address or FQDN of the TalkSwitch system.
If you are setting up a TalkSwitch VoIP network, the TalkSwitch profiles of the SIP clients must be configured with the public IP address or FQDN of the SIP server.
CONFIGURING THE ROUTER
The Router Port Forwarding area of the IP Configuration page displays the type of gateway device (i.e. the type of router), the IP address of the gateway (i.e. router), and whether router configuration is required.
A router is a gateway between the local area network and the Internet. Most routers have a firewall to block unwanted data from the Internet. For voice data to reach the TalkSwitch system through the firewall, port forwarding is required. Port forwarding allows the router to map ports to the IP addresses of the TalkSwitch units. Valid Internet data will use the ports to go through the firewall to the TalkSwitch units.
