Talkswitch 48-CA/CVA, 24-CA manual Public WAN IP Address, Current public WAN IP address

Unit IP Address:

Assign an available static IP address to each unit (1-4). If you use a DHCP server, you have to reserve an IP address for each unit. To reserve an IP address, you need the MAC address of each unit. To view the unit MAC address, click the View System Information link on the About TalkSwitch configuration page. For more information, see 2.1.1 The configuration screen on page 29.

Subnet Mask:

Enter the subnet mask for the LAN. This address determines what subnet the specific addresses belong to.

Default Gateway:

Enter the IP address of the gateway on your network. A gateway is a hardware device (i. e. router/NAT) that connects the office network to the Internet. The gateway allows you to share a DSL, cable modem or other Internet connections with all of the computers and IP devices in your office network.

Preferred DNS Server:

Enter the IP address of the preferred/primary DNS server. DNS is a service that is used to resolve a domain name to an IP address.

Example: A DNS server is used by your web browser to resolve www.talkswitch.com to an IP address such as 64.26.166.52. For more information, see Chapter 5: VoIP Information on page 155.

Alternate DNS Server:

Enter the alternate/secondary DNS servers IP address if applicable.

Public WAN IP Address

Type of public WAN IP address for Internet Connection:

This field is set to dynamic by default. The unit checks the public IP address every 5 minutes. If it changes, it automatically updates to the correct information in order to manage VoIP calls properly.

The dynamic setting will not work in closed network environments. In a closed network environment, change the field to static and enter the appropriate IP address. If the unit is not behind a router, enter the IP address of the unit acting as the local proxy.

Current public WAN IP address:

For the dynamic setting, this entry shows the current public IP address and is not editable. For the static setting, enter the IP address or the FQDN of your location.
