If you do not have a DHCP server, the following fields need to be completed
if you plan on using the VoIP capabilities.
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 31.
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.
