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.
