• Lease:
The amount of time a DNS Server reserves an address it has assigned. If the address isn’t used by the Host for
a period of time, the lease can expire and the address can be assigned to another host.
• MAC Address:
MAC stands for Media Access Control. A MAC address, also called a Hardware Address or Physical
Address, is a unique address assigned to a device at the factory. It resides in the device’s memory and is often printed on
the outside of the device. It is used by Routers to send network traffic to the correct IP Address. Example 00-0B-82-12-0C-
48
• Network Administrator:
The person responsible for setting up and maintaining a network. The network administrator’s
job includes making sure that space is available on the file server, that the file server is backed up regularly, that new
employees can access the network, troubleshooting network problems and other tasks.
• Physical Address:
See MAC Address.
• Router:
A device that forwards data from one network to another. In order to send information to the right location, routers
look at IP Address, MAC Address and Subnet Mask.
• SIP:
SIP (Session Initiation Protocol) is an IP telephony signaling protocol primarily used for VoIP calls but which can
also be used for video or any media type. SIP establishes sessions using these technologies and deploys them over IP net-
works, enabling service providers to integrate basic IP telephony services with internet, email and chat services. SIP servers
also support traditional telephony features like call forwarding.
• Static IP Address:
A static IP Address has been assigned manually and is permanent until it is manually removed. It is
not subject to the Lease limitations of a Dynamic IP Address assigned by the DNS Server.
• Subnet Mask:
A type of address filter used by Routers to send data to the correct location. This is one of the pieces of
information needed to manually set an IP Address.
• VoIP Gateway:
This is a generic term that covers a variety of devices, all of which at some point act as digital-to-analog
converters. The essential function of a VoIP gateway is to convert an analog voice signal to digital information so it can be
sent out on a network, making VoIP possible. This conversion function is often built into other devices like routers or
cable/DSL modems. If the gateway’s only function is to convert digital to analog and vice versa, it is called an ATA.
• WAN:
Wide Area Network. A WAN is a network comprising a large geographical area like a state or country. The largest
WAN is the Internet.

1.
Let your network administrator know that you would like to install the
ATA-100
and ask him to supply you with a static
IP address. If this is not a possibility, the
ATA-100
can still be installed with a dynamic IP address, but a static address
is preferred.
2.
The
ATA-100
is manufactured by Cortelco with the model number 8211. Download the Cortelco 8211 manual, which is
available at www.cortelco.com. Follow the instructions provided in the Cortelco 8211 manual. The information that
follows expands on Cortelco’s installation instructions.

• The Cortelco leaves the factory with a default static IP address of 192.168.1.100, and it is likely that this address is
not in the same subnet as the static IP address you got from your network administrator. If this is the case, when you
open your web browser to the default address, you will not reach the programming page. To work around this, follow the
instructions to use DHCP to get a dynamic IP address, and write down the address as it is spoken in the handset of the
phone by the Cortelco. Open your browser to this address, andadd “:9999/“ (the instructions show an example). When
the login page appears, you will need to enter a user name and password (the default settings are in the instructions).
When the programming page appears, mouse over “Network” on the left, about halfway down the page, then click on
“Network Settings”. At the top of the Network Settings page, by “IP Type” click on “Fixed IP”. On the next line, in the box
labeled “IP” enter the static IP address you got from your network administrator. Click on the “Submit” button at the bot-
tom of the page. Then near the bottom on the left click on “Save Change” and when the “Save” button appears, click on
it. The Cortellco reboots automatically; give it a minute or so. You have successfully assigned a static IP address to the
Cortelco.
• You can change any of the settings on the programming page by opening your browser to the IP address you just set.
Just remember to save changes and wait for reboot.
