Network
The following paragraphs describe the network parameters you can configure on
the IP phone. Network settings are in two categories:
• Basic network settings
• Advanced network settings
Basic Network Settings
If Dynamic Host Configuration Protocol (DHCP) is enabled, the IP phone
automatically configures all of the Network settings. If the phone cannot populate
the Network settings, or if DHCP is disabled, you can set the Network options
manually.
• DHCP
Enables or disables DHCP. When enabled, the phone may populate the
following fields as read-only: IP Address, Subnet Mask, Gateway, Broadcast
Address, Domain Name
Servers (DNS), Trivial File Transfer Protocol (TFTP) Server, and Timer
Servers.
• IP Address
IP address of the IP phone. To assign a static IP address, disable DHCP.
• Subnet Mask
Subnet mask defines the IP address range local to the IP phone. To assign a
static subnet mask, disable DHCP.
• Gateway
The IP address of the network’s gateway or default router IP address. To
assign a static Gateway IP address, disable DHCP.
Note: Specific parameters are configurable using the Aastra Web UI only
and are indicated where applicable.
Note: For DHCP to automatically populate the IP address or qualified
domain name for the TFTP server, your DHCP server must support
Option 66. For more information, see Chapter 4, the section,
“DHCP” on
page 4-4.
