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,
