Network Configuration of the IP Phones

The network administrator chooses which of these parameters (if any) are 
supplied to the IP phone by the DHCP server. The administrator must configure 
the phone manually to provide any required network parameters not supplied by 
the DHCP server.

You can enable and disable DHCP using the configuration files, the IP phone UI, 
or the Aastra Web UI.

For DHCP to automatically populate the IP address or domain 

name for the TFTP server, your DHCP server must support Option 66. 
Option 66 is responsible for forwarding the TFTP server IP address or 
domain name to the phone automatically. If your DHCP server does not 
support Option 66, you must manually enter the IP address or domain 
name for the TFTP server into your IP phone configuration.

For specific parameters you can set in the configuration files, see Appendix A, the section,
