Network Configuration of the IP Phones
Configuring 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.
Configuring DHCP
You can enable and disable DHCP using the configuration files, the IP phone UI,
or the Aastra Web UI.
Note:
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.
Configuration Files
For specific parameters you can set in the configuration files, see Appendix A, the section,
