Aastra Telecom 57I C53I manual IP Phone UI, Configuring Dhcp

Network Configuration of the IP Phones

Basic Network Settings

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.

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.

Configuration Files

For specific parameters you can set in the configuration files, see Appendix A, the section, “Network Settings” on page A-5.
