Deployability Features

Server and Protocol Identification via DHCP Feature

The IP Phones now support additional download protocols according to RFC2131

and RFC1541 to support DHCP option 66.

Option 66 is part of the DHCP Offer message that the DHCP server generates to

tell the phone which configuration server it should use to download new firmware

and configuration files. In addition to supporting the IP address of a TFTP server

in this field, the phone now supports a URI format for specifying the other

configuration server types.

Your DHCP server configuration file, such as the dhcpd.conf file, may include one

of these lines to configure the configuration server protocol and the server details.

Protocol Format Examples

HTTP http://<server>/<path> option tftp-server-name “http://192.168.1.45”;

option tftp-server-name “http://192.168.1.45/path”;

option tftp-server-name “http://httpsvr.example.com/path”;

HTTPS https://<server>/<path> option tftp-server-name “https://192.168.1.45”;

option tftp-server-name “https://192.168.1.45/path”;

option tftp-server-name “https://httpssvr.example.com/

path”;
