Configuring Network and Session Initiation Protocol (SIP) Features

•

HTTP Server

•

HTTPS Server

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.

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.

The IP Phones support download protocols according to RFC2131 

and RFC1541 (TFTP, FTP, HTTP,. HTTPS) 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.

For DHCP to automatically populate the IP address or domain name for 
the servers, your DHCP server must support Option 66. Option 66 is 
responsible for forwarding the server’s 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.
