Configuring Network and Session Initiation Protocol (SIP) Features
Configuring the IP Phones
• 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.
Note: 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.
