4.2. Configure the Cisco 7940/7960 SIP Telephone
Cisco 7940/7960 SIP telephones can be configured using two methods:
1. Configuration files downloaded from a TFTP server specified via DHCP at boot time.
Two such files are installed on the TFTP server: a default configuration file containing
parameter settings that apply to all phones (SIPDefault.cnf), and a phone-specific
configuration file containing settings applicable only to that phone (SIP<MAC-
address>.cnf, where <MAC-address> is the MAC address of the phone).
2. Manual configuration of the phone using its screen interface and keypad buttons.
With a few exceptions (one of which will be noted in Section 5.3.2), most parameters can be
specified in the configuration file(s), and this is the preferred method for maintaining a large
number of phones. Parameters that are manually changed at the phone will revert back to the
values in the configuration file(s) when the phone is re-booted, unless the DHCP and TFTP
parameters have been manually changed. See Reference [3] for details on installing and
maintaining Cisco SIP telephones using configuration files. For the sample configuration, the IP
address of the phone and its TFTP server were manually entered at the phone. The remaining
configuration was done via the configuration files where possible.
