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.
