How to Customize the Default Configuration File
Note
For a complete alphabetical list of configurable parameters, see
Appendix D, “SIP IP Phone
Parameters.”
Prerequisites
•
If you have an existing system from a release earlier than Release 7.x, upgrade your system firmware
as described in the
“How to Upgrade Your Cisco SIP IP Phone Firmware Image and Reboot
Remotely” section on page 4-3
before proceeding.
Procedure
Step 1
Obtain the default configuration file as follows:
a.
Go to the Cisco.com SIP IP 7940/7960 phone software-download site at
http://www.cisco.com/cgi-bin/tablebuild.pl/sip-ip-phone7960
.
b.
Download the SIPDefault.cnf file to the root directory of your TFTP server or to a subdirectory in
which all phone-specific configuration files are stored.
Step 2
Using an ASCII text editor such as vi, open the file.
Step 3
Modify the following required parameters:
•
image_version—Specifies the firmware version that the Cisco SIP IP phone should run. Enter the
name of the image version (as it is released by Cisco). Do not enter the extension.
Note
You cannot change the image version by changing the filename because the version is also
built into the file header. Trying to change the image version by changing the filename
causes the firmware to fail when it compares the version in the header against the filename.
•
proxy1_address—IP address of the SIP proxy server that is used by the phones. Enter the address in
IP dotted-decimal notation or use the FQDN.
•
tftp_cfg_dir—Specifies the path to the TFTP subdirectory in which phone-specific configuration
files are stored. Required only if the phone-specific configuration files are located in a subdirectory.
Step 4
Modify additional parameters as needed.
Step 5
Save the file to the root directory of your TFTP server or to a subdirectory in which all phone-specific
configuration files are stored.
