Chapter 6 Configuring the Cisco IP Phone Models 7905G and 7912G Using a TFTP Server

Creating or Updating a Profile

configure parameters in the unique profile that are specific to a phone. For more information about the Include parameter, see the “Profile Parameters” section on page 8-26.

Procedure

Step 1 Use a text editor to open the sipexample.txt file or to open another existing text profile.

Step 2 Edit or enter parameter:value pairs in the profile as needed.

For an explanation of parameters that you can include in a profile, see Chapter 8, “Profile and Web Page Parameters and Defaults.”

Note If you use the Include parameter, Cisco recommends that it be the first parameter in a text profile file. Any parameters in a text profile that come before an include statement will be overwritten with values from the same parameters, if they exist, in a common profile.

Step 3 Save the file and name it as follows, where each xx is the two-digit lowercase hexadecimal representation of each integer in the phone’s MAC address. A file name must contain exactly 14 characters.

•File name for the Cisco IP Phone 7905G: ldxxxxxxxxxxxx.txt

•File name for the Cisco IP Phone 7912G: gkxxxxxxxxxxxx.txt

You can determine the MAC address of a phone from the MAC Address parameter in the Network Configuration menu or the Device Information area in the phone’s web page.

Step 4 Open a command window and type the following command to generate the binary profile file from the text file:

cfgfmt [-eRC4Password][-tpTagFile]input-text-file output-binary-file

where:

•RC4Password is the optional RC4 key, up to eight alphanumeric characters, to encrypt the binary profile that is generated by the cfgfmt tool. For more information, see the “Using Encryption” section on page 6-15.
