This document describes the procedure to change the logo on Cisco IP Phone 7905G,7921G and 7912G.Using TFTP, you can change the graphic which appears on the LCD screen.
Before you can change the graphic on the phone, you must use a graphics program to create an image with the following attributes:
Width of 88 pixels.
Height of 27 pixels.
Saved as bitmap file with the extension .bmp. For example, mylogo.bmp.
In addition, you will need the bmp2logo.exe tool, which converts your bitmap image file to a .logo file that can be downloaded to the phone. This tool is bundled with the Cisco IP Phone software. You can also obtain it from the CCO website at the following URL. It is included with the SCCP Software Package Zip file.
To change the graphic that appears on a Cisco IP Phone, follow these steps:
Step 1:- Open a command window and type the following command:
bmp2logo imageID image.bmp image.logo
•imageID is a unique identifier for the new graphic. This identifier must be a number from 0 through 4294967296 and must be different than the identifier of the graphic that is currently on the phone.
•image is the base file name of the image that you previously created and saved with the graphics program.
Note:- The imageID of the image that comes with the phone is 1.
For example, if the image identifier is 10 and the base name of your image file is mylogo, type this command:
bmp2logo 10 mylogo.bmp mylogo.logo
Step 2:- Copy the image.logo file to the following directory in the TFTP server for the Cisco Unified Communications Manager:
where:<country> is the country of your locale installer (for example, Greece for Greek).
Note:- Be aware that the file name and subdirectory parameters are case sensitive. Be sure to use the forward slash "/" when you specify the subdirectory path.
Step 3:- Add the following line to the Cisco IP Phone profile file
•imageID is the same unique identifier that you specified in Step 1.
•TFTPServerID is the IP address of the TFTP server on which the image.logo file is stored. If the image.logo file is stored on the same TFTP server as the Cisco IP Phone configuration file, replace TFTPServerID with the numeral 0.
•image is the base file name of the image file.
For example, if the image identifier is 10, the converted file is stored on the same TFTP server as the Cisco IP Phone configuration file, and the base name of the converted image file is mylogo, add the following line to the configuration file:
Step 4:- Use the cfgfmt.exe tool to generate a binary profile file from the text file.
The cfgfmt.exe tool requires a parameter tag file named ptag.dat. This filespecifies the type and size of each parameter. It is recommended that you use the ptag.dat file provided by Cisco.The cfgfmt.exe tool and the ptag.dat are bundled with the Cisco IP Phone software. You can also obtain them from the CCO website.They are included with the SCCP Software
