This may depend on whether these are setup as SIP or MGCP phones. If they are SIP, I found the following:
iki/index. php?page=A sterisk+ph one+ cisco+ 79xx
m/asterisk /logo.bmp"
http://www.voip-info.org/w
Logo Displayed on 79XX Screen
A non-Cisco logo can be displayed on the 79XX screen. Cisco's documentation suggests the logo be a Windows Bitmap form (*.BMP) with 256 colors and 90 x 56 pixels in size. Only two colors are displayed, black or white. The image must be saved in greyscale format. In GIMP it is Image->Mode->Greyscale. If the size of the logo is larger then this specification, the phone will rescale to fit (within reason). Microsoft Paint and many other applications can be used to create the logo image.
Once the image is created, place the *.BMP file on any web site available to you (suggest /asterisk/mylogo.bmp, where the /asterisk directory is not freely advertised).
Modify the SIPDefault.cnt file entry to point to the web site:
logo_url: "http://www.mywebserver.co
and reboot the Cisco phone.
Note: the smaller the logo file, the quicker it will load. Typcial logo files should be around 10k bytes.
Note: 7940/7960 phones actually display two colors at 2-bit depth, or four solid colors. For best results creating images/logos that don't dither and degrade, use #000000 (black) and #FFFFFF (white or clear on the LCD display), then #404040 (dark grey) and #808080 (light gray) as your alternate solid colors (or as the antialiasing colors for excellent results).
