To be able to add images on devices, you must already have a TFTP-Server and of course the necessary .xml configuration files.
Every cisco telephone set has it’s own demands. The image format must be on .PNG with specific dimensions
Telephone set | Image dimensions (pixels) | Thumbnail dimensions(pixels) | TFTP Folder |
7906/7911 | 95 X 34 | 23 X 8 | /Desktops/95x34x1 |
7941/7961/7942/7962 | 320 X 196 | 80 X 49 | /Desktops/320x196x4 |
7945/7965/7975 | 320 X 212 | 80 X 53 | /Desktops/320x212x16 |
7970/7971 | 320 X 212 | 80 X 53 | /Desktops/320x212x12 |
Every image folder on the TFTP-Server must contail the file List.xml (e.g. /Desktops/95x34x1/List.xml) with the following contents :
<CiscoIPPhoneImageList> <ImageItem Image="TFTP:Desktops/320x212x12/TN-CampusNight.png" URL="TFTP:Desktops/320x212x12/CampusNight.png"/> </CiscoIPPhoneImageList>
For every custom image we add two lines among CiscoIPPhoneImageList tags. First goes the thumbnail (after Image=) and then the complete image (after URL=).
If everythig go as expected in menu User Preferences > Background Images you will find your custom images.
