Note
Customizing a Logo Template File
The common picture format can be *.bmp. Yealink IP phones only support the *.dob format
logo files. Yealink provides PictureExDemo tool to convert *.bmp format to *.dob format. You
can ask the distributor or Yealink FAE for the PictureExDemo tool.
Before uploading your custom logo to IP phones, ensure your logo file is correctly formatted.
