Customizing Wallpaper - Yealink SIP-T4X Provisioning Manual

Getting Started
Logo customization allows unifying the IP phone appearance or displaying a custom
image on the idle screen such as a company logo, instead of the default system logo.
Logo is applicable to SIP-T42G and SIP-T41P IP phones only. The logo file format must
be .dob, and the resolution of the SIP-T42G/T41P IP phones is 192*64 graphic.
Ask the distributor or Yealink FAE for the logo file, or you can customize a *.dob logo file.
Upload the logo file to the provisioning server and then specify the access URL in the
configuration file:
####################################################
## Configure the access URL of the Logo File ##
####################################################
#(For SIP-T42G and SIP-T41P IP phones only)
lcd_logo.url =
#lcd_logo.delete = =http://localhost/all
#Delete all custom logo files
lcd_logo.delete =
For example, enter "tftp://192.168.1.100/logo.dob" in the "lcd_logo.url =" field. During
the auto provisioning process, the phone connects to the provisioning server
"192.168.1.100", and downloads the logo file "logo.dob".
To use the custom logo, you also need to configure the following parameter:
#Configure the logo mode (For SIP-T42G and SIP-T41P IP phones only).
#0-Disabled, 1-System logo (default), 2-Custom logo
phone_setting.lcd_logo.mode = 2
After auto provisioning, you will find that the custom logo appears on the LCD screen.
For more information on customizing a logo file, refer to Customizing a Logo File Using
PictureExDemo on page 55.
