During the auto provisioning process, the phone connects to the provisioning server
“192.168.1.100”, and downloads the language file “lang+English.txt”.
Available languages may vary between different firmware versions.
Do not rename the language file.
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 not applicable to the SIP-T46G and SIP-T42G IP phones. The logo file format must
be .dob, and the resolution of the SIP-T41P IP phone 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-T41P IP phone 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-T41P IP phone 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 53.
Yealink SIP-T46G IP phones allow you to customize the wallpaper displayed on the LCD
screen. Wallpaper feature is not applicable to the SIP-T42G/T41P IP phones.
