You can customize a *.dob logo file, upload the logo file to the provisioning server and
then specify the access URL in configuration files:
####################################################
##
####################################################
#Specify the access URL of the custom Logo File.
lcd_logo.url =
For example, enter "tftp://192.168.1.100/logo.dob" in the "lcd_logo.url =" field. During
the auto provisioning process, the IP 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.
#0-Off, 1-System logo, 2-Custom logo
phone_setting.lcd_logo.mode = 2
After auto provisioning, you will find that the custom logo or text logo appears on the
LCD screen.
#Delete all custom logo files.
lcd_logo.delete = http://localhost/all
