Yealink SIP-T2xP/T1xP IP phones allow you to customize the logo displayed on the phone
LCD screen (The SIP-T20P IP phone only supports displaying the text logo). Ask the
distributor for the logo file, or you can customize a .dob logo file. Upload the logo file to
the root directory of the provisioning server and then specify the access URL in the
configuration file:
####################################################
## Configure the access URL of the Logo File ##
####################################################
#(SIP-T2xP/T1xP only, not applicable to T20P)
lcd_logo.url =
#lcd_logo.delete = =http://localhost/all
#Delete all custom logo files
lcd_logo.delete =
For example: enter ftp://192.168.1.100/ logo.dob in the lcd_logo.url = field. During
the auto provisioning process, the phone links to the provisioning server 192.168.1.100,
and downloads the logo file logo.dob.
The following table lists the logo file format for each phone model:

Upload the logo file to the root directory of the provisioning server. After provisioning,
the phone boots up, and you will then find that the customized logo displays on the
phone LCD screen.
