Example: Setting a Custom Logo Display
The following example shows the configuration for uploading a custom logo picture “logo.dob”, and then setting it to
display on the phone idle screen. The logo picture is customized and placed on the provisioning server
“192.168.10.25”.
Example
lcd_logo.url =http://192.168.10.25/logo.dob
phone_setting.lcd_logo.mode =2
After provisioning, the phone displays the custom logo screen and the idle screen alternately.
Call Display
By default, the phones present the contact information (including avatar and identity) when receiving an incoming
call, dialing an outgoing call or engaging in a call.
