screensaver.upload_url
Description:
Configures the access URL of the custom screen saver image.
Example:
screensaver.upload_url = http://192.168.10.25/Screencapture.jpg
During the auto provisioning process, the IP phone connects to the HTTP provisioning
server ―192.168.10.25‖, and downloads the screen saver image
―Screencapture.jpg‖.
If you want to download multiple screen saver images to the phone simultaneously,
you can configure as following:
screensaver.upload_url = http://192.168.10.25/Screencapture.jpg
screensaver.upload_url = http://192.168.10.25/Screensaver.jpg
Note: It works only if the value of the parameter ―screensaver.type‖ is set to 1
(Upload Picture). It is only applicable to SIP VP-T49G, SIP-T48G, SIP-T46G and SIP-T29G
IP phones.
