Screen saver interrupted by Shared Parking change

[complex1]

Hi,

I don't think you can disable this.

As you can read in the User Guide on page 43:

"The screen saver will automatically start when the IP phone is idle for the preset waiting time.
The screen saver is used to blank the screen or fill it with moving images or patterns.

The screen saver will be stopped if one of the following phone events occurs:

Press any key.
Pick up/hang up the handset.
There is an incoming call.
A new prompt (e.g., missed call, new voice mail or forwarded call).
The status of BLF key changes."

Hope this helps.
