You can capture the screen display of the IP phone using the action URI. The phones can handle an HTTP or HTTPS GET request. The URI format is http(s)://<phoneIPAddress>/screencapture. The captured picture is saved as a BMP or JPEG file.
You can also use the URI “http(s)://<phoneIPAddress>/screencapture/download” to capture the screen display first, and then download the image (which is saved as a JPG file and named with the phone model and the capture time) to the local system
