Example: Capturing the Current Screen of the Phone
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.
Note
: Yealink phones also support capturing the screen display using the old URI “http://<-
phoneIPAddress>/servlet?command=screenshot”.
Before capturing the phone’s current screen, ensure that the IP address of the computer is included in the trusted IP
address for Action URI on the phone. When you capture the screen display, the phone may prompt you to enter the
user name and password of the administrator if the web browser does not remember the user name and password
for web user interface login.
Procedure
1. Enter request URI (for example, http://10.2.20.252/screencapture) in the browser's address bar and press the
Enter key on the keyboard.
2. Do one of the following:

If it is the first time you capture the phone’s current screen using the computer, the browser will display
“Remote control forbidden”, and the phone screen will prompt the message “Allow remote control?”.
