Configuring The Push Xml Server - Yealink SIP-T48G User Manual

The screenshot of the IP phone user interface for reference is shown as below:
The phone can request an XML object via HTTP GET, or an object can be pushed to the
phone via a POST. The phone parses this object immediately upon receipt and
displays the information on the screen. You can ask the distributor or Yealink FAE for
php source code or obtain php source code online:
http://support.yealink.com/documentFront/forwardToDocumentFrontDisplayPage.
The HTTP POST packet must contain an "xml=" line in the message body. XML data is
located after the equals sign in the message. HTML forms that post objects to the
phone must use a field named "xml" to send data. The applications that construct
HTTP packets must also specify this line.
To accept a pushed message, the "PushXML_ServerIP" parameter on the phone must
be configured as the IP address of the push XML server. For more information, refer to
