XML browser simply means that the SIP phones’ LCD screen display can be managed
by external applications.
This guide shows you how to use XML API to control the LCD screen display of Yealink
IP phones as well as its configuration. The XML API is intended to provide you with
flexibility in developing applications on the phones while tightly integrating into the
phone’s telephony capabilities and functions.

administrators, or network engineers with information for developing and deploying
customized client services to Yealink IP phones using the XML browser feature.
