T42G - Action URL and XML browser

[MRS]

Hello,

I am trying to display a server status via action url and xml browser. The phone is sending a request via action url (Registered, Unregistered ...) to the server and a xml content is in the response, which should be executed on the phone.

The XML-Content is working via Line Key - XML Browser, but it doesn't work via action url reqeust. Why it doesn't work?

XML-Content:
<?xml version="1.0" encoding="ISO-8859-1"?>
<YealinkIPPhoneExecute Beep="yes">
<ExecuteItem URI="Led:LINE2_GREEN=on"/>
</YealinkIPPhoneExecute>
