Yealink W73P (W70P + W73H) Remote control

[zebrik]

So, I've finally found the Yealink SIP IP Phones XML Browser Developer's Guide_V81_72 which is much more detailed than the regular doc. I've found the Execute object description there.

Another problem - I can't get /servlet code running. The documentation to w70b states I can run the PHP code to run pushXML, but it never lets me in -

Code:

curl --location --request POST 'https://192.168.69.80/servlet?push=xml' \
--header 'Content-Type: text/xml' \
--header 'Referer: 192.168.69.143' \
--data-raw '<?xml version="1.0" encoding="ISO-8859-1"?>
<YealinkIPPhoneTextScreen Beep="yes">
<Title>Push test</Title>
<Text>This is a test for pushing text to a phone.</Text>
</YealinkIPPhoneTextScreen>'

and I get 403 - User level forbidden

Playing with authorization - basic or digest doesn't help.
