Remote control of a snom desktop phone

Reading through this web page, I would find some commands of value to me:
https://service.snom.com/display/wiki/Remote+phone+c...

Sadly, I cannot get anyone of those suggested commands to work for me, like:
http://tramway:[email protected]/command.htm?DND
Any suggestions what to change in the syntax for it to work?

What I would really like is to be able to do is to kill off forwarding on a remote desktop phone. Is that possible?

I would just like to say that the URL http://tramway:[email protected] does actually log me into the desktop phone.

“Note: If you have changed HTTP user name, HTTP password and the Administrator Password from the default value, hidden tags have to be disabled in order to use the remote control feature.”

Have you done that?

In reply to a post by Pheasant:

“Note: If you have changed HTTP user name, HTTP password and the Administrator Password from the default value, hidden tags have to be disabled in order to use the remote control feature.”

Have you done that?

You don't have any choice in the matter!
I can confirm the Userid, password and administration password are of my choosing.

Hidden tags are disabled.

I can only access the GUI of the phone using HTTP though.

So none of the remote commands are working? Did you get any acknowledgment on your browser or error message in particular? Have you tried sending the commands via a different browser or machine?
