How to ask client for his version (XEP-0092)?

Hi,

I am reading there is a XEP that server asks the client for his version and other client information:

http://xmpp.org/extensions/xep-0092.html

However, when I debug the packet transfer with Smack, Openfire does not send such an IQ to the client.

The protocol support says, it is supported:

How can I make Openfire send the IQ and where does it store the reply (if at all)? Or what would Openfire do with a reply?

Thanks!
