How to enable Message Carbon feature - XEP-0280, in Openfire Server Level

Is there any property controls in server level for Message Carbon feature(XEP-0280) in Server Level?

Thanks

This feature is always enabled in Openfire. It cannot be switched off, as far as I know.

Thanks for your quick reply. I have been facing issue in carbon copy even after adding required element changes in iOS client “enable xmlns='urn:xmpp:carbons:2”. Does route.all-resources property needs to set for this feature to enable ? What would be the difference between carbon copy and routing ?

Appreciate your response.

Thanks
