Technically, this isn't a problem. It's a feature that is not implemented. What I believe you are looking for is message carbons, which is described in the XEP-280 specification http://xmpp.org/extensions/xep-0280.html
This specification is still in the experimental stage of the standards process, and is not implemented in Cisco IM&P or Jabber. When it is implemented in IM & Presence, it will be implemented in the Cisco Jabber clients and SDK, too.
