Trying to get the above working. Basically your meant to be able to integrate Unified Presence with UCCX so that Agents can chat to External advisors. To me it looks very simple. You just point UCCX to CUPS and it grabs the users.
It would appear not as it does not work. I can verifiy the connection to the CUPS but when you search for contacts you get the following error:
CDAUI2067 Search did not complete successfully, and only partial results are displayed. Contact technical support.
