The directory is stored in an SQL Database on the CUAC Server, nothing is stored or cached locally on the CUAC Client PC and the database is queried every time a search is run.
The slowness could caused by a few things, you could ensure you priorotize the traffic between the CUAC Client and Server, specificly port 1433 for SQL.
Are you using the free version of SQL Express whici installed with CUAC? The recommendations are to use SQL Standard or Enterprise is you have over 10,000 contact entries for performance reasons. SQL Express can only use a single CPU so it could be a SQL performance issue.
Have you tried running the client on the server for testing purposes to see how the response is? This would help you determine if it is network related or performance of SQL itself.
i've suggested to my SI to install the app on the cueac server as you suggested as I would also do this but the SI does seem to think of this logic. I will ask them about the SQL question, I also think maybe they have not spec. it correctly for the 80k+ user
One of my customer is planing to use CISCO Unified Attandant Console Business Edition for the Operator ;
He has BE6000 with 300 users ; I have gone through the Server Software requirements for the Attandant Console Application ; It is mentioned that CUAC Business edition is works with Windows 2008 server OS with 32bit and 64 bit ;
But currenty windows 2008 server OS license is not orderable and we are forced to use Windows 2012 64 bit OS ;
Could you please let me know whether CUAC-BE is compatible with Windows 2012 , 64 bit Server OS.or not ;
I tried to install the CUAC BE application on Windows 2012 64bit OS but it gives me an error and i am not able to install the CUAC-BE application on this .
