Chrais,
Both of your questions are pretty easy.
1. Reporting - there are 2 flavors in IPCC Express. Real Time Reports and Historical Reports. Both come with any license of the product, there are 3 license levels, Standard, Enhanced, and Premium.
To access Historical reports ( which is more valuable for just about any customer ) you have to log into the appadmin page ( http://ipofserver/appadmin ) and click on tools, plug-ins, and download and install the Historical Reports clients on 1 ( note I said 1 ) windows xp or windows 2000 machine. If your customer wishes to run more than 1 instance of historical reports at a time Cisco recommends that the users purchase high availability option, meaning they have more than 1 database and engine servers.
2. CAD - CAD comes with both Enhanced and Premium license levels. To get CAD you have to go to the app admin page ( see above post ) and goto tools, plug-ins, and Cisco Desktop Software, and install the Cisco Agent Desktop. You will need to configure users and associate users to phones the same as in enterprise product in order for the users to be able to log in.
The reporting is horrible compared to enterprise level reporting, I dought your customer is going to be very happy with the reports, no one I know of is. Also, a big stink going around right now, is that report data doesn't migrate between versions when you do an upgrade. Just another thing to consider...
Cheers,
Alex
