Hello,
You have an obsolete URL (www.cisco.com/univercd/ ...) that used to be called CCO and is now retired. You may have bookmarked this obsolete URL; You'll want to change that bookmark now.
Here's the URL on Cisco.com that is the Doc Roadmap page that lists all versions of the Cisco Unified Communications Manager (CUCM) docs, including the 7.1 and 7.0 versions: http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_documentation_roadmaps_list.html
This is the listing page for CUCM (CallManager) where you can see a listing of types of tech docs for CallManager: http://www.cisco.com/en/US/products/sw/voicesw/ps556/tsd_products_support_series_home.html
In the future, you can search in Cisco.com by typing in a shortcut name of "CallManager 7.1" or whichever "CallManager 7.x.x" docs to get a listing of CUCM 7.x docs.
As an alternative, instead of searching on Cisco.com, we have a wonderful /go/techdocs URL that takes you in a flash to the Product/Technology Support page where you can select your router or technology area to drill down to the technical documentation page listing different types of tech docs. The /go/techdocs URL is at: http://www.cisco.com/go/techdocs
Appreciate your post and let us know if this helps.
