From Shahryar @ Cisco in a recent "Ask the Expert" event;
This question comes up quite frequently. The differences are in the composition of the products in the two suites, how support is delivered, SKUs and cost and name branding. The Smart CallConnector products are for the UC500 and supported by S-TAC. The Unified CallConnector products are for the CUCME and supported by TAC. But the common products (such as Operator, Server or Advanced Client) are identical in functionality, only the name is different.
The Smart CallConnector (SCC) suite is comprised of:
Smart CallConnector Operator -- designed for the main answering position of small businesses
Smart CallConnector Advanced Client -- providing CTI and Outlook integration, Presence, IM, Directories etc
Smart CallConnector Server (required for Advanced Client and for two or more operators)
Smart CallConnector Toolbar -- toolbars in Outlook and IE providing basic call popup notification and call handling
The Unified CallConnector suite is comprised of:
Unified CallConnector Operator -- (same functionality as the SCC Operator)
Unified CallConnector Advanced Client -- (same functionality as the SCC Advanced Client)
Smart CallConnector Server (same as SCC Server)
Unified CallConnector Client -- provides standalone call handling, integration with Outlook, click to dial, directories and call logs.
