Hi there,
Part of the problem here may be related to the EoL (End of Life) for
CUCM 6.1
End-of-Sale and End-of-Life Announcement for the Cisco Unified Communications Manager Version 6.1
End of New Service Attachment Date: HW, App. SW | For equipment and software that is not covered by a service-and-support contract, this is the last date to order a new service-and-support contract or add the equipment and/or software to an existing service-and-support contract. | September 3, 2011 |

You don't mention the exact MCS-7816 model but many have been EoL as well
Here is an example;

I'm no expert on smartnet but I believe you'll find the CUC stuff under "ESW" support.
Cheers!
