Hello, when we do an end user upgrade from the Cisco TSP 4.1 to the Cisco Unified Connnections Manger TSP 6.1, the upgrade uninstalls the CiscoTSP from 'phone and modem options'. You can not add the TSP in there either. I have uninstalled everything, deleted the cisco folder, deleted registry entries, and I am still unable to get the CiscoTSP working with version 6.1. Any ideas? Thanks in advance.
