You need to configure CiscoTSP first after install.
On CUCM side, you need o create a user for TSP client, and add the user into "Standard CTI Enabled" user group. Then add the deivce you want to control into the user's controlled device list.
You need to configure CiscoTSP UI to provide user and CTIManager you want to connect. please refer to
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/tapi_dev/6_0_1/tpdevch2.html where you can find general idea how to configure TSP UI. However, the link does not tell you how to configure security tab, but you can ignore that for now since you won't need it unless you want to use TLS.
Now you can start your TAPI app and your TAPI client should be able to connect to CTIManager you configured.
