On the client:

Make sure you do a clean install on a system that had no TSP before.

After install go to control panel > Phone and Modem Options > advanced> select CiscoTSP001.tsp, click configure.

Check the version, should be 5.1(0.18)

The user should be an end user in CallManager, make sure the passwordis correct.

Make sure the correct CTI manager IP address is present.

On the security tab I only provided the TFTP address. other configuration settings are default

On CCMadmin:

Check that the end user has one controlled device

the user is part of the standard cti enabled and CCM End Users groups

the primary extension has been configured correctly

On the device: enable "Allow Control of Device from CTI", put the correct "Owner User ID"

On the line: enable "Allow Control of Device from CTI"

After all of the above has been configured/verified:

restart the CTI Manager service

reboot the client machine (was necessary for me to get it to work)
