I'm using CUCM ver. 6.1.1 and TSP ver. 6.1 but I'm not able to get click to dial working with Windows XP. Vista works but not XP which is a little surprising to me. Should I try an older TSP version?
Windows XP is not a tested/supported platform for the TSP 6.1. Click to Dial is supported via Cisco Personal Assistant Server. Right now XP is not supported.
