If you open a case, yes we dont support you
Why dont you use the Click to call Widget (It has an outlook toolbar)
or if you have CUPS use the Addon for CUPC
If you still wanna go for the TSP integration
I normally check TSP logs which are pretty easy to read
or install the softphone and test
You can upload TSP logs, in the forum plenty of posts for this you may wanna take a look
