I'm using the Cisco TSP x64 driver. It worked without any problems on Windows 8.1
After upgrading my machine to Windows 10 Enterprise it doesn't work any more. It seems that the behavior for loading the configuration data changed in Win10:
If I access the configuration with the configuration app that ships with the TSP, I'm able to see all configuration entries with their correct values. This can be verified by examining the registry. Everything is there as expected.
When I access the configuration via the settings app (Telephone & Modem-> Advanced) the configuration dialog is shown but apparently no configuration data has been loaded. All fields are empty. Entering some data and dismissing the dialog doesn't help, the data is gone when I reopen the dialog.
I haven't found any special information regarding TAPI on Windows 10. Is this a bug?
This is a showstopper for Windows 10 in our environment since we use the TSP to control our telephone system from the desktop.
Any help would be greatly appreciated.
Thanks in advance
Uwe
