With the help of ephone.exe you can record sessions and provide them for analysis if necessary. 

Please run the test on the computer on which the TSP of the telephone system or telephone is installed!

Limit the causes of errors: TSP 

If one of the above steps is not possible, for example:

  • You do not see any TAPI lines
  • You cannot open the TAPI line, i.e. the button Start Session cannot be clicked
  • You get an error message in the footer of ePhone.exe like "Operation Unavailable", "Invalid Line State
  • The ePhone.exe does not react to "Make Call" at all

then the error is usually found at the TSP. Please contact the manufacturer of the TSP directly.
