It is obviously not new, but I found it this week, I have tested it and find it suitable for dial testing.
What is the drawback?
1) The text on the buttons are in German so we need to make a short translation picture, but the readings are clear and understandable.
2) you need an RS232 port, (I have an adapter USB-RS232)
To the point: Here is the link:

Download the link, run the file, and it asks for the serial port, type the number of the port, and Enter (twice), Then adjust EP to at least 2 to not get resonant pulses, then just start measuring.
I have just used pin 9 and 7 and tested the pulse contacts, or complete telephone, and that works so well.
