Using the standard HTML Player
Interviewers can conduct telephone interviews either using a mouse to click buttons and position the cursor on the screen or by pressing keys or combinations of keys on their keyboards.
The default is for the Phone Participants activity to expect keyboard input (it uses the Keyboard player).
If you want interviewers to use their mouse, change the value of the HTML_PLAYER key in the Phone Participants Web.config file to this:
<add key="HTML_PLAYER" value="HTMLPlayer" />
