Hello triangular,
Quick view forms can be set up by configuring a Lookup field and the type of Entity (in your case specifically, it would be User).
Unfortunately the fields you are looking to use are both of type "Party List", which is essentially saying this fields can be filled in by one (or more users). This is the reason these fields aren't displayed in your options, in the grid.
Not being sure of the entire purpose here, you could for example add a new Lookup field for Users and add it to the Phone Call form. This way you could link it to your Quick View form and display the information.
Hope that was helpful,
