The Holo call is exactly as you described it, someone in your party will start the conversation for the particular quest that if you have completed as well you can join in via Holo Call, if the person starting the conversation waits long enough for you too stand still and click the button for joining the conversation. It takes a second to load but works great if you arent ready to go turn in the quest and still wanna join in the conversation for the social points.
