You may need to wait a while in-game. It is a well-reported issue that such plot dialogues can take even up to a couple of minutes of static before they start.

incoming static with dr. Feynman, Dal Busta, and human from finish of Split plot (from def station which would became argon one)
can stuck forever (i waited 40 minutes)
and can be work around with standup from pilot seat (no video, but audio and subtitles would play immediately)
other work around (if no pilot seat around): call any of your personnel ..., but this would lead to loss of all information which you should receive by plot,
but mission will be updated,
i asked to give option to disable all video calls (they do introduce problems some times independent of this bug), only caller and his ship name should be visible somewhere (not blocking other information on right display), otherwise it should be audio only call, but probably it was lost somewhere....

it does happens with older/cheaper video cards(mine have 2gb ram).
(you can try to set lowest graphical settings as workaround, but that would not work for me, as i do play on minimal settings already)
