"Anything I missed?" is better than "any questions?" but even better would be "what have I missed?" because it makes you question open and can't easily be answered with yes or no and therefore requires more engagement. I usually ask "what have I missed?" or, more often, "which questions do you have?" -- both require more than a silent treatment as an answer and the "which" question in particular is very open and invitational.
