Best bet is to either try some of the other HF frequencies listed on the back flight progress charts or if that fails 123.45 (the "chat frequency") and ask nicely for a relay from another aircraft still in touch with your station. As a last resort you could give 121.5 (guard frequency) and request a relay.
Hope that answers the question.
