The Chinese are not stupid people. Donald Trump has been a public figure for 40 years now. By now, the Chinese intelligence and diplomats would have compiled a huge dossier on Trump. There has been countless editorials and articles about Donald Trump ignorance, anger issues, and unpredictability.

What likely is going to happen is the Chinese government will make a few statements and mild complaints. They know that Donald Trump has a habit of fighting and getting angry if he feels insulted. They will regard him as a childish buffoon that has to be handle carefully. It's likely Trump didn't know that he wasn't to talk directly to the Taiwanese government.
