If I need that, I send a message like "hey, you got time for a quick call to talk about x?". It's normally better to just figure out what you want to say and send it as a dm though, a call is a heavyweight escalation for rare and complex issues. It's also normally not a "question" per se, more a request for collaborative design or debugging.
