Welcome to your interview.
The question is on your right: Service Desk Telephony Systems. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What telephony system do you use in service desks, and how would you design it to support incident and request handling?
