If the team leader asks if you didn't answer the phone on purpose, how can you ignore him?

Don't get angry if you know that the other party is deliberately not answering the phone. You can reply to him like this: I'm sorry, I didn't know you were really busy just now, but I do have something urgent to find you, otherwise I wouldn't call at this time, just anxious and want to solve the problem as soon as possible. Listen, I'll contact you when you are free.

Often when you calm down, he will feel a little guilty for not answering the phone. If you get angry with him again, you'll both get angry and you won't solve the problem.
