My mobile phone can't answer the phone, and the other party's mobile phone shows that I am on the phone, and then the other party's mobile phone will receive a short message saying that I will call later in the meeting. Why? If you weren't really on the phone, then you might have blocked the other party. When you set to block a mobile phone number, the other party keeps reminding you that the number is busy, and you don't know what the result of the short message is. Please check whether the other party's number is blocked on your mobile phone. If not, please call customer service. They should be able to help you solve this problem. I hope they can help you.
