As you answer the calls, you will interact and talk with all kind of characters. Each character has their own personalities, backgrounds, and quirks. Once a character talks they present their request and discuss with you, or some unusual event might happen, you will never be in danger. Once a call ends the phone starts ringing again immediately. Calls can be unusual, they can have wild requests and behavior, they can be real, fictional, historical figures, media, etc.. with requests of any kind.
