Someone who doesn't like making phone calls or picking up calls is often referred to as "phone-shy" or "phone-averse." These terms describe individuals who feel uncomfortable, anxious, or avoidant when it comes to using the phone for communication. Phone shyness can be related to various factors, such as social anxiety, preference for other forms of communication (e.g., texting or messaging), or a dislike of the direct and immediate nature of phone conversations.
