Call screening is a feature that allows users to identify and manage incoming calls before answering them. This can involve displaying the caller's name and number, or even playing a pre-recorded message that prompts the caller to state their name or purpose. This helps users decide whether to answer, ignore, or send the call to voicemail. Many smartphones and landline services offer call screening options, enhancing user control over their phone interactions. By using caller ID and voicemail features, individuals can reduce unwanted calls, such as those from telemarketers or unknown numbers, leading to a more efficient communication experience.
