The ability to prevent unwanted audio and video communications through the Messenger application is a user-controlled function. This action effectively silences incoming voice and video connection attempts from specific individuals. An instance of its application would be in preventing a persistent contact from initiating calls without prior agreement.
Controlling communication flow provides a significant degree of personal autonomy. It allows users to manage their availability and minimizes disruptions caused by unsolicited contact. Historically, methods for filtering communications were limited, leading to potential disturbances; current features address this by providing precise control over interaction.
