Signal, a popular encrypted messaging app, has significantly enhanced its group call capabilities, introducing call links that allow users to join a call without requiring a group chat. This feature aligns Signal with other videoconferencing software and enhances its competitiveness. The new call links are reusable, making them suitable for recurring work meetings or family chats. In addition to call links, Signal has implemented features within its calls, including a “raise hand” button and emoji reactions. These enhancements offer greater convenience and user engagement.
