Some models in the series come with the capability to connect to separate handsets, allowing for easy expansion of home or office communication systems. This scalability means that users can add additional handsets without the need for extra phone lines, facilitating seamless communication throughout larger spaces.
Another key feature is the caller ID and call waiting functionality, which helps users to screen calls effectively. Users can easily see who is calling before answering, thus enhancing their control over incoming communications.
