This feature enables members of a particular group or department to answer calls that are ringing on another member's phone within the same group. When a call is received, any member of the group can pick up the call by dialing a specific code or pressing a pre-assigned button on their phone. This feature is commonly used in businesses and organizations to improve communication and collaboration among team members.
