What feature allows users to set up multiple lines on a single device in Webex Calling?

The feature that allows users to set up multiple lines on a single device in Webex Calling is found in line keys. Line keys provide a way to assign multiple telephone numbers or lines to a single phone. This enables users to manage different lines simultaneously from one device, facilitating efficient call management and enhancing user productivity.

Each line key corresponds to a specific line or number, making it easy to switch between them. This is particularly advantageous for users who may need to handle calls for various roles, clients, or departments without needing multiple physical devices. The ability to visually identify lines through the line keys on the device enhances user experience and helps in quickly responding to incoming calls or managing active conversations.

While multi-line configuration options also relate to setting up multiple lines, it is the line keys that directly enable this functionality on a physical device. Group calling functionality and call forwarding settings serve different purposes and do not specifically address the ability to have multiple lines on a single device.
