What setting must be defined on a work stream to use Operating Hours on an SMS Phone Number channel?

To use Operating Hours on an SMS Phone Number channel, it is essential to define the setting for allowing automated messages. This setting directly impacts how the channel operates during the defined operating hours. When operating hours are established for a work stream, the system can control when automated messages are sent to customers, aligning with the business's operational schedule and ensuring communication occurs only during designated hours.

Establishing this setting helps in providing a responsive customer service experience while respecting the boundaries of operating hours, which can lead to improved customer satisfaction. During these hours, automated responses can be programmed to engage with customers, ensuring they receive timely acknowledgments and assistance based on availability.

Other settings like autoclose after inactivity, capacity, and work distribution mode pertain to different aspects of managing interactions and resources within the work stream but do not directly relate to the function of using operating hours with an SMS Phone Number channel.
