Which of the following statements about "Outbound Rules" is true?

The statement regarding "Outbound Rules" that is true is that calls from extensions can indeed use multiple extension ranges. Outbound rules are defined to control how calls are handled based on specific conditions, including the originating extension. With the flexibility of multiple extension ranges, administrators can easily configure rules that allow a certain set of extensions to share the same outbound dialing criteria, which enhances efficiency and organization within a VoIP system like 3CX.

The ability to define multiple ranges means that you can accommodate various extensions that may belong to different departments or teams, ensuring that the calls can be routed properly without needing individual rules for each extension. This simplifies the management of outbound calls and allows for scalability as more extensions are added to the system.

Regarding the other options, the criteria-based approach to routing calls ensures that rules are processed based on defined parameters rather than a random selection, highlighting the structured nature of how outbound calls are managed. Additionally, while defining extension ranges, the system does allow for comma-separated values, enabling greater flexibility in specifying ranges or individual extensions. Thus, the concept of using multiple extension ranges for outbound rules supports a more streamlined and effective communication strategy in a business environment.
