What type of calls do users initiate when they use outbound functionality with 3CX?

When users utilize the outbound functionality with 3CX, they are initiating calls to external numbers. This capability allows users to reach contacts outside their organization, making it essential for business communications that extend beyond internal extensions. The 3CX system is designed to facilitate these external communications effectively, enabling businesses to connect with clients, customers, or partners easily.

In contrast, the other options focus on specific types of calls that do not represent the primary use of outbound functionality. For example, calling internal extensions only restricts communication to within the organization and does not leverage the capability that outbound dialing provides. While video calls and conference calls are features available within the 3CX system, they do not specifically describe the nature of outbound calls, which are aimed at external connectivity. Thus, the ability to dial external numbers is the fundamental advantage of using outbound functionality in 3CX.
