What role do trunks play in the 3CX communication system?

Trunks in the 3CX communication system serve a crucial function by connecting the internal PBX system to external telephone networks. This connection allows users to make and receive calls to and from traditional phone lines, mobile networks, and VoIP services.

When a trunk is configured, it acts as the gateway through which voice and data traffic can flow, bridging your internal communication systems with the outside world. This is particularly important for businesses that rely on external communication, enabling seamless interaction with customers and clients. VoIP trunks, for example, utilize internet connectivity to facilitate these calls, providing cost-effective solutions for handling a high volume of external calls.

Understanding the role of trunks is essential for managing and optimizing a 3CX system, as it directly impacts how efficiently your organization can communicate with external parties.
