How does enterprise trunking work in Avaya Aura?

Enterprise trunking in Avaya Aura specifically facilitates communication between different sites within an organization without incurring telephony charges. This means that calls made between branch offices or remote locations using enterprise trunking do not utilize the public switched telephone network (PSTN), which typically incurs costs for long-distance calls. Instead, these calls are routed over a secure and efficient internal network, optimizing communication costs for the enterprise.

By leveraging enterprise trunking, businesses can enhance their internal communications while minimizing expenses, making it a vital component for organizations that need to maintain seamless connectivity between multiple locations. This capability is crucial for large enterprises that operate across various geographical areas, allowing them to manage their costs effectively while ensuring robust communications.

In contrast, the other options provided do not align with the primary function of enterprise trunking. Connecting external telephony providers pertains to how an organization integrates with the PSTN but does not capture the essence of trunking for internal site communication. Local area network management focuses on network infrastructure rather than voice communication efficiencies facilitated by trunking, and hardware sourcing is unrelated to the functionalities offered by enterprise trunking in the Avaya Aura framework.
