What is the Sequential distribution pattern used for?

• A. To equally distribute calls across all trunks
• B. To route calls to the next available trunk sequentially
• C. To prioritize calls to the most frequently used trunk
• D. To load share calls randomly among trunks

Answer: (B)

The Sequential distribution pattern is designed to route calls to the next available trunk in an orderly manner. When using this distribution method, the system attempts to send calls through trunks in a specific sequence, ensuring that each trunk gets a fair opportunity to handle calls one after the other. This method can be particularly useful in scenarios where you want to maintain an organized flow of calls, avoiding congestion on any single trunk and ensuring that all available resources are utilized efficiently over time.

This approach contrasts with other distribution patterns. For instance, an equal distribution would send calls to all trunks simultaneously, while prioritizing trunks would focus on one trunk based on usage metrics. Random load sharing differs significantly as it introduces unpredictability in trunk selection. Hence, the Sequential distribution pattern's systematic approach is effective for managing calls while promoting equal opportunity for trunk utilization.
