Examples
Choose a queue-backed architecture for bursty inbound calls
For a campaign that creates short spikes, keep the public number attached to a stable routing layer and place CRM enrichment behind an asynchronous queue. Start with a preview agent that records only synthetic test calls, set a clear timeout for the enrichment request, and configure a human-transfer fallback. Measure latency and transfer rate during the canary before selecting the variant for production traffic.
