  title: Twilio Create a Call Queue and Confirm It
  summary: Create a voice call queue with a size limit, then fetch it back to confirm its configuration.
  description: >-
    A call routing setup pattern. The workflow creates a new call queue with a
    friendly name and a maximum size, then fetches the queue resource back by its
    SID to confirm the configuration and read the current size. This is the
    standard chain for provisioning a queue that inbound calls can be enqueued
    into. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
