title: Voice Call CLI, RPC, and agent tool mock-provider flow

scenario:
  id: voice-call-cli-rpc-agent-tool
  surface: voice-call-channel
  category: voice-call-channel.channel-setup-and-operations
  coverage:
    primary:
      - voice-call.cli-rpc-agent-tool
  objective: Verify the Voice Call CLI, Gateway RPC, and agent tool share one executable mock-provider runtime.
  successCriteria:
    - The CLI starts an outbound call through its Gateway RPC path.
    - The registered Gateway RPC starts an outbound call through the mock provider.
    - The registered agent tool starts an outbound call through the same runtime.
    - Runtime status reports all calls and cleanup stops the local webhook fixture.
