Places an outbound call to a contact, and then initiates the flow. It performs the actions in the flow that's specified (in ContactFlowId).

Agents do not initiate the outbound API, which means that they do not dial the contact. If the flow places an outbound call to a contact, and then puts the contact in queue, the call is then routed to the agent, like any other inbound case.

There is a 60-second dialing timeout for this operation. If the call is not connected after 60 seconds, it fails.

UK numbers with a 447 prefix are not allowed by default. Before you can dial these UK mobile numbers, you must submit a service quota increase request. For more information, see Amazon Connect Service Quotas in the Amazon Connect Administrator Guide.

Campaign calls are not allowed by default. Before you can make a call with TrafficType = CAMPAIGN, you must submit a service quota increase request to the quota Amazon Connect campaigns.
