Call contacts who don't reply to a WhatsApp campaign

WhatsApp campaigns for text agents have a Call fallback section. Turn on "Call unanswered contacts", pick a voice agent and set how long to wait before calling, from 1 to 24 hours. Each contact who hasn't replied to the template by then gets one automated call, within the campaign's schedule windows and before its end date. You can also map the voice agent's variables to contact fields.
