Useful minimum integration
The useful minimum integration is your phone number, the agent, your webhook or backend and the panel.
That is already enough to show a complete and realistic flow.
What actually gets connected
What gets connected is the call, its transcript, its summary and the structured incident.
That is what makes the demo feel like a product instead of just a nice phone call.
What can wait
ERP, BI, deeper automation or corporate integrations can wait.
Before that, it is better to validate whether the pain is real and whether the pilot works.
