Good AI receptionist design does not try to automate every caller. The safer model is to decide which calls the agent can complete, which calls it can prepare for a person, and which calls should never stay inside automation.
That is why human handoff is part of the product, not a backup plan added after launch.
The three handoff modes
1. Live warm transfer
Use live transfer when urgency, revenue, customer emotion, or account risk makes a human conversation necessary.
The agent should pass the caller with context: name, intent, urgency, captured fields, and what the caller already said. The caller should not have to restart the story.
2. Callback task
Use callback tasks when the call is important but no person is available immediately.
The task should include the reason for the callback, the preferred time, the caller's details, and whether the issue is urgent. The team should know who owns the task and when it is due.
3. Review queue
Use a review queue for low-confidence answers, failed transfers, unusual requests, and calls that reveal a missing FAQ or broken routing rule.
The review queue is how the workflow improves without guessing.
What should trigger handoff
- The caller asks for a person.
- The caller sounds upset, confused, or unsafe.
- The request is urgent, sensitive, legal, medical, financial, or regulated.
- The agent lacks approved knowledge.
- The caller is high value or already has an open issue.
- The integration write fails.
- The call does not match the configured workflow.
What the team should receive
Every handoff should produce a usable summary. A good summary includes:
- Caller name and phone number.
- Reason for calling.
- Urgency and requested next step.
- Fields captured by the agent.
- Transfer result or callback owner.
- Transcript or recording link when enabled and lawful.
- The reason the agent handed off.
The mistake to avoid
Do not treat handoff as a generic "press 0 for human" escape hatch. That creates vague transfers and noisy callbacks.
The better model is explicit routing: which team, which hours, which backup, which channel, and what information needs to travel with the caller.
Havio maps these rules before launch so the agent knows when to stop and the staff knows what to do next.
