Design a virtual-agent handoff as a transfer of responsibility for an unfinished customer task. A transfer event alone is insufficient: define who receives the request, what they know, and what happens if nobody accepts it.
Level AI documents voice/chat virtual agents and workflow controls. Genesys describes contextual handoffs to human agents. Those descriptions establish topics to investigate, rather than evidence that a particular queue receives every field your workflow needs.
What should the handoff contract contain?
A handoff contract is the agreed information and behavior at the boundary between automation and a person. Write it before configuring the transfer. Keep customer statements, verified system facts, and the AI's interpretation separate so the receiving agent can judge the evidence.
| Contract field | Acceptance evidence |
|---|---|
| Reason and destination | The requested task and intended queue appear together |
| Verified context | Confirmed identifiers and completed checks retain their source |
| Actions attempted | Outcome distinguishes completed, rejected, and unknown |
| Unfinished work | The next required action is readable and specific |
| Ownership | A receiving agent or queue acknowledges the case |
Include a link to the relevant conversation segment where available. Avoid making the agent read an entire transcript to find one unresolved question. Equally, do not treat a short generated summary as a substitute for the underlying evidence.
Which handoff triggers require different treatment?
Separate an explicit request for a person from repeated misunderstanding, an unsupported task, and a failed system action. A caller who asks for a person should not need to fail an arbitrary number of automated turns first. A failed action should carry its uncertainty, rather than restarting the same action silently after transfer.
- Test the ordinary queue while a receiving agent is available.
- Repeat with no available agent and with the queue closed.
- Interrupt the transfer and reconnect through another channel.
- Transfer after an action whose final state is unknown.
- Ask the receiving agent to explain the next step without questioning the customer again.
How should an unavailable human fallback work?
Specify the permitted fallback for each situation: another supported queue, an offered callback, a case for later follow-up, or a clear explanation that immediate help is unavailable. These are design options, not features assumed to exist in every platform. Preserve the customer's choice and avoid promising a response time the operation cannot support.
Record the attempted destination, acknowledgment time, actual destination, and whether required context arrived. Review cases that created duplicate tickets or sent the customer back to the bot. Treat an accepted case with no useful context as a partial failure.
What should the operator approve?
Approve a versioned handoff contract and a named owner for queue changes. Recheck it when routing, case fields, task permissions, or receiving-team processes change. For the preceding voice interaction, use the interruption test plan; for uncertain actions, use the recovery decision table.
What context packet should the receiving agent acknowledge?
Use a compact task packet rather than sending an unexplained transcript. The following is an illustrative field contract, not a claim about a vendor's default export.
| Field | Illustrative content |
|---|---|
| Task and unresolved request | Delivery address correction; final write state unknown |
| Verified and unverified details | Order located; required confirmation completed; replacement address provided but write unconfirmed |
| Action evidence | Action ID, attempt time, timeout and latest readback result |
| Customer promise | No completion promise made; update owner and next communication recorded |
| Receiving acknowledgment | Queue, assigned owner, receipt time and usable evidence access |
Minimize sensitive content and link to authorized records instead of duplicating whole customer profiles. A successful routing event is insufficient when the agent cannot open the evidence or does not know which action is unresolved.
Run two acceptance cases: the destination is staffed and accepts ownership; the destination is unavailable. In the second case, preserve the task in a supported queue or case with a communicated next step. Do not count a disconnect as a completed handoff merely because a transfer command was sent. Measure packet completeness and customer resolution separately.
Limits
This is a recommended operational contract, not a measurement of vendor transfer success. Public descriptions do not establish available payload fields, queue integration, availability, or ownership behavior. Confirm those details with a working end-to-end transfer in your own environment.
