A handoff is the moment an AI stops and a person starts. Done well, the customer barely notices. Done badly, it undoes the value of the automation and adds a frustration the customer did not have before. These five requirements define “done well.” Use them to evaluate any vendor, including Redial.
Requirement 1: The Business Sets the Triggers
A handoff should happen when the business says it should, not only when the AI gives up. There are four kinds of trigger, and the business should control all of them:
- Caller request. Always honored, immediately, in any supported language. This is non-negotiable; 85% of consumers want a person reachable, and the inability to reach one is the top complaint about automation 1 2.
- The request is outside what the AI is configured and permitted to do.
- Categories the business decides always go to a person: payments, complaints, clinical or legal questions, cancellations, existing disputes.
- Repeated misunderstanding, frustration, or an emergency keyword.
How it fails: vendors ship defaults and the business never reviews them, so payments go to the AI and routine bookings go to people. Ask the vendor: show me the trigger configuration and who can change it.
Requirement 2: The Transfer Is Warm, Not Cold
In a warm handoff the caller is told a person is joining and that the person already has the details, and the person continues the conversation. In a cold handoff the caller is transferred into a queue and starts over. Some vendors now describe warm transfers that carry caller, reason, address, and CRM status to the person taking over 3; that is the specificity to expect.
How it fails: the “handoff” is a transfer to a general line, or a text message to an owner who is on a job. Ask the vendor: what does the caller hear between the AI and the person?
Requirement 3: The Conversation Travels
The person taking the call should receive, before speaking: who is calling and how they were identified; why they called, in their own words; what the AI already did (times offered, information looked up, address confirmed); why the handoff was triggered; and the language of the conversation. Zendesk found 81% of consumers want agents to continue a conversation without backtracking 4.
How it fails: a transcript exists somewhere but the person cannot see it in time, so they ask. Ask the vendor: show me the screen the person sees at the moment of handoff.
Requirement 4: The Caller Is Told They Will Not Repeat Themselves, and Then They Don’t
This is the moment the customer judges. The AI should say, in effect, “I am bringing in a colleague who has everything you have told me,” and the colleague should prove it with their first sentence. 74% of consumers are frustrated when they have to repeat information [4]; a handoff that forces it is worse than no AI at all.
How it fails: the person opens with “How can I help you today?” Ask the vendor: how do you check whether agents are asking callers to repeat information already given?
Requirement 5: The Handoff Is Measured
Three measures turn the standard into something you can hold a vendor to: handoff rate by reason, time to human in seconds, and context carried (the share of handoffs where the person did not ask for anything already given, scored in QA). In one AI receptionist vendor’s data, 73.8% of the AI’s actions were transfers to a person 5, which shows how much traffic the handoff path carries and why it deserves its own numbers. California’s AB 1609 now sets 15 minutes as the human-access standard for the largest businesses 6; a front desk should be in seconds.
How it fails: nobody measures it, so “human in the loop” stays a slogan. Ask the vendor: what is your measured handoff rate, time to human, and context-carried score, over what period?
The Checklist
| Requirement | Ask the vendor | Good looks like |
| Business sets the triggers | Show me the trigger configuration | Caller request always honored; policy categories set by the business |
| Warm, not cold | What does the caller hear between AI and person? | Introduction, then continuation |
| Conversation travels | Show me the person’s screen at handoff | Identity, reason, actions taken, trigger, language |
| Caller told they won’t repeat | How do you check agents don’t ask for repeats? | QA item scored on every sampled handoff |
| Measured | Handoff rate, time to human, context carried? | Numbers, with period and call count |
How Redial Fits
Redial applies these five requirements to its own staffed programs and to the AI front desk it is previewing, IzzyOps (working name), which is designed so that when a digital agent cannot resolve a call it hands off to a person with the conversation history attached 7. The person can be the client’s team or a bilingual Redial agent in a US time zone. Redial will publish its measured handoff rate, time to human, and context-carried score from pilot programs rather than assert them.
Frequently Asked Questions
What is the most important of the five requirements?
Requirement 4, because it is the one the customer experiences directly. The other four exist to make it possible.
Should a caller always be able to reach a person?
Yes, on request. Policy and scope triggers are additional, not alternatives. Making a person unreachable is the top annoyance consumers report about automation 2.
What is a reasonable time to human?
For a front desk, seconds. California’s AB 1609 sets 15 minutes as the standard for the largest businesses 6, which should be read as a ceiling, not a target.
How do I verify a vendor’s claims about handoffs?
Ask for a live or recorded demonstration of a handoff, look at the screen the person sees, and ask for the three measures with a period and a call count. Specific answers mean the standard is real.

Put the Five Requirements to the Test
Book a demo of IzzyOps (working name), the AI front desk Redial is previewing, and check each requirement yourself: the triggers, the warm transfer, what travels, what the caller is told, and how it is measured. Commercial availability is planned for late 2026 to early 2027.
