What is a warm transfer?
A warm transfer, sometimes called an attended or assisted transfer, is a way of handing a call from one person to another with care. The first agent puts the customer on a brief hold, calls the colleague or team who can help, explains who the customer is and what they need, and then connects everyone. Often the agent stays on briefly to introduce the customer before leaving the call.
The alternative is a cold transfer (also called a blind transfer), where the agent sends the call to another number or queue without speaking to anyone first. The customer arrives with no introduction, and usually has to explain everything again.
How a warm transfer works
- Decide a transfer is needed. The agent confirms the customer needs someone else, such as a specialist, a supervisor or another department.
- Explain to the customer. The agent tells the customer who they’ll speak to and why, and asks them to hold briefly.
- Consult the receiving party. The agent calls or messages the colleague, summarises the situation and checks they can take it.
- Connect and introduce. The agent joins the customer to the call, introduces them and confirms the key details.
- Hand over and leave. Once the new person has taken over, the first agent drops off and records the transfer.
Computer telephony integration can make this smoother by passing the customer’s record and notes along with the call, so the receiving agent sees the context on screen as well as hearing it.
Warm vs cold transfers: when to use each
Warm transfers suit:
- complex or sensitive issues, including complaints
- vulnerable customers or anyone who is distressed
- safety-related calls, such as hazard calls
- transfers to teams outside the contact centre, where the receiving person may not be expecting the call
Cold transfers can be acceptable for simple redirections to a well-designed queue, where skills-based routing and good data passing mean the next agent already has what they need.
Why warm transfers matter
Being passed around and asked to repeat details is one of the most common customer complaints. Warm transfers reduce that frustration and lower customer effort. They also improve the chances of resolving the issue in one interaction, supporting first contact resolution, and reduce the risk of dropped calls between teams.
The best way to reduce transfers overall is to route customers correctly in the first place. When a transfer is needed, making it warm is the respectful choice.
Warm transfers and AI
The same principle applies when automation hands over to people. A good AI-to-human handover is effectively a warm transfer: the AI voice assistant or chatbot passes the conversation to an agent along with a summary of what the customer has said, what has been tried and why a person is needed. Without that context, automation can leave customers more frustrated than if they’d reached a person straight away.
