What Is a Warm Transfer? Warm Transfer vs Cold Transfer Explained

call center workers transferring customer calls

Few things are more frustrating than calling a business or contact center, explaining the reason for your call, getting transferred to another agent – then having to start again from scratch 😠 

This is an all-too-common experience. But transfers don’t have to spell bad news for the caller. In fact, warm transfers often speed up resolution times, resulting in better outcomes for everyone.

What are warm transfers? 😊

A warm transfer happens when an employee realizes that they’re not the best person to handle a customer’s query. So they reach out to a colleague (often in a different department and/or a more senior role), share relevant details about the query, then transfer the call – that way, the caller doesn’t have to repeat themselves. 

Here’s a more detailed look at the warm transfer process:

👉 Step #1: Caller gets through to employee #1 and explains the purpose of their call.

👉 Step #2: Employee #1 captures the key details and explains that a colleague can help with the caller’s query.

👉 Step #3: Employee #1 places the caller on hold and speaks to employee #2, explaining the reason for the call and sharing any other key details (like previous issues the caller has got in touch about). 

👉 Step #4: Employee #1 tells the caller that they’re about to be transferred.

👉 Step #5: Employee #1 stays on the line, introduces employee #2, then dials off.

👉 Step #6: Employee #2 (briefly) shares the reason for the call, asks further questions as necessary, then sets out next actions.

Not only does it make for a better customer experience, but it also leads to swifter resolution times. Everyone wins.

The difference between a warm and cold transfer 🤔

As you likely guessed, a cold transfer – also known as a blind transfer – is the polar opposite of a warm transfer.

Rather than providing a kind of concierge service for the caller, cold transfers either involve the caller being transferred to a different employee with zero introduction, or worse, passed to a ringing line and left to wait on their own.

After which they have to explain the purpose of their call all over again.

When to use warm and cold transfers 🔁

On the face of things, warm transfers are clearly better than cold ones. They make the customer feel more special and cut out pointless repetition, meaning everything gets sorted faster and in a friendlier manner. So they’re always the best option, right?

Not necessarily. There are scenarios in which cold transfers are the smart choice, such as when a business employs a receptionist to answer calls.

When should you use warm transfers?

Warm transfers are the preferred choice for contact centers, where a caller might think their query is aimed at one department – but, in reality, it’s better handled by a different department. 

For example, say a home services business has one department handling sales and another for active accounts. A customer who’s recently scheduled an appointment might want to change it, so they call through to the sales team who handled their original query. But actually they should be speaking to the accounts team, so they get a warm transfer to the correct department 🤝 

When should you use cold transfers?

By contrast, cold transfers are generally the best fit for businesses with a receptionist, an answering service, or some other form of call handling solution. Especially if the business deals with complex, technical topics that a “layperson” would struggle to discuss, like accounting or law.

In those scenarios, the person who first answers the call likely lacks any expert knowledge of the subject matter. So the best thing they can do is find out the broad reason for the call, then pass the caller onto a specialist as quickly as possible.

The benefits of a warm transfer ✅

While warm transfers aren’t the right choice in every scenario, they generally feel friendlier, more professional, and more human. Plus a well-executed warm transfer can lead to faster call resolution times, keeping your customers happy and boosting your efficiency and productivity.

Less repetition

Repetition is bad for all parties. It wastes time, making your business less productive. And it frustrates your customers, which means they’ll be less patient when it comes to solving their queries.

In the worst-case eventuality, callers could get so annoyed that they decide they simply don’t want to do business with you any longer. In which case you’ve lost a valuable customer.

More accurate transfers

A less obvious benefit of warm transfers is that they more-or-less eradicate the risk of accidentally misdirecting calls. Think about it: the employee who originally answered the call has taken the time to speak to a colleague, then stay on the line to introduce the caller – so there’s little chance of them somehow sending the caller to a random department. And even if they do get it wrong, they’ll still be present to correct their mistake.

More personalized interactions

Personalization has rapidly become a crucial element of customer support. Per McKinsey:

👉 71% of consumers expect companies to deliver personalized interactions

👉 76% feel frustrated when interactions aren’t personalized

👉 72% expect the businesses they buy from to recognize them as individuals and know their interests

Warm transfers feel more personal than cold ones because the employee who receives the transfer gets to greet the caller by name and explain that they understand the reason for their call.

Faster issue resolution

To be clear, warm transfers won’t automatically improve resolution times. A receptionist at a law firm probably won’t speed things up by discussing a caller’s complex legal issue with a senior partner – they just need to identify the purpose of the call and transfer it to the right person, ASAP 🏃‍♀️ 

However, warm transfers cut down on repetition and ensure the employee who ultimately handles the call has a clear understanding of what’s required. Which, in turn, can lead to faster resolutions.

More "human" customer support

Warm transfers make the process of passing a caller from one employee to the next feel more like a human conversation between multiple parties. They also make the caller feel more valued than simply placing them on hold or transferring them to a dial tone.

Best practices for smoother warm transfers 👍

While warm transfers can produce positive results, they aren’t a silver bullet for better customer support. Get them wrong and they can feel just as frustrating and jarring as a cold transfer – just with an extra agent on the line. 

For best results, train your sales team on effective warm transfer techniques, be transparent with the caller, and ask for a callback number in case anything goes wrong.

Train your support team

Obvious as it sounds, your first port of call is to ensure your team knows exactly how to conduct a successful warm transfer. Your training should cover:

📄 Scripting: What should the agent ask the caller before transferring them to a colleague? And how should they hand the call over to the person who’ll ultimately handle the query?

⚙️ Technical issues: What technical steps does an agent have to follow to place a caller on hold and transfer to a colleague without cutting off the caller?

🔧 Recovery: Mistakes happen – so what steps should the agent take if a caller does get disconnected?

As well as training existing agents, make warm transfers a standard part of your onboarding process so new starters get up to speed fast.

Use AI solutions to streamline call transfers

Artificial intelligence can help you achieve friction-free warm transfers. For instance, a virtual assistant can act as a receptionist for your business, capturing the customer’s information and finding out the reason for their call before transferring them to a human agent.

Share all the necessary context

Communication between team members is crucial to delivering effective warm transfers. If the agent who answered the call doesn’t share all relevant context with the employee they pass the call to, the caller will still end up having to repeat themselves – and that makes for a frustrating experience for everyone.

The specifics of what information you need to share will vary from business and scenario to the next. But, as a minimum, your agents should be communicating the:

👉 Caller’s name

👉 Reason for their call

👉 Issue history (i.e. have they contacted your business about this issue before? And, if so, what was the outcome?)

Armed with all this information, your employees should be able to deal with most queries without much – if any – backtracking.

Get permission before transferring the call

Warm transfers might be second nature to you and your employees. But they’re likely less familiar to your customers. As such, you should always explain what’s going on and ask for the caller’s permission before making a warm transfer – including letting them know that they’ll be placed on hold for a short time while your agents discuss the issue.

Ask for a callback number

For some businesses, requesting a callback number is standard practice at the start of any call. But even if it’s not part of your standard best practices, you should definitely capture the caller’s number before attempting a warm transfer. 

Sure, most of the time you won’t need it – but better safe than sorry.

Check the recipient is available

When carrying out a warm transfer, don’t just sit on hold with the caller hoping that your colleague picks up – speak to them first to confirm they’re available. That way, you can always try to find a different colleague to help, or ask to call the customer back later.

It’s all about minimizing the amount of time they spend waiting around for a solution.

The bottom line ✍️

Warm transfers are often the preferred choice for resolving customer queries because they’re friendly and cut out repetition, making for a better customer experience. Just be sure to define your warm transfer process and train your agents on it, including:

👉 Requesting a callback number

👉 Asking the caller’s permission before transferring them

👉 Ensuring the second agent has all the necessary information to handle the caller’s query

FAQs

What is an example of a warm transfer?

An example of a warm transfer is when a customer calls your business and speaks to an agent in your billing department. However, their query is actually for your projects team. So the initial recipient places the caller on hold, rings through to the projects team to explain the issue, then transfers the call and introduces the caller to their colleague.

Are warm transfers better for your business?

Warm transfers are often better for businesses as they feel friendlier, make for a more positive customer experience, and can increase first-contact solution resolution rates. However, cold transfers are the best choice in some scenarios. For instance, if you employ a receptionist, it might be best for them to simply ask why the customer is calling, then cold transfer them to a relevant team member.
