Definition
Hot call vs cold call comes down to the prospect's intent. A cold call is a sales call to someone who has shown no interest in the company and is not expecting to hear from it. A hot call is a call to someone who has shown strong, recent interest and expects the call.
On this page, a hot prospect has asked for something specific: a callback, a demo, a quote or a trial, or a conversation at an event. The call exists to answer that request, so the salesperson starts with context the prospect supplied.
Between them sits the warm call, to someone with prior engagement but no request: they downloaded a guide, attended a webinar, accepted a connection on social media, or spoke to a rep last year. The interaction gives the call its reason, but the prospect is not waiting for the phone to ring.
The words describe the prospect's interest, not the rep's mood. A rep can be enthusiastic on a cold call and it is still cold. A list can be expensive and its calls are still cold. Everything else that differs, the timing, the preparation, the opening line and the rules, follows from intent.
This page defines the three, compares them, and points to the deeper Jeluvi guides for each one: scripts for cold calling, the step by step guide on how to make a sales call, and the entry on hot leads, which covers lead temperature in more depth.
Cold, warm and hot calls, side by side
| Dimension | Cold call | Warm call | Hot call |
|---|---|---|---|
| Prospect's intent | None shown | Some engagement, no request | A request: callback, demo, quote, trial |
| Expecting the call | No | Not usually | Yes, and soon |
| Prior interactions | None with the company | A download, webinar, connection, referral or past conversation | The request itself, often with a form or a message |
| Where the contact comes from | An outbound list built from the customer profile | Inbound signals, networking, referrals, past conversations | Inbound requests |
| Timing (this page's view) | On the cadence, one touch among several | Within days of the signal | Within minutes of the request |
| Opening line | The reason for the call, about them | The interaction: the download, the webinar, the note | Their request, repeated back |
| What the rep has to earn | Permission to keep talking | Relevance of the interaction to a real problem | Trust that the answer is coming |
| Goal of the call | A minute, one question, a next step or a clear no | A conversation about the problem behind the signal | Deliver the answer, qualify, set the next step |
| Typical owner | SDRs, on a cadence | SDRs and account reps | Whoever can answer fastest |
Hot call vs cold call: the difference that decides everything else
Three questions place any call on the scale. Did the prospect make a request? Did the prospect have prior interactions with the company? Is the prospect expecting to hear from a salesperson now? A cold call answers no to all three. A hot call answers yes to the first and the third.
The useful test is who started the conversation. On a cold call the company starts it, and the rep supplies a reason. On a hot call the prospect started it, and the rep is replying. Warm calls sit in the middle: the prospect made a move, but toward content, not toward a conversation.
That is why the same rep, the same product and the same phone produce three different calls. The approach changes because the burden of proof changes. On a cold call the rep proves the call is worth a minute. On a hot call the rep proves the company deserves the request it received.
Calls are not fixed in one temperature either. A cold call that connects and ends well becomes the context for a warm call next month. A hot request answered a day late can feel like a cold call to the prospect, who has moved on, or who has heard from other vendors in the meantime.
What is a cold call?
The Cambridge Dictionary defines to cold-call as contacting a possible customer to sell them something "without being asked by the customer to do so." Its Business English entry adds blind call. The Oxford Learner's Dictionary describes a cold call as a phone call to somebody you do not know, made to sell them something.
In B2B sales, cold calling is outbound outreach to prospects who fit the customer profile but have not engaged with the company or its brand. The contact often comes from a prospect list built by the team, and the rep is reaching someone who has no context for the call.
In this page's view, cold calling exists because many good-fit buyers never fill out a form. A team that only calls people who asked can only grow as fast as its inbound marketing. Cold calls reach the rest, as one touch in a cadence with email and LinkedIn.
The structure is short: your name and company, the reason for the call in one sentence about them, a request for a minute, one specific question they can answer, and a next step or a clear no. The Jeluvi guide to cold calling tips covers each phase in detail.
On a cold call a rep should expect to hear no, which is why the call is easier when the reason is real. A hire, a post or a tool change gives the rep something specific to say. A script about the company, read to a stranger, gives the prospect nothing to respond to.
What is a warm call? Warm calling explained
Warm calling is calling prospects who have already interacted with the company but have not asked for a call. Common warm signals include a content download, a webinar registration, an accepted connection request, a reply to a social media post, a referral from a customer, or a past conversation that ended with "not now."
The interaction becomes the opening line. A warm call might start: "You downloaded the cadence template last week, and I wanted to ask how your team handles follow-ups today." This example was written for this page. Opened with a pitch instead, it would be a cold call to a warm lead.
Warm calls carry more preparation than cold calls because the signal implies a problem. Someone who registered for a webinar on email deliverability probably has a question about it. The rep's job is to name that likely problem and ask whether it is real, not to assume it.
A referral is the warmest version of a warm call. The prospect has heard the company's name from someone they trust, and the call opens with that person's name. The relationship belongs to the referrer, so the rep has to protect it by being brief and specific.
Warm call vs cold call
The warm call vs cold call difference is prior engagement. A cold prospect has no previous interactions with the company; a warm prospect has at least one. That single fact changes the first sentence, the amount of research the rep needs, and how the prospect hears the call.
Warm calling is not automatically better than cold calling. Warm calls depend on signals the business already produced, so their volume is limited by inbound marketing, events and referrals. Cold calling reaches prospects who have produced no signals at all, which includes buyers the team would never meet otherwise.
The practical answer, in this page's view, is both, measured separately. Warm calls show which signals predict real interest. Cold calls show whether the prospect list and the reasons behind each call are sound. Blending the two into one connect rate hides both lessons.
What is a hot call?
A hot call is a response to interest the prospect already showed in the product or service. The person asked for a demo, a quote, a callback or a trial, or asked a rep at an event to follow up. The call exists to deliver what they asked for and agree the next step.
The opening repeats the request back, so the person knows why the phone rang: "You asked about pricing for a team of twenty, and I have the answer." This example was written for this page. The call then delivers the answer, and one qualifying question checks fit and timing.
The common mistake on hot calls is treating them like discovery calls, running the prospect through a script of questions when they wanted an answer. The other is routing them through a queue, so the request waits for someone to accept it while the prospect's attention moves elsewhere.
The time from request to callback is set by routing rules and rep habits. This page recommends minutes, not hours, as the target. No response time figure is quoted, because published ones come from vendor studies of their own users. See lead routing for how requests reach a rep.
Hot calls in a contact center
Contact center vendors use the term a little differently. Some describe any call to a customer with an established relationship or a recent inquiry as a hot call, including calls after a past purchase or an unresolved service issue. In that usage, hot means "the agent has context," not only "the prospect asked."
Both usages agree on the core: a hot call is informed by the prospect's own previous actions, and a cold call is not. This page uses the stricter sales definition, a request, because it is the one that changes how fast to call and what to say first.
Where the definitions of cold, warm and hot disagree
No regulator or dictionary checked for this page defines a hot call or a warm call. Neither the Cambridge Dictionary nor the Oxford Learner's Dictionary had an entry for either term when this page was checked. Both define cold call. Hot and warm are sales-team vocabulary, and teams draw the lines in different places.
The main disagreements are about website visits, existing customers and referrals. Some guides call a prospect hot after a pricing page visit; others call that warm. Some count every existing customer as hot. Some treat a referral as hot because the prospect is expecting contact.
The definition matters less than consistency inside one team. If marketing calls a lead hot and sales calls the same lead warm, the lead gets the wrong speed and the wrong opening. Write the team's definitions down, with one example of each, next to the lead status values in the CRM.
| Situation | Label used on this page | Why |
|---|---|---|
| Demo request form submitted | Hot | An explicit request for a conversation |
| Asked a rep at an event to call next week | Hot | A request, with a time attached |
| Downloaded a template or guide | Warm | Engagement with content, no request |
| Visited the pricing page, anonymous | Not a call yet | No person to call until a contact is known |
| Introduced by a customer by email | Warm, close to hot | Expecting contact, but did not ask for a sale |
| Fits the profile, no interaction | Cold | No engagement and no expectation |
| Said "not now" six months ago | Warm | A past conversation the rep can refer to |
Interest, prior engagement and the temperature of a lead
The temperature of a call is the temperature of the lead, and two things set it: how much interest the prospect has shown, and how much prior engagement there has been with the business. Some CRMs model these as two separate scores, one for fit and one for engagement.
HubSpot's lead scoring documentation separates fit scores, built from properties such as job title or company size, from engagement scores, built from actions such as website visits, newsletter subscriptions, call to action clicks or marketing email opens. Thresholds for combined scores use labels from A1 to C3, mixing fit and engagement.
Temperature also cools. HubSpot lets teams turn on score decay, which reduces the points an event contributes as time passes, with intervals of 1, 3, 6 or 12 months. Depending on the setting, an event from months ago can stop counting toward the score entirely.
The practical rule this page draws from that: a hot request on Monday is warm by the end of the week and cold some weeks later if nobody calls. Each kind of calling is a race against the prospect's memory of why they were interested. The hot leads entry covers scoring and signals in depth.
Timing: minutes, days, or the cadence
Timing is where the three kinds of calling differ most visibly. These windows are this page's recommendations, not measured benchmarks.
- Hot calls: minutes. The prospect is waiting, may have the form or email open, and may have contacted other vendors. Route the request to a rep who can call now, not to a shared queue.
- Warm calls: days. Call within a few days of the signal, while the download or the webinar is still in the prospect's memory. A warm call three weeks late can sound like a cold call with an awkward opening.
- Cold calls: the cadence. Cold calls run on the schedule the team set, as one touch among emails and LinkedIn messages. In the Jeluvi 10-day sales cadence, the call is touch 3, on day 4.
Time of day is a separate question. This page quotes no best time to call, because the published figures come from vendor data on their own customers and vary by market. The time that matters is the one your own call logs show for your own prospect list.
Preparation: what a rep checks before each kind of call
| Before a | Check | Decide |
|---|---|---|
| Cold call | Role and company against the customer profile; one current trigger such as a hire, a post or a tool change | The one-sentence reason and the one question to ask |
| Warm call | The interaction: what they downloaded, which session, what the last conversation covered and when | The likely problem behind the signal, phrased as a question |
| Hot call | The request, the account's history in the CRM, existing open deals or tickets | The answer, or the fastest route to it, and the next step to offer |
Cold call research is short by design, a few minutes per prospect in this page's view, because many dials will not connect. Warm call research is about the signal, not the company. Hot call research is about the request, and it should not delay the call.
In all three, plan the follow-up before dialing: the email after a cold call that connected, the resource promised on a warm call, and the meeting invite sent as soon as a hot call ends. The sales call guide walks through notes and recap emails.
Opening lines for a cold, warm and hot call
The opening sentence is where the difference between the three is heard. The lines below were written for this page as examples, with invented names; adapt the reason and the question to your own prospect.
| Call | Example opener | What it does |
|---|---|---|
| Cold | "Hi Dana, this is Sam from Example Co. I saw you are hiring two SDRs, and I am calling about how new reps handle follow-ups. Do you have a minute?" | Names a specific reason about them and asks permission |
| Warm | "Hi Dana, Sam from Example Co. You joined our webinar on cold email last Tuesday. I wanted to ask what made the topic relevant right now." | Uses the prior interaction as context |
| Hot | "Hi Dana, Sam from Example Co. You asked for pricing for a team of twenty an hour ago. I have it, and one question so it is accurate." | Repeats the request and promises the answer |
Each opener states the caller's name and company first. That is good practice on any call, and for many telemarketing calls it is also a legal requirement, covered in the rules section below.
How the conversation runs, and how each call ends
A cold call is a permission conversation. The rep asks one question, listens, and either earns a next step or accepts a no. Pitching before the prospect has said anything turns the call into an interruption. On a cold call to a main line, the first person to answer may be a gatekeeper.
A warm call is a relevance conversation. The rep connects the interaction to a problem and checks whether the problem is real and current. Warm calls end best with a small, concrete next step, such as a short call with the right colleague or a resource tied to what the prospect said.
A hot call is a delivery conversation. The rep answers what was asked, confirms fit with one or two questions, and books the next meeting before hanging up. The lead qualification guide covers which questions belong on that first call and which can wait.
All three should end with a clear outcome written into the CRM: a meeting, a follow-up date, a referral to another contact, or a no with the reason. A call without a logged outcome teaches the team nothing about which approach works.
Cold calling, warm calling and hot calling in a sales team
Many sales teams run all three, and the mix says something about the business. Cold calling is the outbound half: reps calling prospects from a list built on the customer profile. Hot calling is the response to inbound requests. Warm calling connects the two through signals, referrals and past conversations.
The three need different habits. Cold calling needs reps who can open a conversation with someone who did not ask. Hot calling needs speed and routing, because the request is aging while the phone rings. Warm calling needs follow-up discipline, calling within days while the reason is fresh.
A team that wants more hot calls has to produce more requests, which is a marketing question as much as a sales one. The comparison of inbound vs outbound marketing covers how the two motions feed each other, and why neither replaces the other.
The relationship behind each call
Every call sits on a relationship of some depth, and the depth is the real difference between cold, warm and hot. On a cold call there is none yet; the rep is building one from the first sentence, with a reason the prospect recognizes and a question that is easy to answer.
On a warm call there is a thin relationship, a download or a webinar or a note. The rep's job is to name it and build on it rather than start over. On a hot call the relationship is a request, and respect for it means calling fast and answering what was asked.
The next touch inherits whatever the call leaves behind. A cold call that ended politely is the context for a warm follow-up. A hot call handled badly can leave a prospect colder than one who was never called.
How to turn a cold call into a warm call
Most of the work of warming up a cold call happens before the dial. These four approaches are this page's suggestions, each built from steps in the Jeluvi cadence.
The reason in writing, the day and the time, and a way to say no. The call opens with the email. The prospect may not remember it, but the number now has a name.
An accepted connection is an interaction. The call refers to the note, and the profile the prospect checked before accepting has already introduced you.
The trigger is the reason for the call. A reason the prospect recognizes makes a cold call sound considered in the first sentence.
A referral turns a cold contact into a warm one before the first call. Ask only where the relationship is real, and say exactly what the referrer said.
None of these makes a cold call hot. Only the prospect can do that, by asking for something. They do make the first sentence easier for the prospect to accept, which is what separates outreach from interruption.
What US calling rules say about cold, warm and hot calls
This section summarizes the FTC's Telemarketing Sales Rule, the National Do Not Call Registry pages, and the FCC's telemarketing rule at 47 CFR 64.1200, as published when this page was checked. It is not legal advice. Rules on consumer calls, mobile numbers, states and other countries need a lawyer's review.
| Rule | What the source says | Source |
|---|---|---|
| Business-to-business calls | Calls between a telemarketer and a business, to induce a purchase by the business, are exempt from most of the Telemarketing Sales Rule | 16 CFR 310.6(b)(7), FTC guide |
| What B2B calls still owe | The exemption does not cover the bans on misrepresenting material information and on false or misleading statements to induce payment | 16 CFR 310.6(b)(7)(i) |
| Not exempt at all | Calls to induce the retail sale of nondurable office or cleaning supplies, and calls asking employees to buy for their own use | 16 CFR 310.6(b)(7)(ii), FTC guide |
| National Do Not Call Registry | The Registry is for personal phone numbers; business numbers are not covered. Covered sellers remove registered numbers at least every 31 days | FTC consumer FAQ, FTC guide |
| Company do-not-call list | A consumer who asked a seller not to call again may not be called by or for that seller | FTC guide |
| Inquiry-based relationship | An inquiry or application creates an established business relationship for three months, so the seller can return the call even if the number is registered | 16 CFR 310.2(q), FTC guide |
| Calling hours | No telephone solicitation to a residential subscriber before 8 a.m. or after 9 p.m., local time where the call is received | 47 CFR 64.1200(c)(1), FTC guide |
| Identifying the caller | Telemarketing calls to residential subscribers must give the caller's name, the entity the call is for, and a number or address where it can be reached | 47 CFR 64.1200(d)(4) |
| Autodialers and prerecorded voice | Calls to mobile numbers using an autodialer or a prerecorded voice need prior express consent; for telemarketing, prior express written consent | 47 CFR 64.1200(a)(1) and (a)(2) |
| Caller ID | For calls the Telemarketing Sales Rule covers, failing to transmit Caller ID information is a violation | 16 CFR 310.4(a)(8) |
B2B calls: what the exemption covers, and what it does not
The Telemarketing Sales Rule exempts most calls to a business about a purchase by that business. The current rule text keeps two prohibitions for those calls: misrepresenting material information, and making false or misleading statements to induce payment. A B2B cold call is exempt from most of the rule, not from honesty.
The exemption is about the purchase, not the phone line. The FTC guide says calls to business lines that ask employees to buy something for their own use are not business-to-business calls. The FCC rule's autodialer and prerecorded voice limits for mobile numbers contain no business-to-business exception in the rule text.
Some B2B prospects give a mobile number as their main number. Manual dialing by a rep is the safest default this page can suggest for any call to a mobile number, cold, warm or hot. Check with counsel before using automated dialing or prerecorded messages on any list.
Hot calls, requests and consent
A hot call can have a legal advantage that cold calls do not: the prospect asked for it. The FCC rule's definition of telephone solicitation excludes calls made with the person's prior express invitation or permission, and calls to someone with an established business relationship.
Under the Telemarketing Sales Rule, a consumer's inquiry creates an established business relationship for three months. The FTC's example: a company that returns a consumer's call within three months of the inquiry it does not matter whether the number is on the Registry. After that, it needs a transaction or the consumer's express agreement.
A request does not cancel a no. If the prospect later asks not to be called, the FTC guide says the seller must stop, and the FCC rule says a do-not-call request from a residential subscriber is honored for five years. Record the request in the CRM so every rep sees it.
How to measure cold, warm and hot calls
Read separately, the three numbers show where calling works. A cold list that connects but does not convert points to targeting. A hot request that waits a day points to routing. A warm lead called three weeks late points to follow-up.
This page quotes no connect rate, conversion rate or best time to call for any type of call. The published figures come from vendors measuring their own users, with methods that are rarely stated. The comparison that changes what a team does is its own rates, per call type, over a full quarter.
How to choose a calling strategy for your product, market and team
The right mix of cold calling, warm calling and hot calling depends on the business. Three questions shape the calling strategy: who the potential customers are, what the product or service asks of them, and how many leads the brand already attracts on its own. The answers below are this page's view.
- Target audience. If the buyers rarely engage with content or social media, warm leads will be scarce, and cold calling is the main way to reach them. If they research online and engage with your brand, warm calling has more signals to work from.
- Product or service. A product people already search for produces inbound requests, and hot calls follow. A new category, or a service buyers do not know they need yet, may need cold outreach to start the conversation.
- Market conditions. In a crowded market, speed on hot calls matters more, because the prospect is comparing vendors. In a quiet market, a salesperson making well-researched cold calls may reach buyers no competitor has contacted.
- Team and data. Warm calling depends on engagement data the CRM can show a rep before the call. Without that data, a warm lead looks like a cold one, and the rep loses the context that made it warm.
Whatever the mix, the approach for each call should match the lead's temperature. Treating hot leads like cold ones wastes their interest, and treating cold leads like hot ones assumes interest that is not there. Success on each kind of call means something different, so the strategy has to define it for each.
What success looks like on each call
On a cold call, success is a conversation with a clear outcome: a next step, a referral, or a no with a reason. On a warm call, success is confirming whether the problem behind the signal is real. On a hot call, success is a booked meeting or an answered request within the prospect's timeline.
Judging all three by meetings booked makes cold calling look like a failure and hot calling look easy. Judging each by its own goal shows whether the outreach is working, and which leads deserve more of the sales team's time.
When to use a cold call, a warm call or a hot call
The prospect decides which kind of call you are making. What the team decides is where to spend rep time. The guide below is this page's view.
| Situation | Call to make | First move |
|---|---|---|
| A demo, quote or callback request arrives | Hot call | Call now; everything else waits |
| A good-fit contact engaged with content this week | Warm call | Call within days, open with the interaction |
| A customer offers an introduction | Warm call | Confirm what the referrer said, then call |
| A new account fits the profile, with no signals | Cold call, inside a cadence | Email first with the reason, then call |
| A market where inbound is thin | Cold calling, sustained | Build the list from the profile, see outbound lead generation |
| A past prospect said "not now" | Warm call, on the date they gave | Open with the last conversation |
Mistakes with hot, warm and cold calls
These are the mistakes that make cold calling look worse than it is and hot calling slower than it should be.
- Calling a cold list "hot leads." The price of a list says nothing about the prospects' intent.
- Running a hot call like discovery. The prospect asked a question; answer it before asking yours.
- Letting a hot request wait in a queue. Route it to a person who can call now.
- Cold calling without a reason. A script about the company gives the prospect nothing to respond to.
- Calling a warm prospect weeks after the signal. The interaction no longer works as an opening line.
- Pretending a cold call is warm. "Following up on our conversation" when there was none breaks trust, and on a B2B call it can be a misrepresentation.
- Skipping the do-not-call checks. Keep the company list current and check the Registry for consumer numbers.
- Measuring all three with one number. It hides whether the cold list or the hot routing is the problem.
In a sequence
In the Jeluvi 10-day cadence, the call is touch 3 on day 4, after a first email on day 1 and a LinkedIn connection note on day 2. Those two touches are what make the call less cold, even if the prospect never replied.
The email below was written for this page. It is a variant of the day 1 email that gives the reason, says when the call is coming, and offers a way to say no, so the call opens with a reason the prospect has already read.
Subject: Calling Thursday about the SDR ramp at {{company}} Hi {{firstName}}, Saw the two SDR openings at {{company}}. The first quarter with new reps is often where follow-up touches get dropped, and we keep a one-page cadence built to prevent that from day one. I will call Thursday morning for five minutes to ask one question about how your ramp works today. If Thursday is bad, reply with a better time, or with "no" and I will not call. {{senderName}}
The email promises Thursday and the call comes Tuesday, or comes from a number the prospect cannot match to the email.
Then the call is cold again, and worse, because the prospect remembers the promise. Call when you said, from a number with a name, and open with the email.
Frequently asked questions
What is the difference between a hot call and a cold call?
Hot call vs cold call comes down to the prospect's intent. On a cold call the person has shown no interest and does not expect the call, so the rep has to earn the first minute.
On a hot call the person asked to be called, and the rep's job is to respond fast.
What is a hot call in sales?
A call to someone who has shown strong, recent interest and expects to hear from you: they requested a callback, a demo, a quote or a trial, or asked a rep at an event to follow up.
The opening refers to their request, and the call delivers what they asked for.
What is a cold call?
An unsolicited sales call to someone who has not interacted with the company and is not expecting it. Cambridge defines cold-calling as contacting a possible customer to sell something without being asked. In B2B, a cold call works best as one touch in a cadence, with a real reason.
What is a warm call?
A call to someone who has engaged with the company but has not asked to be called: they downloaded a guide, attended a webinar, accepted a connection request, were referred, or spoke to a rep before. The opening refers to that interaction instead of introducing the company from scratch.
What is the difference between a warm call and a cold call?
Prior engagement. A warm prospect has at least one interaction with the company, such as a download, a webinar or a referral, and the call opens with it. A cold prospect has none, so the rep has to supply the reason for the call in the first sentence.
What is the difference between a warm call and a hot call?
A warm prospect did something; a hot prospect asked for something. The warm call opens with what they did and offers a reason to talk. The hot call opens with what they asked for and delivers it, ideally within minutes rather than days.
Is warm calling better than cold calling?
Warm calls start with context, so the first sentence is easier. But warm calling is limited by how many signals the business produces, and cold calling reaches buyers who have produced none. Most teams need both, measured separately, so each one shows what is working.
How fast should you call back a hot lead?
This page recommends minutes, not hours, after the request arrives, because the prospect is waiting and may contact other vendors. Response time figures published by vendors measure their own users, so track your own minutes from request to call and fix routing first.
How do you turn a cold call into a warm call?
Create an interaction before the call. Send an email that names the reason and says when you will call, connect on LinkedIn with a short note, call on a trigger the prospect will recognize, or ask a mutual contact for an introduction. Then open the call with that touch.
What should you say on a hot call?
Repeat their request so they know why you are calling, give the answer or the fastest route to it, ask one qualifying question about fit or timing, and agree the next step with a date. Do not run a hot call like a discovery script.
Do do-not-call rules apply to B2B cold calls?
The FTC says the National Do Not Call Registry is for personal numbers and does not apply to business-to-business calls.
Most B2B calls are exempt from most of the Telemarketing Sales Rule, but not its bans on misrepresentation, and calls selling nondurable office or cleaning supplies follow most of the rule, though not its Registry provisions.
Can I call someone on the Do Not Call list who filled out my form?
Under the Telemarketing Sales Rule, an inquiry creates an established business relationship for three months, so the FTC says Registry status does not matter for returning that call. After three months you need a transaction or their express agreement. If they ask you to stop, stop.
Is a referral a warm call or a hot call?
Usually a warm call. The prospect has heard your name from someone they trust and may expect contact, but they have not asked for a sales conversation. Open with the referrer's name and what they said, and keep the call brief to protect that relationship.
What is a hot call in a call center?
Some contact center vendors use hot call for any outbound call to a person with recent interest or an existing relationship, such as an inquiry or a past purchase. The agent has context from previous interactions. Sales teams tend to use the stricter meaning: the prospect asked to be called.
