TL;DR
When reps say nobody is picking up, check the phone number they're calling from first. Call analytics companies that work with the carriers can label a number "Spam Likely" or filter it before it rings, and the rep sees nothing wrong from their side.
The fastest check takes about 30 seconds: call a phone you own from the rep's number. If it doesn't ring, or is labeled as spam, the number has likely been flagged. Each analytics company runs its own analysis, so test on more than one carrier.
Generated numbers and Google Voice lines connect less often than a number the rep owns. Registering business numbers with the Free Caller Registry reaches Hiya, TNS and First Orion at once, though it doesn't guarantee a fix.
If the number checks out, look at the list: dead numbers, front desks and the wrong person. Belkins counts those pickups as connects, so a list problem can hide behind a normal-looking connect rate.
A normal connect rate is around 10% per dial in Belkins' 2025 B2B data, so most calls not connecting is expected. A drop from a rep's usual rate is what to investigate.
If the number and the list check out, compare the rep's call log against the CRM. Calls made from the road may never get logged, so a low connect rate may only exist in the report.
Most sales managers have heard some version of this in a one-on-one from a frustrated rep: "Nobody's picking up. Why aren't my cold calls connecting?"
The rep is making the necessary number of calls - from the truck between site visits, from the office, from a dialer - but first meetings aren't getting booked.
It's natural to start with what you can "coach”: the effort, the opener, the script, the time of day they're calling. That's the right place to start.
But sometimes the issue is a deeper one. And it's usually hidden in one of three places: the phone number, the list or the activity report.
Each shows up differently on the calls, and the cheapest one to rule out takes about 30 seconds.
Across more than 175,000 B2B dials in 2025, counting any live answer as a connect, the connect rate was 9.9% per dial and 24.5% per prospect (Belkins, 2026).
In an analysis of more than 300 million cold calls, the average rep connected on 5.4% of dials, and top-quartile reps on 13.3% (Gong, 2024).
86% of unknown calls go unanswered, in a survey of more than 12,000 consumers across six countries (Hiya, 2026).
As many as 88% of enterprise calls are not answered, according to figures cited by the FCC (FCC, 2025).
What's a Normal Cold Call Connect Rate?
A normal cold call connect rate is around 10% per dial. In a 2025 study of more than 175,000 B2B dials, Belkins found a live person picked up on 9.9% of calls, and about one in four prospects picked up at least once across repeated calls.
The second number is the one that matters for a list, because it takes several calls to reach most people.
Ben Walters, Sales Leader at Convex, sees the same pattern on his team: "Of the people who pick up the phone, I think it's one in four, one in five. You want to be calling them four or five times over a two to three week period to ensure you have the conversation."
It's also why Ben's range for the number of touches it takes to book a meeting runs from eight to fifteen, across phone, email and in-person visits.
Take a second and run that outbound motion against the one your team is using today.
Say a rep makes 100 cold calls a week. At a 10% connect rate, about ten people pick up, and at Belkins' rates, that's well under one booked meeting a week from those calls alone.
To see what a lower connect rate does to meetings booked, plug your team's numbers into a pipeline calculator.
So even a rep doing everything right hears mostly silence, and that's what they bring into the one-on-one.
Taj Shaw, Manager of Customer Success at Convex, hears a similar frustration quite often: "Sometimes I get on calls with reps and they're like, I left voicemails and nobody called me back, I sent emails and nobody responded. Sometimes I have to set the real perspective of - in your Gmail, how many unanswered emails do you have from people reaching out to sell you things? It's very similar to that."
A low connect rate on its own is normal. What matters is a drop from a rep's usual rate, and that's harder to spot than it sounds.
Many activity reports show dials and meetings but not why calls didn't connect, and calls from a personal cell may not be logged in the CRM if they’re calling from the road.
In ServiceTitan's 2025 survey of more than 1,000 commercial sales and service managers, 22% said their CRM's reporting was limited (ServiceTitan, 2025).
When activity reports can't show why calls failed to connect, there are 3 key places to look.
Connect rate: The share of dials where a live person picks up. Some studies count anyone who answers, including a gatekeeper or the wrong person, and others count only the prospect. Per dial counts every call. Per prospect counts each person reached at least once.
Call labeling: A warning such as "Spam Likely" that a call analytics company working with a phone carrier shows on the receiving phone, or a filter that stops the call before it rings.
Flagged number: An outbound number that a call analytics company's own analysis has marked as likely spam. Legitimate business numbers can end up flagged.
Why Aren't My Cold Calls Connecting? Three Places to Look
When a rep's calls aren't connecting, there are two primary reasons: the phone number they're calling from, or the list they're calling. A third thing can make it look like calls aren't connecting when they are: inaccurate activity reports.
A flagged number is the hardest of the three to catch. The call shows up as “Potential Spam,” or "Spam Likely," or the call gets filtered before it even rings on the recipient’s end.
On the rep's end, it just sounds like nobody picked up.
Nothing in the CRM or dialer records that label, so the activity report looks the same as it would if no one picked up the call. The only way to see what prospects see is to have the rep call a phone you own and check how your caller ID identifies them.
A bad list is easier to identify. It will show up in the notes section as: “dead number,” “main line” and “wrong person”.
And sometimes the calls are connecting, but they never make it into the CRM, especially calls made from the road with notes that were filled in later as an afterthought.
The table below shows what each one looks like and the first thing to check.
What you see | Likely cause | First check |
Nobody picks up, and test calls ring through as potential spam | The number | Call a phone you own from the rep's number and check how your caller ID shows it |
The number is dead or disconnected, or it rings at a main line, a front desk or the wrong person | The list | Pull 20 recent dials from the CRM or dialer, or have the rep log their next 20, and note who actually answered |
The CRM shows dials with few connects, but the rep says they're reaching people, or calls made from the road never show up | Activity data | Compare a week of the rep's phone or dialer call log against what's in the CRM |
Most connect-rate benchmarks count every live answer as a connect, including a front desk or the wrong person. So a team's connect rate can look normal while reps aren't reaching anyone who can say yes.
Start at the top of the table. The number is the cheapest cause to rule out, but it's the one a rep can't spot from their own phone. Unknown numbers already have a hard time getting answered, as we covered in our look at declining cold outreach, and a number labeled as spam has even less of a chance.
So how do you know if a rep's number is the problem?
Is Your Number Flagged as Spam?
The quickest way to find out is to call a smartphone you own from the rep's number and see whether it rings through. Call analytics companies working with the carriers can filter a number before it rings, and the rep never sees it happen.
Hiya, TNS and First Orion are three of the companies that label and filter calls for carriers, each running its own analysis, and even the FCC has said it wants fewer "lawful calls that incorrectly are identified as fraudulent."
David Vroblesky, Principal Product Manager at Convex and ServiceTitan, heard about this from someone using Convex. She was getting a lot of non-answers on her calls, so she looked David up and called him. His cell phone didn't ring at all. She went into her settings, imported a new number, called again, and it went right through.
"She had a Google Voice number connected to Convex that had gotten flagged as a spammer, so it was automatically getting filtered out." - David Vroblesky, Principal Product Manager, Convex and ServiceTitan
Notice the order of what she did. She called someone outside her team first, and only changed the number after his phone didn't ring. That's the 30-second check.
A ring doesn't fully clear a number, because each analytics company runs its own analysis, so it helps to test on phones from more than one carrier.
The type of number matters, too. As David puts it, "Your phone number has a much higher likelihood to actually get connected than some of these generic generated phone numbers. The actual number that you call from can determine how likely it is to connect."
For a commercial services rep, who makes far fewer calls than a software SDR, a generated number or a Google Voice line is a likelier place to look than how many calls they make.
If your team calls through a tool like Convex, a rep can import their own number in settings and call from it, so the number prospects see is one the rep has already tested.
Registering your business numbers with the Free Caller Registry gets them to Hiya, TNS and First Orion at once, before there's a problem. It's free, though the registry is clear that registering "does not guarantee redress."
If test calls ring and reps still aren't reaching the right people, the next place to look is the list.
Is the Problem the List?
When calls ring at dead numbers, front desks or the wrong person, the list is the problem.
Belkins found 13.5% of unsuccessful outcomes were the wrong person or a wrong number, and another 13.4% stopped at a gatekeeper. Belkins counted those calls as connects, which is why a list problem can hide behind a normal-looking connect rate.
Nick Davis, Chief Strategy Officer at MSD, a mechanical contractor in Dayton, Ohio, saw this before Convex. His reps made 100 cold calls a week, researched prospects at the local library and usually got only a main phone number, so most of those calls stuck at the gatekeeper.
"We were losing time that we weren't going to get back," Nick said.
Every dial to a main line is time spent on bad contact data instead of the person who makes the decision. As David puts it, "Anytime you get into this world of cold prospecting, the data is never perfect... but there is a spectrum of better or worse."
So the useful question is where your list sits on that spectrum.
If most of a rep's 20 logged dials reach a front desk and they’re not getting through, getting past the gatekeeper starts with a list built around decision-makers' verified contact information, not the main line.
And if the number and the list both check out but the report still looks wrong, the next place to look is the activity report itself.
Do Your Activity Reports Match the Calls?
Sometimes the calls are connecting and the report doesn't show it. Calls made from a personal cell on the road may never reach the CRM, and activity logged after the fact doesn't always match what happened.
A rep calling from the truck between site visits is doing the work. But if the dialer or CRM isn't on that phone, those calls don't exist in the report. And when activity gets logged at the end of the day or the end of the week, some calls get missed and activities get marked complete that never happened.
Either way, you're coaching from a report that doesn't match a rep’s actual prospecting.
Matt Koenig, General Manager at Haynes Mechanical Systems in Colorado, needed every rep booking five new meetings a week to hit service targets, and he had very little visibility into whether it was happening.
His team started tracking first appointments booked, buildings tracked, and proposals moving forward, and the Haynes case study shows what happened because of this shift.
Matt’s summary is:
"Now we can control a leading measure we need to achieve a lagging measure. Convex helps us identify the activities that help us get the meetings." - Matt Koenig, General Manager, Haynes Mechanical Systems
The check here is simple. Compare a week of the rep's call log on their phone or dialer against what's in the CRM. If they match, the connect rate is real. If they don't, the low connect rate may only exist in the report.
What to Check Before Your Next One-on-One
Check the three places in order: the number, then the list, then the activity data. The first check takes about 30 seconds, and it's the fastest way to test the cause nobody on the team can see.
Take these four questions into your next one-on-one, alongside the sales metrics you already review:
Does a test call from the rep's number ring through?
What does the caller ID say?
Of the rep's last 20 dials in the CRM or dialer, or the next 20 they log by hand, how many reached the person and actually connected?
Does the call log on the rep's phone or dialer match what's in the CRM?
David's user got through by switching numbers, MSD's reps eliminated the wasted effort, and Haynes started tracking the activities that lead to meetings.

Frequently Asked Questions on Cold Calling
Why are my cold calls going straight to voicemail?
Most people don't answer unknown numbers. In Hiya's 2026 consumer survey, 86% of unknown calls went unanswered. Calls can also be filtered before they ring when a call analytics company has labeled the number as likely spam. To tell the difference, call a phone you own from the rep's number. If it doesn't ring, or is labeled as “Potential Spam,” the number is the likely problem.
What is a good cold call connect rate in 2026?
Connect rate is the share of dials where a live person picks up, and Belkins counts a gatekeeper or the wrong person as a connect. Belkins' 2025 data put it at 9.9% per dial and 24.5% per prospect. Gong's larger analysis found the average rep connected on 5.4% of dials and top-quartile reps on 13.3%, so benchmarks shift with how they're counted. Your own trend matters more: how does each rep compare to their own recent weeks?
How do you know if your number is flagged as spam?
Call a phone you own, or a colleague who will pick up, from the number your rep uses. If it doesn't ring or shows a warning like "Spam Likely," the number has likely been labeled. Each analytics company runs its own analysis, so a ring on one phone doesn't fully clear the number. Test on more than one carrier if you can.
How do you prevent outbound numbers from being flagged as spam?
Register your business numbers with the Free Caller Registry, which reaches Hiya, TNS and First Orion at once, and call from a number the rep owns rather than a generated one. Showing who's calling, where your carrier or calling tool lets you, helps too: the FCC cites figures showing 73% of consumers will answer when the caller's name is presented. Registration isn't a guarantee.
How many cold calls does it take to get a connection?
Belkins averaged about three dial attempts per prospect in its 2025 data. Ben Walters, Sales Leader at Convex, suggests calling each prospect four or five times over two to three weeks to make sure you get the conversation, and spreading touches across phone, email and in-person visits.
Does cold calling still work for commercial services?
Jarret Ryan, Chief Commercial Officer at Exigent Mechanical Services, considers one opportunity from every 12 cold calls a strong result, and his team's cold-call sprints have reached close to a 30% appointment rate on their best runs.
Should my reps call from their personal cell phones?
It's a trade-off for your team to decide. A number the rep actually owns tends to connect better than a generated one, and one rep on a sales forum put the worry plainly: "My company told me to start using my personal cell phone but I do not want my cell to also turn to spam." Whichever you choose, test the number from a phone you own before a calling block.
