Choosing cold calling software looks like an easy purchase. You open three tabs, compare pricing grids, and pick the one with the nicest demo. Six months later, the team still spends just as much time waiting for the phone to ring, and the CRM is no better filled in than before.
The problem is rarely the tool itself. It is that you compared products that do different jobs. Here is how I advise sales teams to go about it when they ask us for help, including when the right answer is not Flunter.
Three kinds of tools under the same name
Search for "cold calling software" and you land on very different products.
The first kind is the cloud phone system: Aircall, Ringover, CloudTalk, Allo. These are modern phone systems. They handle numbers, inbound calls, queues and transfers between colleagues. They can place outbound calls too, one at a time, by clicking a number.
The second is the power dialer. You load a list and the tool dials the next number as soon as you hang up. No typing, no dead time between calls. The rep is still on one line at a time.
The third is the parallel dialer. It dials several numbers at once and connects you to the first person who picks up. That is what our parallel dialer does, with up to five simultaneous lines.
These three kinds solve different problems. If you mostly handle inbound calls and prospecting is a side activity, a cloud phone system is enough. If your reps spend several hours a day calling lists, you need a dialer. For the details, we wrote a comparison of parallel, power and predictive dialers.
To compare the tools one by one, with their prices, strengths and limits, see our comparison of 46 cold calling tools.
Start from your bottleneck, not from a feature list
Before you open a single vendor website, take a typical day for one of your reps and break it down. How long do they spend finding the number, dialing it, waiting, hitting voicemail, filling in the CRM after the call? And how many minutes of real conversation at the end?
With the teams we work with, the same picture comes up again and again: conversation is a small share of the time spent "on the phone". The rest is waiting and admin.
The right software is the one that tackles your biggest loss. If it is manual dialing, a power dialer already fixes a lot. If it is waiting on numbers that never answer, only a parallel dialer really changes things, because it rings several lines while you wait for one person. If it is logging after the call, look closely at the CRM integration and automatic summaries.
And if your problem is a list full of switchboards and wrong numbers, no tool will save you. Start there. We cover it in detail in our article on cold calling pickup rate.
The criteria that matter day to day
Feature grids all look alike. The differences show up elsewhere, in details you only notice after a few days of use.
Caller ID. A local, stable number the prospect can call back. Ask how the vendor handles number authentication with carriers, and what happens when a number gets flagged.
Voicemail detection. On a dialer, it decides whether you lose ten seconds or a full minute on every answering machine.
Connection delay. When someone picks up, how long before they hear you? Past one second, many hang up thinking it is a robot.
CRM integration. Not just "works with HubSpot", but: do calls land on the right record, with the recording and the note, without the rep doing anything?
Reporting. You need pickup rate and conversations per rep and per list, or you are flying blind.
Audio quality cannot be judged in a demo. You judge it on a Tuesday at 10am, on the office wifi, with someone calling from a train.
What the list price does not tell you
Two tools with the same list price can cost twice as much once in production. It all depends on what you are billed for.
Some vendors bill per minute, others per connected call, others per simultaneous line. A parallel dialer that rings five numbers at once burns a lot of outbound minutes for a single conversation: on a per-minute plan, the bill climbs fast. Flunter's plans include a monthly volume of call credits (one credit per call placed), with no per-minute billing, precisely to avoid that. Details are on the pricing page.
Ask these questions before signing, too. Is there an annual commitment? Are phone numbers included? Is your CRM integration in the base plan or only in the higher tier? How much does an extra user cost mid-year?
A two-week trial that actually answers the question
Most free trials are useless because they are run badly. One rep tests the tool between two meetings, on a demo list, and the decision comes down to a feeling.
Here is a more reliable protocol. Take two reps, a real list you would have called anyway, and block fixed calling slots. In week one, they call with your current setup. In week two, with the tool you are testing, on the same kind of list and the same slots.
Then compare three numbers: conversations per calling hour, pickup rate and meetings booked. Ignore calls made. It is the number that flatters every dialer and tells you nothing about sales.
During the trial, also ask the reps what annoyed them. A tool the team hates always ends up bypassed, however good it looks on paper.
The mistakes I see most often
The first is buying for a future team. You take the plan with every option because you plan to hire six SDRs, and you pay for empty seats for a year.
The second is plugging a parallel dialer into a list of 300 contacts. With five simultaneous lines, the list is gone in one morning. This kind of tool is built for volume: several hundred calls a day per rep.
The third is forgetting the pitch. With a dialer, the prospect picks up and you are live almost instantly. No time to reread their record. The first seconds must be ready, tested and adapted to each segment. Our guide to cold call scripts can help you build them.
The last is measuring nothing before switching tools. Without a baseline, you cannot tell whether the new tool improved anything.
Frequently asked questions
There is no single answer. For a team that mostly handles inbound, a cloud phone system like Aircall or Ringover does the job well. For a team making high outbound volume, a parallel dialer will deliver more conversations per hour. Our comparison of French parallel dialers reviews the options available in France.
Expect a few dozen euros per user per month for an entry-level cloud phone system, up to more than a hundred euros for a dialer with included volume. At Flunter, the entry plan is €89 excl. VAT per month, or €67 billed annually.
No. It plugs into it. The CRM remains the home of your contacts and pipeline, and the calling software writes the history, recordings and notes into it automatically. Check the list of available integrations before choosing.
No, but each rep needs their own seat and, ideally, their own caller ID. That way the prospect calls back the right person and you can track individual results.
What you can do on Monday
Take one calling hour from one of your reps and write down, minute by minute, where the time goes. That exercise alone tells you which kind of tool to look at, and saves you half the pointless demos.
If waiting and dialing dominate, you can try Flunter for free on one of your lists, or book a demo so we can look together at whether a parallel dialer makes sense for your team.
