# Best power dialers (2026): parallel, power, and what to check before you dial

A power dialer calls your list one number after another so reps stop typing phone numbers. A parallel dialer rings several numbers at once and connects the rep to whoever picks up. For an SDR team doing real call volume, the choice between them decides how many conversations you get per hour and how many people hear a pause before your rep says hello.

Below are the dialers worth a look, grouped by type, with what each vendor publishes about price. Most of the parallel dialers hide pricing behind a demo, so we say that rather than guess. A dialer is only as good as the numbers you feed it, so if your connect rate is low, start with [phone number finder tools](https://getaob.com/phone-number-finder-tools) before you blame the software.

Key takeaways

- Parallel dialers (Nooks, Orum, Koncert, Salesfinity) get the most conversations per hour and cost the most.
- Power dialers (Kixie, PhoneBurner, Aircall, JustCall) dial one line at a time and suit smaller teams or warmer lists.
- Bad mobile numbers kill connect rates faster than any dialer setting. Fix data first.
- Register your numbers for branded caller ID and rotate them, or carriers will label you Spam Likely.
- Calling rules differ by country and state. Check TCPA, DNC, and local consent law with counsel before you scale.

## Power vs parallel vs predictive dialers

A power dialer calls one number per rep at a time and moves to the next one when the call ends. Every connected call already has a rep on the line, so there is no awkward silence. It suits warmer lists, account executives, and teams with good phone data.

A parallel dialer rings several numbers per rep at once (usually three to five) and connects the first human who answers while dropping the rest. Reps get far more conversations per hour on cold lists where most calls go unanswered. The cost is a short delay when the prospect picks up, and some calls get dropped if two people answer at once.

A predictive dialer guesses when an agent will be free and dials ahead across a whole team. It is a call center tool. In the US, predictive dialing to consumers comes with call abandonment limits, so most B2B SDR teams stick to power or parallel.

## Local presence, number rotation, and Spam Likely labels

Local presence shows the prospect a number with their own area code. It can lift answer rates, but carriers watch for numbers that place many short calls, and a number flagged as spam hurts every call after it. Most dialers on this list rotate numbers automatically for that reason.

STIR/SHAKEN is the framework US carriers use to sign calls and confirm the caller ID is real. A good attestation level helps, but it does not stop carrier analytics from labelling you Spam Likely. To fix that, register your numbers with the carrier registries and use branded caller ID so your company name shows on the screen. Ask any vendor which registration and branding services they include before you sign.

- Register every outbound number with your company details before it dials.
- Use branded caller ID where your dialer supports it.
- Cap daily calls per number and rotate numbers rather than burning one.
- Check numbers regularly for spam labels and retire flagged ones.

## Compliance: TCPA, DNC, and consent

This is a summary, not legal advice. Rules depend on who you call, where they are, and whether the number is a mobile, so check the law where your prospects live and talk to counsel before you scale.

In the US, the TCPA restricts autodialed and prerecorded calls and texts, especially to mobile numbers, and the National Do Not Call Registry covers telemarketing to consumers. Calls to business lines are treated more loosely in many cases, but many B2B prospects list a personal mobile, and several states (Florida and Oklahoma among them) have their own stricter telemarketing laws. Outside the US, rules such as GDPR and the UK's PECR apply to cold calls too.

- Scrub lists against the national DNC registry and your own internal do-not-call list.
- Honour opt-outs immediately and log them in your CRM.
- Respect calling hours in the prospect's time zone.
- Be careful with prerecorded voicemail drops and texts to mobiles, which need consent in many cases.
- Keep records of where each phone number came from.

## How to choose a dialer

Start with your connect rate and team size. If reps dial cold lists all day, a parallel dialer usually pays for itself in conversations. If calling is one step in a multichannel sequence, the dialer in your sequencer or a power dialer is often enough.

- Ask for a trial on your own list and count conversations per hour, not dials.
- Check how it syncs to your CRM: call outcome, recording, and notes on the right record.
- Ask about seat minimums and contract length; several vendors require 5 to 10 seats.
- Confirm what number registration, branded caller ID, and DNC tools are included.

## When to get help with a calling motion

The dialer is usually the easy part. The hard part is a list with working mobile numbers, a CRM that records what happened on each call, and a sequence where calls, email, and LinkedIn land in the right order.

OneGTM builds those systems for B2B teams: sourcing and verifying phone data, wiring the dialer into the CRM, and setting up the sequences around it. You own all of it.

- Your reps dial all day and connect rates are under 5%.
- Calls are not landing on the right CRM record, so nobody can see what happened.
- You want to add phone to an email and LinkedIn motion without hiring more SDRs.
- Your numbers keep getting flagged as Spam Likely.

## Power dialers FAQ

### What is the difference between a power dialer and a parallel dialer?

A power dialer calls one number at a time per rep and moves to the next automatically. A parallel dialer calls several numbers at once and connects the rep to the first person who answers. Parallel dialers produce more conversations per hour on cold lists, while power dialers avoid the short connection delay and suit warmer lists.

### What is the best parallel dialer for SDR teams?

Nooks, Orum, and Koncert are the most common choices for dedicated SDR teams, and Salesfinity is a good option if you want a published price. Run a trial on your own list and compare conversations per hour, since results depend heavily on your phone data.

### How much does a power dialer cost?

Published prices range from about $45 per user per month for a dialer add-on like Klenty's to $140 or more for PhoneBurner. Parallel dialers usually cost more: Salesfinity lists $249 per license per month billed annually, and Nooks, Orum, and Koncert quote custom pricing.

### Are power dialers legal?

Power and parallel dialers are widely used, but how you use them matters. In the US, the TCPA, Do Not Call rules, and state telemarketing laws limit autodialed and prerecorded calls, especially to mobile numbers. Rules vary by country and state, so check local law and get legal advice before you scale. This page is not legal advice.

### Why do my calls show up as Spam Likely?

Carrier analytics flag numbers that place many short, unanswered calls. Register your numbers with carrier registries, use branded caller ID, cap daily calls per number, and rotate numbers. STIR/SHAKEN attestation helps confirm your caller ID is real but does not remove spam labels on its own.

### Does local presence dialing still work?

Showing a local area code can still lift answer rates, but it works best with registered, branded numbers that are rotated and not overused. Some prospects now recognise the tactic, so treat it as one input and measure answer rates by number.

### Do I need a dedicated dialer if I use HubSpot or Outreach?

Not always. HubSpot calling and Outreach Voice handle click-to-call, recording, and logging well. Teams whose main job is cold calling usually add a parallel dialer like Nooks or Orum because built-in dialers call one line at a time.
