Dialler tools automate the mechanics of cold calling — dialling numbers, logging calls to your CRM, recording for coaching, and in some cases running parallel dials across multiple numbers to cut down time spent listening to voicemail and no-answers. The right tool depends heavily on how many calls per rep per day your team actually makes.
A one- or two-person founder-led sales team making twenty calls a day doesn't need the same tool as an SDR team making two hundred. Buying enterprise parallel-dialling software for low call volume mostly buys you compliance risk and unused seats.
How we judged them
What matters when you're small.
Call volume the tool is built for
Parallel dialling tools that call several numbers at once assume a high-volume team; for lower volume, a straightforward single-line dialler with good CRM logging is more appropriate and cheaper.
CRM integration depth
Check whether call outcomes, notes and recordings sync automatically to your CRM, or if reps have to manually log activity — manual logging quietly kills adoption over time.
Local presence and compliance features
Local caller ID numbers can improve pickup rates, but rules on caller ID and consent vary by country and are getting stricter — check the tool's compliance features match where you're calling.
Call recording and coaching tools
If you're managing a team, look for call recording with easy playback and, ideally, some transcription or coaching flagging rather than just raw audio files.
The picks
What each one is actually good at.
Orum
Custom pricing, typically several hundred dollars a month per seatBest for: High-volume SDR teams wanting AI-assisted parallel dialling
Strong at cutting through voicemail and no-answers with live-conversation detection across multiple simultaneous dials. Priced and built for a dedicated outbound team, not occasional cold calling.
Nooks
Custom pricing, typically enterprise-tierBest for: Teams wanting parallel dialling plus AI coaching features
Similar high-volume dialling to Orum with added AI-driven call coaching and virtual team floor features. Overkill and expensive for a team under a handful of reps.
Aircall
From about $30 a month per seatBest for: Small teams wanting a simple, reliable phone system with a dialler
Easy to set up and reliable for basic calling, recording and CRM logging without the complexity of parallel dialling. Good starting point for a small team that isn't yet at high call volumes.
JustCall
From about $29 a month per seatBest for: Budget-conscious small teams wanting dialler plus SMS
Comparable to Aircall at a similar price point, with SMS built in, which is useful if your sales process mixes calls and texts. Call quality reports vary more than Aircall's.
Kixie
From about $35 a month per seatBest for: Teams already using HubSpot or Pipedrive wanting tight integration
Strong native integrations with popular CRMs and a power dialler for moderate call volumes at a reasonable price. Not built for the very high parallel-dial volumes Orum or Nooks handle.
PhoneBurner
From about $165 a month per seatBest for: Solo reps or small teams wanting a straightforward power dialler
A dependable single-line power dialler with good voicemail drop and list management features. Priced higher than Aircall or JustCall for a narrower feature set focused specifically on dialling.
Skip
What we'd leave alone.
- Parallel dialling tools if your team makes under fifty calls a day per rep — the cost and compliance complexity outweigh the time saved at low volume.
- Any dialler with no CRM integration for a team already using a CRM — manual call logging gets skipped under time pressure and your data goes stale.
- Tools with no clear caller ID or consent compliance documentation, given tightening telemarketing rules in many regions — ask directly before signing a contract.
Questions
Common questions.
What's the difference between a power dialler and a parallel dialler?
A power dialler calls one number at a time but automates dialling and logging between calls, saving manual dial time. A parallel dialler calls several numbers simultaneously and connects the rep only when someone answers, which saves more time but needs enough call volume to justify the added complexity and cost.
Do I need a dialler tool for a small team making a few calls a day?
Probably not a dedicated dialler — a phone system with basic click-to-call and CRM logging, like Aircall on its lower tier, covers low call volumes without paying for automation features you won't use.
Are AI parallel dialers legal?
The tools themselves are legal, but rules around caller ID display, consent, and call recording vary by country and state, and are getting stricter in some regions. Check your specific compliance obligations before scaling call volume, regardless of which tool you use.
Does call recording improve sales performance?
It's mainly useful for coaching — reviewing real calls with reps to fix specific habits tends to help more than the recording itself. A tool with easy playback and searchable transcripts gets used for coaching far more than one where recordings are hard to find.
