A power dialer is simply the fastest way to increase the number of meaningful conversations your sales team has every day. Instead of manually dialing, waiting for voicemail, and logging calls, a power dialer automates the process: your salesperson picks up when a human answers, skips voicemail, and moves straight on to the next number.
The result: most teams see a 2–4× increase in contact rate within the first week. We spent three months testing 10 of the most popular tools. Here's what we found.
What is a power dialer?
A power dialer automatically calls through a list of numbers and connects your salesperson only when a real person answers the phone. Key features to look for:
- Automatic voicemail drop: leave a pre-recorded message instantly and move on
- Local presence dialing: call from a local area code to boost answer rates by up to 40%
- CRM integration: log calls, update records, and trigger workflows automatically
- AI call recording and transcription: review every call without taking notes
- Real-time coaching: managers can listen in and whisper to salespeople mid-call
The 10 tools compared
1. Klientel Power Dialer
Built directly into Klientel CRM, this is the only solution on the list requiring no integration at all. Call directly from a contact record, drop voicemail, get AI call summaries, and advance deals: all on one screen. Best for teams that want everything in one place.
2. Salesloft Dialer
Strong cadence management and excellent Salesforce integration. The interface is polished, but the dialer sits inside a larger platform you may not need. Pricing starts high for small teams.
3. Outreach Voice
Robust sequence automation paired with calling. AI-driven sentiment analysis flags calls worth reviewing. Overkill for teams under 10 salespeople, and the learning curve is steep.
4. Aircall
Cloud phone system with power dialing. Strong for customer support teams that also make outbound calls. Integrates with 100+ tools, but lacks native CRM pipeline features.
5. JustCall
Affordable and easy to implement. Good for SMBs that need basic auto-dialing and SMS without a complex setup. Limited AI features compared to newer players.
6. PhoneBurner
One of the original power dialers. Excellent speed: no lag when a call connects. Lacks the modern AI-coaching features of newer tools, but is highly reliable.
7. Orum
AI-first dialer that uses ML to predict the best time to call each contact. Impressive contact rates. Pricing is enterprise-focused and not published.
8. Nooks
Parallel dialer (not a power dialer): calls multiple numbers simultaneously and connects the first answer. Dramatically increases volume, but requires careful compliance oversight.
9. ConnectAndSell
Human-assisted dialing: agents navigate phone menus on your behalf and transfer you when a decision-maker answers. Extremely high contact rates, but expensive and an unusual workflow.
10. Kixie
Simple power dialer with strong HubSpot integration. One of the easiest to set up. A good choice for teams already invested in the HubSpot ecosystem.
Key features to evaluate
- CRM sync: does it log automatically, or does it require manual entry?
- Voicemail drop quality: some drop generic messages; the best ones personalize them
- Compliance tools: TCPA compliance, DNC list management, call-recording consent
- Call quality: VoIP latency determines first impressions
- Reporting: contact rate, talk time, calls per salesperson per hour: can you see these?

Our recommendation
If you're a team of 1–50 salespeople looking for a complete sales platform without stitching together multiple tools, Klientel is the clear winner: the dialer, CRM, pipeline, AI coaching, and automation are all native. For teams deeply entrenched in Salesforce, Salesloft is worth the investment. For budget-conscious SMBs, JustCall gets the job done.
Whichever tool you choose, the most important factor is actually using it. A power dialer at 30% utilization delivers 30% of its potential. Track calls per salesperson per day and hold your team accountable for the number.
