The workhorse of inside sales.
One line per agent, queue-driven, auto-advancing. If you've ever heard the words "click-to-dial"on a sales floor, you've heard the power dialer. It's the mode that defined outbound from 1995 onward and still does the majority of the work in B2B and SDR shops.
How power dialing works
Power is preview's faster sibling. The agent still triggers the run, but once started the system stops asking permission between calls. You click once, it dials forever — or until you stop it.
- Set yourself available, pick a campaign, click Initiate Dial Sequence.
- The system pulls the next lead from the queue and immediately places the call. The lead profile appears on your screen as the phone rings.
- Phone rings. You wait. If a human answers, you talk. If voicemail or no-answer, the system can drop the call and move on (or pop disposition first, depending on settings).
- After hangup or disposition, the queue advances. The next lead pulls automatically. No clicking required.
- Loop forever, or until you set yourself offline.
Where it came from
The power dialer is a 1990s invention. Through the 1980s, big call centers had been running predictive systems (more on those later), but predictive required serious hardware — Aspect CallCenter, Rockwell Spectrum, EIS dialers — and serious compliance discipline. Smaller shops couldn't afford either.
What smaller shops couldafford, by the mid-1990s, was a PC running early CRM software (ACT!, GoldMine, Maximizer) with a TAPI or modem dial-out integration. Click a contact in the CRM, the modem dials the number, the agent picks up the handset. That was the seed. It got formalized as "click-to-dial" by Avaya and similar vendors and quickly evolved into queue-driven workflows — the system wouldn't just dial when clicked, it would auto-pull from a list.
The term "power dialer" came from the marketing departments of vendors trying to differentiate this faster mode from manual without claiming it was predictive. Mojo Dialer (founded 2001, with VoIP from around 2008) and PhoneBurner (2008) brought it down-market to solo agents and small teams in the 2010s. By then, predictive had become a big-shop tool and power had become the default for everyone else.
The mode hasn't fundamentally changed in 25 years. What changed around it is everything else: lead lists in cloud CRMs, dialer audio over WebRTC instead of a desk phone, and answering-machine detection (AMD) that's good enough to meaningfully cut wasted time on voicemails.
When power wins
Power is the right default for most outbound. It's faster than preview, safer than predictive, and works with a team of one.
SDR TEAMS
Inside sales reps qualifying leads. You need volume, you need to read the lead while it rings, you don't need predictive pacing.
SOLO AGENTS
Predictive needs multiple agents to make sense. Power is the most efficient mode you can run alone.
B2B COLD CALLING
Calling businesses with mid-quality lists. You want speed without dropping calls — power handles that.
WARM B2C FOLLOW-UPS
Leads opted in, you have context, you don't need predictive throughput. Power keeps it personal but fast.
SMALL TEAMS (2-4)
Below the threshold where predictive math actually pays off, but above where preview is too slow. Power is the sweet spot.
COMPLIANCE-SENSITIVE LISTS
Zero abandonment risk by design — one line per agent. You stay 100% within FTC and TCPA rules without thinking about it.
What you give up
The dead time during ring. A power agent spends real seconds waiting on each ring. On a list with a 25% pickup rate, three out of four dials are time you'll never get back. Add a few seconds per disposition, and your effective talk time floats around 15–20 minutes per hour.
The other thing power gives up is voicemail filtering — by default. If you're hitting answering machines on every third dial and you don't turn AMD on, you're going to hear the same robotic "Hi, you've reached ..." ten thousand times before the year is out. It's a one-click toggle in campaign settings if you'd rather have progressive's filtering behavior on a power-mode campaign.
Power on DialerSeat
Power is the default mode for new campaigns. Pick it and you're dialing — no per-campaign tuning required.
- AMD is off by default in power mode — you hear every pickup, voicemail included. Flip it on per-campaign in settings if you want machine pickups filtered out.
- Auto-advance after disposition — no clicking between calls once you're going.
- One outbound line per agent. Zero abandonment possible. No FTC exposure.
- TCPA window enforcement per lead's local time zone. No 6 AM Pacific dials to East Coast leads.
- National DNC scrubbing is on you — scrub your list against the registry before you upload it. State-specific lists are on you too. See how we keep compliance.
- Keyboard shortcuts for disposition so you keep your hands on the keys, not the mouse.
- Live duration timer, connected-rate counter, and per-session metrics in the right sidebar.
The other three modes
Agent reviews, then dials
The original outbound mode. Slow by design — right for high-touch, high-value calls.
PROGRESSIVEAuto-dial with voicemail filtering
Same compliance profile as power, but the system listens to the pickup and drops machines.
PREDICTIVEMultiple lines, agent prediction
1.5–3× lines per agent. Highest throughput, needs a team of 8+ to really engage, auto-degrade keeps it off the legal line.
