Predictive auto-dialing is live in Mariacall

Mariacall just shipped predictive auto-dialing, the missing piece that turns outbound teams from receptionists with a list into operators with a system. If you run a sales floor, a debt-collection desk, a research call programme or any kind of campaign that involves dialling a list, this is the one feature that changes the math.

What "predictive" actually means

A regular dialer rings one number at a time. An agent waits. Most calls don't connect — busy, voicemail, dead line, declined. The agent listens to silence, then dials again. On a clean B2C list, agents spend more time waiting than talking.

A predictive dialer changes the loop. It rings several numbers at once, watches in real time which ones connect, and routes only the answered calls to the next available agent. The unanswered, busy and voicemail attempts are dropped or queued by the system, never by a human.

Done well, an agent goes from ~12 conversations an hour to 30–40, with no extra effort and no extra stress.

What we built

Three things, working together:

• Pacing engine. Mariacall now computes a live call-to-answer ratio per campaign and adjusts how aggressively it dials. The pacing is conservative by default — the system would rather hold a call back than abandon one.
• Answering-machine detection. Voicemail systems get dropped automatically (and optionally logged for a callback later). Real humans get the agent.
• Agent-ready routing. When a call is answered, Mariacall connects it to the agent whose status is "ready" — not to whoever happens to be free in the next 800 ms. If no agent is ready, the call is held with hold music for up to a configurable window, then released.

Under the hood, the engine runs on SIP trunks you already configured for inbound — no separate provisioning, no new carrier contract.

What it means for you

A few things change immediately the day you switch:

• Idle time drops by 40–60%. Agents stop dialling. They talk.
• Talk-time per shift goes up by a multiple. The list moves much faster, and you finish the day having actually called the people who needed calling.
• Compliance gets easier. Predictive dialing is regulated in several markets — Mariacall's pacing engine respects a configurable abandonment-rate ceiling (set it to 3% by default to stay compliant with most jurisdictions). The system logs the rate, so the compliance officer can verify it later.
• Agent burnout drops. This sounds counter-intuitive — more calls per hour, less burnout? — but agents tell us it's true. The repetitive part of the job (dialling) goes away. The interesting part (the conversation) stays.

Switching a campaign over

In the Mariacall console:

1. Open your campaign. 2. Switch dialing mode from Manual or Preview to Predictive. 3. Set the abandonment-rate ceiling. 3% is the safe default; 5% is the regulatory cap in most jurisdictions. 4. Pick how aggressive the answering-machine detection should be: Fast (snappier connects, occasional false positives), Balanced (default), or Conservative (never drops a real human, slightly more voicemail-to-agent leaks). 5. Save. Next time the campaign runs, predictive pacing is on.

There's no migration step. Lists, agents, scripts, reports — all the same.

Who should and shouldn't switch

Predictive is the right default for outbound campaigns with clean B2C lists, repeatable scripts and a team of three or more agents working the campaign simultaneously. If you only have one agent, or you're calling cold C-suite contacts where you want the agent to research each prospect before dialing, stay on Preview mode.

What's next

We're shipping campaign-level real-time dashboards next — live abandonment rate, live talk-time-per-agent, list-burn-rate forecast — so supervisors can spot a bad list or a drifting pacing setting before the shift ends. That's in the next release, mid-June.
