Outbound Dialing

Progressive Dialer — every answered call has an agent waiting

The progressive dialer dials exactly one lead the moment an agent becomes free. Nobody hears a silent line, nobody gets dropped, and your agents still never touch a keypad — ideal for high-value, compliance-sensitive campaigns.

Why not just use predictive?

Predictive pacing over-dials to keep agents busy — that trades a small abandonment rate for throughput. For collections, premium sales or regulated verticals, even a few dropped or silent calls hurt trust and invite complaints.

Manual dialing fixes that but wastes agent time on ringing, busy tones and wrong numbers. Progressive dialing sits in between: the system does the dialing, but only when a specific agent is ready to take the call.

How It Works

How a progressive dial cycle works

01

Agent goes ready

An agent logs in to the campaign (web or WebRTC softphone) and marks themselves available.

02

One lead is claimed

The engine reserves the agent's line first, then claims the next eligible lead from the assigned lists — so a lead is never dialed without an agent behind it.

03

Connect & screen-pop

On answer the call is bridged straight to the reserved agent with the lead's CRM record, custom fields and history on screen.

04

Disposition & recycle

The agent saves a disposition; retry, callback or DNC rules decide when (or if) the number comes back into the queue.

Features

Built for controlled, high-quality outbound

Line-before-lead claiming

The agent's channel is secured before a number is dialed, eliminating the race where a lead is called but no agent is free.

Multi-list round-robin

Assign several lead lists to one campaign; the dialer rotates between them so no single list is exhausted first.

Retry & alternate numbers

Configurable retries on no-answer/busy, with automatic fallback to a lead's alternate number when one is present.

Daily per-number call cap

A global cap on how many times the same number can be dialed per day protects customers and your caller-ID reputation.

Caller-ID / DID rotation

Map campaigns to DIDs and present the right local caller-ID per trunk, with carrier-level PAI handling.

Live supervisor view

Real-time agent states with ticking idle, wrap-up and break timers, campaign progress and pending-lead counts.

FAQ

Common questions

What is the difference between progressive and predictive dialing?+
Predictive dialing places more calls than there are free agents and relies on statistics to keep abandonment low. Progressive dialing places exactly one call per free agent, so it can never abandon a call — at the cost of slightly lower agent talk-time.
Can one agent work multiple campaigns?+
Yes. Agents can be assigned to several campaigns and lists; the engine respects list assignment and round-robin rules when claiming the next lead.
Can we switch a campaign between preview, progressive and predictive?+
Yes. Dialing mode is a campaign setting, so you can start progressive and move to predictive once list quality and agent count justify it.
Does it detect answering machines?+
Answering-machine detection can be enabled per campaign. In progressive mode many teams leave it off so agents hear the answer directly.
Can we host it on our own servers?+
Yes. The same software runs in the cloud (your account or ours), on-premise in your data centre, or hybrid. Features are identical across deployment modes; on-premise keeps all recordings and lead data inside your network.
