A campaign's dial mode decides who initiates each call and how far ahead of agent availability the dialer works. Choosing wrong produces either idle agents or abandoned calls, so this is the first decision on any new campaign. ## How it works Get2Dial has five dial modes: | Mode | Who initiates the call | Behavior | | ----------------------------- | ---------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Preview** | The agent | The agent reviews a lead's details and confirms before the call is placed. | | **Progressive** | The system | Places one call per available agent, only once an agent is free. | | **Power** | The system | Dials ahead of agent availability at a set ratio (the overdial ratio) — more lines open than agents free. | | **Predictive** | The system | Uses recent connect-rate data to predict how many calls to place so an agent is free right as one connects, subject to an abandonment-rate cap. | | **Press-1 (voice broadcast)** | The system | Dials a lead, plays a recorded message on answer, and transfers them to a queue only if they press a configured digit. No agent is consumed unless the lead presses. | ## When to use it | If you need... | Use | | --------------------------------------------------------------------------------------------------------------------------- | ----------------------------- | | An agent to see who they're calling before it dials — high-touch, compliance-sensitive, or complex sales | **Preview** | | Zero idle time risk and one call per agent, no overdial | **Progressive** | | Higher throughput than progressive, with a controlled, fixed overdial ratio | **Power** | | Maximum agent utilization on large lists with a predictable connect rate | **Predictive** | | A one-way announcement that only reaches an agent when the recipient opts in by keypress — notifications, alerts, reminders | **Press-1 (voice broadcast)** | There is no "manual" mode — every non-broadcast mode either has the agent explicitly confirm each call (preview) or has the system dial automatically (progressive, power, predictive). ## What it affects Power and predictive modes dial ahead of agent availability, which means some connected calls will have no agent free — those calls are abandoned. Get2Dial enforces an **abandonment rate cap** (see [How the dialer paces calls](/outbound/how-pacing-works)) so this stays bounded, but a higher-throughput mode always carries more abandon risk than preview or progressive. Abandoned calls carry real compliance exposure in many jurisdictions — see [Compliance and trust](/compliance/dnc-lists). Press-1 paces against the agents available in its **target queue** specifically, not the campaign's own connect queue — see [Configure a press-1 campaign](/outbound/campaigns/press1-broadcasts). A lead who never presses the digit is never counted as abandoned in the agent-facing sense; they finish the message and the call ends. ## Limits and constraints Dial mode is set per campaign and can be changed at any time, including while the campaign is running. A press-1 campaign additionally can't reach status **Running** unless its broadcast audio, transfer digit, and target queue all still resolve — see [Configure a press-1 campaign](/outbound/campaigns/press1-broadcasts). ## Next steps
