Dialler

An employee working alone late at night in a dark office

Definition

A dialler calls numbers from a campaign list automatically. A predictive dialler calls more numbers than there are free agents, based on the expected answer rate.

Dialling by hand takes time: type the number, wait, voicemail, next attempt. A dialler takes that work over and connects agents only with people who actually pick up. How much it takes over depends on the dialling mode.

#The risk of predictive mode

A predictive dialler works with probabilities: because only some people answer, it dials more numbers than there are free agents. When the calculation fails, someone picks up and nobody is there.

The result is a silent or abandoned call. It annoys people and looks untrustworthy. A responsible campaign therefore caps the abandon rate, uses progressive mode for small teams and at least plays an announcement when no agent is free.

Before dialling: consent, calling window and suppression list are checked for every attempt. Sample.

The dialling mode does not change the law. In Germany, marketing calls to consumers require prior express consent under section 7 of the Act against Unfair Competition (UWG).

Because campaigns often run for days, checking the list once at import is not enough. A withdrawal received yesterday has to stop today's call.

#Not just for sales

Diallers are not only a sales tool. In service they confirm appointments, announce technician visits or call back after an outage. In collections they make respectful reminders and conversations about payment plans possible.
