Office dialler / auto dialler

Auto dialler or click-to-call? How to choose a dialler for a small sales team

Predictive, power and click-to-call diallers explained, plus why a desk-phone office dialler is rarely the right choice for a small UK outbound team.

"Dialler" covers a lot of ground. It can mean the desk phone on a rep's desk, a piece of software that rings a list automatically, or a button in your browser. If you are choosing one for an outbound team, the differences decide whether your reps spend their day talking or waiting.

The four kinds of dialler

Dialler types compared
TypeHow it worksBest forWatch out for
Office / desk-phone systemReps dial from a physical or softphone handset on the company phone system.Inbound-heavy teams that also make the odd outbound call.Manual dialling, no lead queue, call data trapped in the phone system.
Click-to-callClick a number on screen and the call is placed. One lead at a time, rep-controlled.Small and mid-sized teams calling businesses, where each call is worth preparing for.Quality depends on the queue and logging around the button.
Power diallerAutomatically dials the next lead as soon as the rep finishes the last. One line per rep.High-volume teams working long lists of similar leads.Less time to read about the next person. Can feel relentless.
Predictive diallerDials several numbers per rep at once and connects whoever answers.Large floors on high-volume consumer lists.Abandoned and silent calls when no rep is free. Regulated by Ofcom.

Why predictive dialling is risky for small teams

A predictive dialler works by betting that some of the calls it places will not be answered, so it dials more lines than there are reps. When the bet is wrong and everyone answers at once, someone picks up to silence or a click. In the UK that is regulated: Ofcom limits the proportion of abandoned calls a campaign can produce, and silent calls are treated seriously. Check Ofcom's current guidance before running one. The algorithm needs volume to behave, so with a team of five or ten it tends to produce more of the bad outcome and less of the benefit.

Why not just use the office phone system?

A desk-phone setup is built to route calls, not to run a campaign. It does not know which of your 400 leads is next, who already rang them, or that Sarah asked for a callback at 2pm. Reps end up with the phone system in one window and a spreadsheet in the other, and the outcome of the call is typed up from memory afterwards. That gap is where most of the lost data and missed follow-ups come from. It is the same problem described in cold calling from a spreadsheet.

Why click-to-call with a good queue is usually right

For a team calling businesses, the value of a call is in the preparation and the conversation, not in raw dial volume. A click-to-call dialler that puts the next lead in front of the rep, shows what is known about them, places the call from the browser and logs the outcome in one click removes the dead time without removing the human. There is no abandoned-call risk because a person is on every call before it is placed.

A short checklist

  • Does the rep need hardware, or can they call from a browser?
  • Is there a queue that stops two reps ringing the same lead?
  • Is the outcome logged on the call without retyping?
  • Are do-not-call numbers and calling hours enforced at the moment of dialling?
  • What are the call charges, and are minutes included or billed separately?

Where Dialspire sits

Dialspire is a click-to-call dialler: one lead at a time, placed from the rep's browser with no desk phone, no predictive dialling and no abandoned calls. It adds the queue, row-level locking, one-click outcomes and follow-ups that a phone system lacks. If you need a predictive dialler for a large consumer floor, it is not the right tool, and we would rather say so.

Replace the spreadsheet your team calls off

Import your list, give every rep a live queue, and track every call automatically. No CRM migration.
