Choosing a dialler

Quick answer

Pick on suppression handling, per-state calling windows, local presence, call recording and CRM integration before you compare dialling modes. A dialler that cannot read one suppression list, cannot derive calling hours from the merchant’s time zone, and cannot write outcomes back to the CRM will cost you more in compliance exposure and lost data than it saves in connect rate.

Dialler sales conversations are about connect rate. The features that decide whether the tool is any good are further down the page and rarely demonstrated.

RequirementWhy it is non-negotiable
Reads a central suppression list at dial timeThe most common source of claims
Calling windows by the merchant’s time zoneA hard stop, not a warning
Call recording with an announcementLegal in every state, and useful
Two-way CRM syncOutcomes written back, not stranded
Local presence or consistent caller IDConnect rate, without number churn
Attempt history per recordThe only way to measure cadence completion

Dialling modes, briefly

  • Preview — the rep sees the record before it dials. Right for exclusive leads where the call is worth preparing for.
  • Power — one line per rep, dialled automatically. A reasonable middle for a warm feed.
  • Predictive — multiple lines, connects handed to whoever is free. Efficient on volume, and it produces abandoned calls, which carry their own rules.

Number reputation

Carriers label numbers as spam based on how they behave — high volume, short calls, low answer rates. A dialler that rotates through numbers without managing reputation will get your caller IDs flagged, and merchants stop seeing your calls as calls. Ask any vendor specifically how they monitor and remediate spam labelling.

Questions brokers ask

Central suppression checked at dial time, calling windows derived from the merchant’s time zone, call recording with an announcement, two-way CRM sync, caller ID reputation management, and per-record attempt history.

Not on exclusive leads. You paid for a record worth preparing for, and predictive mode drops the rep in with no context while producing abandoned calls that carry their own rules. Preview or power is the right mode.

Because carriers label numbers as spam based on call behaviour, and a flagged number is one merchants never see ring. Ask any dialler vendor how they monitor and remediate labelling.

Yes, as a hard stop derived from the merchant’s time zone rather than a warning a rep can dismiss. It is the single easiest violation for an expanding floor to commit accidentally.

Because cadence completion — the share of leads that got the full sequence before being written off — is the number that explains most apparently underperforming batches, and you cannot calculate it without per-record attempts.
