Changes to Predictive Dialer
JustCall's Predictive Dialer has evolved significantly from its original version. If you used the legacy Predictive Dialer, this article explains what changed, how the current version works, and how it compares to Power Dialer and Dynamic Dialer.
What the legacy Predictive Dialer did
The original Predictive Dialer automatically called multiple numbers simultaneously and connected answered calls to available agents. It used an algorithm to predict agent availability and dialed ahead to minimize idle time between conversations.
What changed
The current Predictive Dialer includes several updates from the legacy version:
| Area | Legacy behavior | Current behavior |
|---|---|---|
| Dialing ratio | Fixed ratio set by admin | Dynamic ratio that adjusts automatically based on answer rates and agent availability |
| Voicemail detection | Basic detection, higher false-positive rate | Improved AI-powered answering machine detection (AMD) |
| Compliance | Manual pacing controls | Built-in abandon rate limits to comply with TCPA and FTC regulations |
| Reporting | Basic call logs | Detailed campaign analytics with connect rate, talk time, and disposition breakdowns |
| CRM integration | Limited sync | Full CRM sync with automatic contact updates and activity logging |
Predictive vs Power vs Dynamic Dialer
JustCall offers three dialer modes. Choose based on your team's workflow:
| Dialer | How it works | Best for |
|---|---|---|
| Predictive | Dials multiple numbers simultaneously, connects answered calls to agents | Large teams running high-volume outbound campaigns |
| Power | Dials numbers one at a time automatically from a list, connecting each answered call to the agent | Individual reps or small teams who want speed without overlap |
| Dynamic | Adjusts dialing behavior in real time based on campaign performance | Teams that want automation without manual tuning |
Migration notes
If you were using the legacy Predictive Dialer and your settings were migrated:
- Your contact lists and campaign history are preserved
- Dialing ratio settings were reset to automatic — review and adjust under Sales Dialer > Campaign Settings if needed
- Voicemail detection defaults to the new AI-powered mode
- Any custom pacing rules from the legacy version need to be reconfigured in the current interface
If your campaigns behave differently after migration, check the dialing ratio and AMD settings first. These are the most common areas that need adjustment.
