drop_action
What Drop Action Does
Defines what happens when an outbound call is answered but no agent is available to take it (an abandoned call). Options include playing a safe harbor message (MESSAGE), routing to an inbound queue (IN_GROUP), or hanging up (HANGUP). Regulatory compliance may require a specific action.
Recommended Configuration
| Center Size | Recommended Value | Notes |
| --- | --- | --- |
| 10–25 Agents | MESSAGE for compliance, HANGUP for efficiency | Start conservative, monitor for 48 hours before adjusting |
| 25–100 Agents | MESSAGE for compliance, HANGUP for efficiency | Scale gradually — larger operations amplify effects of misconfiguration |
| 100–500 Agents | MESSAGE for compliance, HANGUP for efficiency | Consult ViciStack optimization team for enterprise-scale tuning |

IN_GROUP requires a valid inbound group with agent coverage
ViciStack Module
ViciStack’s Dialer Tuning & Auto-Configuration module automatically monitors and optimizes drop_action based on real-time performance data from your operation. Instead of manual tuning, ViciStack continuously analyzes call outcomes, agent performance, and contact rates to recommend and implement optimal values — often catching configuration drift before it affects your numbers.
