What Auto Dial Level Does

Sets the number of simultaneous outbound call attempts per available agent. A value of 1.0 means one call per agent; 2.0 means two simultaneous dials per agent. Higher values increase contact rate but also increase abandoned call risk. This is the primary dial performance lever in VICIdial.

Center Size Recommended Value Notes
10–25 Agents 1.5 to 3.5 for most outbound campaigns Start conservative, monitor for 48 hours before adjusting
25–100 Agents 1.5 to 3.5 for most outbound campaigns Scale gradually — larger operations amplify effects of misconfiguration
100–500 Agents 1.5 to 3.5 for most outbound campaigns Consult ViciStack optimization team for enterprise-scale tuning

Common Problems

Setting too high causes abandon rate violations and TCPA risk

Setting too low wastes agent capacity — agents sit idle waiting for calls

Not using adaptive mode means the level never adjusts to traffic conditions

ViciStack Module

How ViciStack Optimizes Auto Dial Level

ViciStack's Dialer Tuning & Auto-Configuration module automatically monitors and optimizes auto_dial_level 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.
