call_timeout

What Call Timeout Does

The maximum number of seconds VICIdial will let an outbound call ring before hanging up and marking the lead as a No Answer (NA). Setting this too high wastes agent-attached time on unanswered calls; too low misses contacts who need extra rings to answer.

Recommended Configuration

| Center Size | Recommended Value | Notes |

| --- | --- | --- |

| 10–25 Agents | 20 to 30 seconds | Start conservative, monitor for 48 hours before adjusting |

| 25–100 Agents | 20 to 30 seconds | Scale gradually — larger operations amplify effects of misconfiguration |

| 100–500 Agents | 20 to 30 seconds | Consult ViciStack optimization team for enterprise-scale tuning |

How to Change This Setting

• Go to Admin > Campaigns

• Select campaign

• Find Call Timeout field

• Enter seconds as integer (e.g., 25)

• Consider local ring patterns — US landlines ring ~6 seconds per cycle

• 4-5 rings = 24-30 seconds is industry standard

• Submit changes

Common Problems

Values above 40 seconds dramatically reduce dials-per-hour

Values below 15 seconds miss genuine contacts on mobile phones

Must align with dial_timeout which controls Asterisk-level timeout

ViciStack Module

ViciStack’s Dialer Tuning & Auto-Configuration module automatically monitors and optimizes call_timeout 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.
