start_call_url

What Start Call URL Does

A URL that VICIdial calls via HTTP GET when a call connects to an agent. Used to trigger CRM screen pops, log call events, or integrate with external systems. Supports VICIdial variable substitution to pass lead data, call ID, and agent information to the target URL.

Recommended Configuration

| Center Size | Recommended Value | Notes |

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

| 10–25 Agents | Configure for CRM integration | Start conservative, monitor for 48 hours before adjusting |

| 25–100 Agents | Configure for CRM integration | Scale gradually — larger operations amplify effects of misconfiguration |

| 100–500 Agents | Configure for CRM integration | Consult ViciStack optimization team for enterprise-scale tuning |

How to Change This Setting

• Navigate to Admin > Campaigns

• Select campaign

• Find Start Call URL field

• Enter target URL with VICIdial variable placeholders (e.g., —A—lead_id—B—)

• Test URL manually with sample values first

• Verify target URL responds quickly (under 500ms) to avoid call delay

• Submit

Common Problems

Slow external URL causes agent screen pop delay of several seconds

URL errors don’t prevent call delivery but cause silent CRM sync failures

Variable substitution syntax must match VICIdial documentation exactly

ViciStack Module

ViciStack’s List Management & Optimization module automatically monitors and optimizes start_call_url 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.
