What Auto Alternate Dial Does

Configures VICIdial to automatically dial alternate phone numbers stored in lead records when the primary number results in specific dispositions (busy, no answer, disconnected). Options include dialing alternate numbers in the same call attempt or scheduling them for future attempts.

| Center Size | Recommended Value | Notes |

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

| 10–25 Agents | ALT_ONLY or ADDR3_ONLY depending on data | Start conservative, monitor for 48 hours before adjusting |

| 25–100 Agents | ALT_ONLY or ADDR3_ONLY depending on data | Scale gradually — larger operations amplify effects of misconfiguration |

| 100–500 Agents | ALT_ONLY or ADDR3_ONLY depending on data | Consult ViciStack optimization team for enterprise-scale tuning |
