02/03/2026, 3:59 PMassistant-request event is emitted, remove any fixed assistant assignment from your phone number's inbound settings in the Vapi dashboard. This allows Vapi to trigger your Server URL and request the assistant dynamically.
Example:
1. Go to your phone number settings.
2. Set the "Assistant" dropdown to empty or none.
3. Save changes and test your webhook.
This should enable the event as described in the [documentation](https://docs.vapi.ai/server-url/spam-call-rejection).
