09/30/2025, 1:08 PMfirstMessageMode to "assistant-waits-for-user" in your assistant configuration. This instructs the assistant to wait for the user to say something before delivering the first message:
json
{
"firstMessageMode": "assistant-waits-for-user"
}
This may help prevent the assistant from speaking during ringing, though full answer detection on outbound calls is not explicitly documented as supported. For more details, see the [Vapi documentation](https://docs.vapi.ai/assistants/quickstart).

10/08/2025, 10:38 PManswerOnBridge=true. This prevents Twilio from sending media until the call is answered.
3. Optional delay
- If needed, you can add a short (1–2s) buffer in Vapi before the bot speaks, to cover cases where the answer signal is slightly delayed.

Summary:
The issue isn’t with Vapi’s timing, but with when the call is being bridged. Adjusting your Vici/Twilio settings to wait for answer will ensure the bot only speaks once the customer actually picks up.
