Is there any option to take the caller voice mail or call back something when inbound call assistant not able to pick or answer the call

Yes, Vapi offers voicemail detection as a fallback option when an inbound assistant is unavailable. You can configure this in your assistant settings with the following JSON:

json
"voicemailDetection": {
  "provider": "twilio",
  "voicemailDetectionTypes": ["machine_end_beep", "human"],
  "enabled": true,
  "machineDetectionTimeout": 45
}

This allows your assistant to detect voicemail and either hang up or play a custom message when the inbound assistant can't answer.

Vapi doesn’t have builtin voicemail, but you can set a fallback to play a message, schedule a callback, or return to the AI if no one answers, and you can use Twilio to record voicemails if needed..

Hello @Kings_big💫 How Can I do that ?
