Is there other prompts or tools needed for the voice assistant to successfully identify & hang-up voicemail calls. I've tried the Twilio AMD and it's worse & more costly. The Vapi built-in still interacts with Voicemails. Are there any other settings or things to add to the prompt to have it successfully hang up? Each voicemail interaction is costing me $0.03 - $0.05 c94d8305-aa11-4a6f-9612-e1a7e0301af3 56429679-b742-4b69-b39b-c55c097e1fa5 4859615a-9b17-4ac8-85d8-c933603608bc But when it successfully identifies like these examples, it cost me $0.01 070507a4-7abf-4c42-90a3-e336e2dd66c0 a3a3a212-74dc-461d-a68f-9d1106c29f06 a50a4a54-b0d9-40ca-90fd-1ae8195de388 Here's the voicemail part of my code "tools": [ { "type": "voicemail" }, { "type": "endCall" }

- enable the twilio voicemail

voicemailDetection: {
  provider: "twilio",
  voicemailDetectionTypes: [
    "machine_start",
    "machine_end_beep",
    "machine_end_silence",
    "unknown",
    "machine_end_other"
  ],
  enabled: true,
  machineDetectionTimeout: 15,
  machineDetectionSpeechThreshold: 2500,
  machineDetectionSpeechEndThreshold: 2050,
  machineDetectionSilenceTimeout: 2000
}

- set the

waitSeconds

to 0.8

"startSpeakingPlan": {
        "waitSeconds": 0.8
      }
