Vapi is the Voice AI platform for developers.

Vapi AI

I'm using the following detection method:

"voicemailDetection": {
        "provider": "twilio",
        "enabled": true,
        "machineDetectionTimeout": 20,
        "machineDetectionSpeechThreshold": 3000,
        "machineDetectionSpeechEndThreshold": 2500,
        "machineDetectionSilenceTimeout": 5000,
        "voicemailDetectionTypes": [
            "machine_end_beep",
            "machine_end_silence"
        ]
    }

But 99% of calls are just hanging there for 2-3 minutes before it hangs up. And then it gets the code that the user hangs up, not that its a voicemail or customer-did-not-pickup.

How can fix this?! This is costing me a couple hundred dollars per day!

We are working on a new model. So, give us some time.
