Voicemail now not working again...
# support
t
Hello again! I am having voicemail issues, once again.... Here is my request to leave a voicemail, which seems to be working fine... other than it's not hanging up:
Copy code
"voicemailDetection": {
            "provider": "twilio",
            "voicemailDetectionTypes": [
              "machine_end_beep",
              "machine_end_silence",
              "unknown",
              "machine_end_other"
            ],
            "enabled": info.info.agent.voicemail,
            "machineDetectionTimeout": 45,
            "machineDetectionSpeechThreshold": 2400,
            "machineDetectionSpeechEndThreshold": 2400,
            "machineDetectionSilenceTimeout": 6000
          },
          "voicemailMessage": info.info.agent.voicemail_message,

          "model": {
            "provider": "openai",
            "model": "gpt-4o-mini",
            "maxTokens": 250,
            "temperature": 0.3,
            "numFastTurns": 0,
            "semanticCachingEnabled": false,
            "emotionRecognitionEnabled": false,
            "tools": [{ type: "voicemail" }],
Copy code
"startSpeakingPlan": {
            "waitSeconds": 0.8,
            "smartEndpointingEnabled": true,
            "customEndpointingRules": [
              {
                "type": "assistant",
                "regex": ".*" + info.info.agent.voicemail_message + ".*",
                "timeoutSeconds": 3
              }
            ]
          }
Call IDs: 7be128e6-2301-4c48-a852-31b1b727eeee bc456f6a-dad6-4984-a9f8-0396dfaf2020 In my request, when I don't want to leave a voicemail, I am just removing the voicemail detection parts.
When I pulled up the call ID's in the API logs portion of the Dashboard, I don't even see the voicemail detection as part of my request... which I find odd, as all of this was working fine.

Hi there! I see you're having issues with voicemail not hanging up. Looking at your configuration, I've identified a few potential issues that might be causing this problem: 1. **Speech End Threshold Setting**: Your 
machineDetectionSpeechEndThreshold
is set to 2400ms, which is higher than the recommended range of 1000-2050ms. This might be preventing proper detection of when speech ends in the voicemail greeting. 2. **Smart Endpointing**: You have 
smartEndpointingEnabled: true
which could potentially interfere with the voicemail detection process. 3. **Custom Endpointing Rules**: Your custom rules might be affecting how the system handles voicemail detection. Here are some recommended adjustments:
Copy code
json
"machineDetectionSpeechEndThreshold": 1200,
"smartEndpointingEnabled": false
Also, consider these additional troubleshooting steps: 1. **Increase Detection Timeout**: Your current timeout of 45 seconds should be sufficient, but you might want to verify it's not too long. 2. **Verify Detection Types**: Your detection types look good, but ensure they're all supported by Twilio. 3. **Check Logs**: Review the logs for the specific call IDs you provided to see if there are any error messages or warnings. 4. **Test Different Configurations**: Try removing the custom endpointing rules temporarily to see if that resolves the issue. Let me know if these adjustments help or if you need further assistance! đŸ™‚ Sources: - [Discord message about voicemail detection configuration](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1342555558984814653) - [Vapi documentation on phone calling/voice mail detection](https://docs.vapi.ai/phone-calling/voice-mail-detection) - [Discord message about voicemail detection issues](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334385998423130174)

These settings were working prior...
I've attached my complete code with the requests, obviously the lines with // are commented out, just incase you wanted to see the WHOLE request I am sending.
Is there a proper way to handle voicemail now?
I can obviously change my requests based on the proper way to do it.

Hey Trent, give me some time to look into this. I won't forget about you.
t
Sweet thanks
j
@Trentâ„¢ have you tried the new google gemini voicemail detection ?
t
nope
Didn't know that was an option, is it any good? @Jeebs from eva.be

@Trentâ„¢ I read this in their latest email. I've tried it but don't really know how it's supposed to work, couldn't have it working for now https://cdn.discordapp.com/attachments/1349180292803592284/1349373106178752604/image.png?ex=67d2dd22&is=67d18ba2&hm=f84753d9ac83d69e5e6b85e6d3aec90eaeeff9eaeaa8a7386503887d311cdcdd&
t
interesting
j
Would love to get more explanation somewhere but couldn't find any
t
that seems like the ongoing thing for the documentation on here lol

Hey Trent, Twilio voicemail detection can be unreliable. Please try switching to Gemini's voicemail detection in your assistant settings and test it out.
t
how can I turn on gemini's voicemail detection if I'm using api requests?
@Mason

Hey Trent, You can set your voicemail detection provider by making a patch request to the update assistant endpoint. Here is the field you'll be adjusting:
