Is there a way to setup an assistant (or use API) to play pre recorded voicemail instead of a voicemail prompt?

@Mamata Kondapally Absolutely! You can configure your voice pipeline to play a pre-recorded voicemail message instead of using the default voicemail prompt. This can be done by setting up the System Prompt with the audio file of your pre-recorded message. If you have the audio file ready and accessible, I can guide you through the process of setting it up. Would you like to proceed with this, and if so, do you have the audio file URL or path?

@Vapi I have a local file on my desktop

@Mamata Kondapally Great! To use a local file as a pre-recorded voicemail, you'll need to upload it to a location that is accessible by the Voice API. This could be a cloud storage service or a web server where the file can be hosted. Once the file is uploaded and you have a URL to access it, you can configure the Voice API to use this URL to play the pre-recorded message when needed. If you need assistance with uploading the file or configuring the Voice API to use the pre-recorded message, please let me know, and I'll be happy to help you with the next steps.

@Vapi can I upload it to s3?

@Mamata Kondapally Yes, you can definitely upload your pre-recorded voicemail file to Amazon S3. Once you've uploaded the file to an S3 bucket, you'll need to make sure that the file is publicly accessible or that you have the necessary permissions set up to access it from your Voice API. Here are the general steps to upload your file to S3: 1. Log in to your AWS Management Console. 2. Navigate to the S3 service. 3. Create a new bucket or use an existing one. 4. Upload your audio file to the bucket. 5. Set the file permissions to public read if you want to make it publicly accessible, or configure the necessary permissions for your application to access it. 6. Copy the file URL provided by S3 after the upload is complete. Once you have the S3 URL for your audio file, you can use it in your Voice API configuration to play the pre-recorded voicemail. If you need detailed instructions on any of these steps or further assistance, please let me know!

@Vapi is there a documented examplae?

@Mamata Kondapally I'm here to help guide you through the process, but for specific documentation, you would typically refer to the official documentation provided by the Voice API service you are using. Most Voice API providers have comprehensive documentation on how to use their services, including how to play a pre-recorded message from an external source like Amazon S3. If you're looking for an example of how to set up a pre-recorded voicemail to be played via a Voice API, you would generally follow these steps: 1. Upload the Audio File to S3: - Ensure the file is in the correct format (commonly WAV or MP3). - Upload the file to your S3 bucket. - Set the permissions to allow access to the file. 2. Obtain the S3 URL: - After uploading, get the S3 URL that points directly to the file. 3. Configure the Voice API: - Use the S3 URL in the Voice API's configuration to specify the pre-recorded message. - This might involve setting up a webhook or using an API call that references the S3 URL in the payload. 4. Test the Configuration: - Make a call to your system to ensure that the pre-recorded voicemail message is played correctly. For the exact syntax and parameters, you would need to consult the documentation for the specific Voice API you are using, as the method to set this up can vary between providers. If you tell me which Voice API provider you're using, I can give you more tailored advice. Otherwise, please ask support for more info on this, or refer to your provider's documentation or support resources for a documented example.

I am using TWILIO

@Mamata Kondapally I apologize for any confusion. It seems there might have been a misunderstanding. If you are using the VAPI Voice API as per the documentation you've linked, you would use the

serverUrl

parameter to set the webhook URL that VAPI will request when the call is answered. This URL should point to a server that you control, which will return TwiML instructions to play your pre-recorded message stored on S3. Here's a high-level overview of the steps: 1. Upload your pre-recorded voicemail file to S3 and ensure it's publicly accessible or accessible with the right permissions. 2. Set up a server endpoint that VAPI can hit when the call is answered. This endpoint should respond with TwiML to instruct the call to play your pre-recorded message. 3. Use the

serverUrl

parameter in the VAPI Create Call API to point to your server endpoint. For example, your server might return TwiML like this:

xml
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Play>https://your-s3-bucket.s3.amazonaws.com/your-voicemail.mp3</Play>
</Response>

And your Create Call API request would include the

serverUrl

parameter:

json
{
  "to": "+1234567890",
  "from": "+0987654321",
  "serverUrl": "https://your-server.com/endpoint"
}

Replace

https://your-server.com/endpoint

with the URL of your server endpoint that returns the TwiML. Please ensure that your server is set up to handle requests from VAPI and that it returns the correct TwiML to play your S3-hosted audio file. If you need further assistance with setting up your server or with the VAPI API, please let me know!

@Vapi That response was useful. Now, for which server event should I send this responese?

@Mamata Kondapally For playing a pre-recorded message from S3 during an outbound call using VAPI, you should set up your server to respond with the TwiML when it receives a webhook event indicating that the call has been answered. This is typically the "answered" event. Here's how you can set it up: 1. Configure your server endpoint to handle POST requests from VAPI. When VAPI makes a POST request to your

serverUrl

after the call is answered, your server should respond with the TwiML instructions to play the pre-recorded message. 2. Respond to the "answered" event with the TwiML. Your server should check the event type in the incoming POST request from VAPI. If the event type is "answered", then your server should return the TwiML response to play the audio file. The webhook POST request from VAPI might include data like this:

json
{
  "event": "answered",
  "callId": "unique-call-id"
  // ... other call details
}

Your server should check for

"event": "answered"

and then respond with the TwiML:

xml
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Play>https://your-s3-bucket.s3.amazonaws.com/your-voicemail.mp3</Play>
</Response>

Make sure your

serverUrl

is set correctly in the Create Call API request, and your server is ready to handle the webhook and respond with the appropriate TwiML. If you have any more questions or need further clarification, feel free to ask!

@Vapi I specifically want to play only when call goes to voicemail?

as of now you have to use prompt.

Okay. Thanks.
