@Eddie I'm here to help you with that! To transfer a call with a specific message, you'll need to ensure that your Voice API is set up to play a message before executing the transfer. This usually involves using a method to play an audio message or a text-to-speech message, followed by the call transfer method. The exact API call structure will depend on the Voice API you're using, but generally, you would need to: 1. Use a method to play the message (e.g., 
playAudio
or 
speak
with text-to-speech). 2. After the message is played, use the 
transferCall
function to transfer the call. If you're encountering errors when adding message or call forwarding tools, it could be due to incorrect parameters or sequence of operations. Make sure that the message playback is completed before initiating the transfer. If you provide me with the specific Voice API you're using or the error messages you're encountering, I can give you more detailed guidance. If you're unsure about the parameters or the sequence, please ask support for more info on this.
You can continue this conversation by mentioning me in the message.
Got it. Tagging @User for additional help.

im using the Vapi API... im confused
@Vapi im using the Vapi API... im confused
v
@Eddie I apologize for any confusion. To add a specific message before transferring a call using Vapi, you'll need to use the appropriate methods provided by the Vapi API. Typically, this would involve playing a message using text-to-speech or an audio file, and then executing the transfer. Here's a general outline of what the API call might look like: 1. Use the 
speak
method to play your custom message using text-to-speech. 2. After the message has been played, use the 
transfer
method to transfer the call to the desired number. The API call would be structured in a sequence where the 
speak
action is completed before the 
transfer
action is initiated. If you're receiving errors when trying to implement this, it could be due to incorrect API usage or parameter issues. To assist you further, I would need to know the exact error message you're receiving or the code snippet you're using that's causing the issue. If you can provide me with the error details or the part of your code where you're trying to implement the message and transfer, I can give you more specific guidance on how to resolve the issue.

@Vapi Do you have json example?
v
@Eddie Certainly! Below is a JSON example of how you might structure your API call to play a message before transferring the call using Vapi. Please note that this is a generic example and the actual implementation might vary based on the specific methods and parameters required by Vapi.
Copy code
json
{
  "actions": [
    {
      "action": "talk",
      "text": "Please hold while we transfer your call."
    },
    {
      "action": "transfer",
      "destination": "phone_number_to_transfer_to"
    }
  ]
}
In this example: - The first action is 
talk
, which uses text-to-speech to say a message to the caller. - The 
text
field contains the message you want to play before the transfer. - The second action is 
transfer
, which performs the call transfer. - The 
destination
field should be replaced with the actual phone number or SIP address you want to transfer the call to. Make sure to replace 
"phone_number_to_transfer_to"
with the actual number you intend to transfer the call to. Also, ensure that your Vapi API call includes any necessary authentication headers or additional required parameters. If you need to adjust this example to fit the specific requirements of Vapi or if you encounter any issues, please let me know, and I can provide further assistance.

@Vapi im using the "create call" functin with json
v
@Eddie Understood. When using the "create call" function with JSON in Vapi, you would typically set up a sequence of actions that the call should follow. If you want to play a message before transferring the call, you would include a 
talk
action followed by a 
transfer
action in your JSON payload. Here's an example of how you might structure your JSON payload for the "create call" function:
Copy code
json
{
  "to": [{"type": "phone", "number": "destination_phone_number"}],
  "from": {"type": "phone", "number": "your_phone_number"},
  "answer_url": ["https://yourserver.com/answer"]
}
And then, on your server at 
https://yourserver.com/answer
, you would return a JSON response with the actions for the call:
Copy code
json
[
  {
    "action": "talk",
    "text": "Please hold while we transfer your call."
  },
  {
    "action": "transfer",
    "destination": {
      "type": "phone",
      "number": "phone_number_to_transfer_to"
    }
  }
]
In this example: - The 
to
field contains the destination of the outbound call. - The 
from
field contains your phone number or identifier. - The 
answer_url
field points to a URL on your server that will provide the instructions (or NCCO, Nexmo Call Control Object) when the call is answered. When the call is answered, your server should respond with the JSON containing the 
talk
and 
transfer
actions. The 
talk
action will play the message, and the 
transfer
action will transfer the call to the specified number. Please replace 
"destination_phone_number"
, 
"your_phone_number"
, and 
"phone_number_to_transfer_to"
with the actual phone numbers. Also, ensure that the URL provided in 
answer_url
is correctly set up to handle requests and provide the appropriate JSON response. If you need further assistance with the specific JSON structure or if you encounter any issues, please let me know, and I can help you troubleshoot.

@Vapi What if it already has a forwardcall value defined in the json
@Vapi this is when making a call
v
@Eddie If your JSON payload for the "create call" function already includes a 
forwardCall
value, and you want to add a message before the call is forwarded, you would need to modify the JSON response that your 
answer_url
endpoint provides to include a 
talk
action before the 
forwardCall
action. Here's an example of how you might adjust the JSON response provided by your `answer_url`:
Copy code
json
[
  {
    "action": "talk",
    "text": "Please hold while we transfer your call."
  },
  {
    "action": "forwardCall",
    "destination": {
      "type": "phone",
      "number": "phone_number_to_transfer_to"
    }
  }
]
In this adjusted example: - The 
talk
action is added to play a message using text-to-speech before forwarding the call. - The 
forwardCall
action (which might be named differently, such as 
transfer
, depending on your API's specific terminology) is used to forward the call to the specified number. Please ensure that the 
destination
field within the 
forwardCall
action is set to the correct phone number you wish to forward the call to. If the 
forwardCall
action is part of the initial JSON payload for the "create call" function, you would typically not include it there but rather in the JSON response from your 
answer_url
endpoint, as shown above. If you're still having trouble or if the 
forwardCall
action is a requirement within the initial "create call" payload, please provide me with the specific JSON structure you're working with, and I can give you more tailored advice.
@Eddie If you're making a call and want to include a message before the call is forwarded, you'll need to set up your JSON payload to include a sequence of actions. The 
forwardCall
action you mentioned might be specific to your API, but typically, the action to forward a call in many APIs is 
transfer
. Here's an example of how you might structure your JSON payload for the "create call" function to include a message before forwarding:
Copy code
json
{
  "to": [{"type": "phone", "number": "destination_phone_number"}],
  "from": {"type": "phone", "number": "your_phone_number"},
  "ncco": [
    {
      "action": "talk",
      "text": "Please hold while we transfer your call."
    },
    {
      "action": "transfer",
      "destination": {
        "type": "phone",
        "number": "phone_number_to_transfer_to"
      }
    }
  ]
}
In this JSON payload: - The 
to
field specifies the destination of the outbound call. - The 
from
field specifies your phone number or identifier. - The 
ncco
field contains an array of actions to be executed during the call. NCCO stands for Nexmo Call Control Object, which is used by Vonage's Voice API, but the concept is similar in other APIs as well. - The first action is 
talk
, which plays a message to the caller. - The second action is 
transfer
, which forwards the call to the specified number. Please replace 
"destination_phone_number"
, 
"your_phone_number"
, and 
"phone_number_to_transfer_to"
with the actual phone numbers. Also, make sure that the action names (
talk
, 
transfer
) and structure match the requirements of your specific Voice API. If 
forwardCall
is indeed the correct action for your API, replace 
transfer
with 
forwardCall
and adjust the parameters accordingly. If you encounter any issues or need further clarification, please let me know, and I can provide additional assistance.
