is there a way to start a call transfer while the agent is still talking?

@YinYang Yes, absolutely! The transferCall function can be initiated even while the agent is still on the line. Would you like to proceed with transferring the call right now? If so, please provide the forwardingPhoneNumber or confirm if I should use the one already on file.

@Shubham Bajaj i need help setting this up

@YinYang Could you please clarify your question about "starting a call transfer while the agent is still talking"? For example, are you looking to initiate a transfer when the Assistant says something specific (let's call it message X), wait for that message to be fully voiced, and then complete the transfer? Please provide more details about your use case.

yes. Wondering if it is possible for the agent to make the call to the live transfer agent while the ai agent is "warming" up the prospect becasue I find alot of customers hang up whenever they get transfered after 2-3 seconds

You can either use a prompting technique that first generates content and then performs tool calling or live call control. Here are two approaches: [1] Say your content and trigger transferCall at the same time. [2] Use ClientInboundMessageTransfer to externally trigger the transfer call and pass the content to be spoken. Just replace the call ID and other information with your own values.

example

curl --location 'https://aws-us-west-2-production1-phone-call-websocket.vapi.ai/<your-call-id>/control' \
--header 'content-type: application/json' \
--data '{
  "type": "transfer",
  "destination": {
    "type": "number",
    "message": "insert-say-message-here",
    "number": "insert-destination-number-here",
    "numberE164CheckEnabled": false
  }
}'
