I'm trying to get how the call forwarding works in Vapi, and I want to make sure I'm getting it well. The steps I should follow if I want that my assistant forward a call are: * Use the transferCall tool and add the instructions in the assistant's prompt to forward the call. * Set up the Server URL and activate the transfer-destination-request events. * In my server, when I receive a message from the transfer-destination-request webhook, create my logic and return a response to that webhook with the number to forward. Is this process correct? Also, is it possible to have a different Server URL only for these events?

@Vapi Just to be clear, does the transferCall tool initiate the call transfer automatically? or does it set up the option to forward the call to a different phone number based on the conversation with the customer and the instructions in the call prompt? Because I need the option number 2

@Juan The

transferCall

tool sets up the option to forward the call to a different phone number based on the conversation with the customer and the instructions in the call prompt. It does not initiate the call transfer automatically; instead, it allows you to define conditions under which the call should be transferred. For example, you can program your assistant to use the

transferCall

function when certain criteria are met during the interaction with the customer, such as when a specific request is made or a particular issue is identified that requires escalation to a human operator.

@Juan Yes the process you have mentioned you is correct and you can use different server urls for assistants. FYI: for transfer call it it not mandatory to use

transfer-destination-request

unless you want to set dynamic destinations for the call transfers.

Did you get this working for dynamic transfers @Juan ? I have the bare bones working but am unsure what the correct structure to return for the transfer and initial the call, i thought it was @Shubham Bajaj

@~Stu~ CoreAspect.Agency Sorry for the late response. Are you still experiencing this problem? If so, could you share the following info in a new #1211483291191083018 ticket: - The recent call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help me figure out what went wrong!
