Anyone knows how to do call transfer to a number in the last version of Vapi? it used to work but know when it triggers the call transfer the assistant hangs up. I tried to call from another phone number and tried different destination numbers. Is the only way now workflows? I used this config in API create request: "tools": [ { "type": "transferCall", "destinations": [ { "type": "number", "number": "+3**3", "message": "Transfering...." } ] } ], "function": { "name": "transferCall", ...... I see on dashboard that redirect number is not beign filled
