So I mean if you make create call and start your VAPI Workflow or Assistant from a Twilio Serverless Function. 😄 Hope that makes sense
For me I couldnt directly transfer, so I started in Twilio so Twilio has the "rulership" over my call and just call VAPI like any other webhook.
I used the VAPI Docs "Call handling with VAPI and Twilio", there is a step by step with code and what is happening.
