can anyone help me - trying to setup inbound transient with the exact data from the documentation and it keeps going to the fallback number What I am sending (as in documentation) { "assistant": { "firstMessage": "Hey Ryan, how are you?", "model": { "provider": "openai", "model": "gpt-3.5-turbo", "messages": [ { "role": "system", "content": "You're Ryan's assistant..." } ] } } }
