Subject: Persistent Twilio "Press any key" prompt on outbound calls in Brazil, despite correct Vapi settings Hello Vapi community, I'm facing a persistent issue with all outbound calls made through my Vapi agent and I'm hoping someone here might have a solution. The Problem: Before my agent can speak its first message, an English voice prompt plays asking the user to "press any key to connect". The agent only starts speaking after the key is pressed. My goal is for the agent to speak immediately after the call is answered, without this prompt. Context: I am using a Twilio phone number that I purchased and then connected to my Vapi account. My operations and the numbers I am calling are all located in Brazil. Troubleshooting Steps I've Already Taken: I've spent a lot of time trying to solve this and have confirmed the following: Vapi Agent Config: My agent is correctly configured with "First Message Mode" set to "The assistant speaks first". Vapi Voicemail Detection: I've set the "Voicemail Detection Provider" to "Vapi (recommended)", but the prompt still plays. Direct API Call: I tried making a direct API call via Postman to force the connection using the Twilio parameter "AnswerOnBridge": "true". However, the Vapi API returned a 400 Bad Request error with the message: ["property provider should not exist", "property twilioParams should not exist"]. This shows I cannot override this behavior via the API. Twilio Account: I have checked my Twilio account and confirmed there are no "TwiML Bins" or "TwiML Apps" configured that could be causing this prompt. My Question: Has anyone, especially other users in Brazil or outside the US, encountered this specific issue? Is there a known workaround or a specific account setting (either in Vapi or on the Twilio side) that I need to change to disable this pre-call screening prompt? Any help would be greatly appreciated! Thank you.
