Set your credentials once:
AUTH_ID is your Vobiz Auth ID (MA_…), AUTH_TOKEN is your Auth Token. In the Vobiz SDK, api_key is the Auth ID, and every account-scoped method takes that auth_id explicitly.Answer a call with XML (TTS + menu)
The XML builder maps verb-for-verb:VoiceResponse() → ResponseElement(), and Gather keeps its name. On the builder, response.gather(...) → resp.add_gather(...), nested .say() → .add_speak(), and str(response) → resp.to_string(). Twilio’s input/timeout become Vobiz’s input_type/execution_timeout; num_digits carries over unchanged.
Serve the answer URL (Flask / FastAPI / Express)
When Vobiz rings your number it fetches youranswer_url over HTTP - return the VobizXML from any web framework, exactly as your Twilio voice URL returned TwiML. Just build the response with vobizxml instead of VoiceResponse, and send it as application/xml.
