FAQ
Which platform is better: Vapi AI or Retell AI?
Both deliver sub-second latency and realistic voices. Vapi offers deep custom workflow control, while Retell excels at out-of-the-box reliability. I will recommend the best fit based on your phone system and CRM stack.
Can the AI voice bot book appointments in real time?
Yes. Using webhook actions, the voice agent checks your live availability on Google Calendar or Calendly during the phone call and reserves the slot instantly.
Do I need my own Twilio and AI platform accounts?
Yes. You will need your own accounts (Twilio for the phone number, plus Vapi/Retell and OpenAI API keys) so you keep full ownership and direct billing for call minutes. I will guide you through connecting them.
Can the voice caller transfer calls to a human agent?
Yes. If a caller asks for a live representative or reaches an emergency condition, the agent can immediately forward the call to any human phone number.
