FAQ
What accounts do I need to get started?
You will need active accounts on Vapi or Retell AI, Twilio, and your CRM (e.g., GoHighLevel). I can assist you during setup if needed.
How does Twilio number rotation prevent spam flagging?
By cycling through a designated pool of Twilio numbers and managing call pacing, your phone numbers avoid getting flagged as "Spam Likely," significantly improving answer rates.
Can the AI agent book appointments directly on my calendar?
Yes. The agent checks real-time availability and schedules appointments directly into Google Calendar, Outlook, or GoHighLevel Calendars during the call.
