Frequently Asked Questions
How natural do the AI voices sound on live phone calls?
We use ElevenLabs and Deepgram ultra-realistic neural voice models with sub-800ms latency. Callers typically cannot distinguish the agent from a human representative, as it responds fluidly to interruptions and natural conversation pauses.
Can the AI voice agent check real-time availability and book appointments?
Yes! The bot integrates directly with Google Calendar, Cal.com, or Calendly via API tools to look up available slots, confirm attendee details, schedule bookings, and send instant SMS/WhatsApp confirmation links.
What happens if a customer has a complex query or wants to speak to a human?
We configure intelligent fallback logic: the voice agent can perform a warm live call transfer to a designated human team member's phone number or log an escalation ticket directly into your CRM.
Which telephony providers are supported?
We configure official Twilio SIP trunks, Vonage, or Telnyx, enabling local phone numbers across 100+ countries with inbound receiving and compliant outbound automated calling.
