AI phone agents that answer, book and route calls around the clock
Answer inbound calls around the clock, qualify leads, resolve routine requests and hand off to staff with warm or direct transfers when a call needs a person.
Reviews conversations across every channel to show where the agent drifted from your brief and where customers hit friction, separating communication issues from business blockers.
Handle callers and message senders in the languages your market needs, with tone, responses and instructions configured around your brand.
Connect Google or Outlook Calendar, Acuity, Clio, Zendesk, Freshdesk and more, and extend the same agent to web chat, SMS, WhatsApp, email and social DMs as an add-on.
Build, test, and deploy production-grade voice AI agents over API
Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
