Give your AI agent a phone number for iMessage and FaceTime
Send from a phone number into real blue-bubble threads, with automatic fallback to SMS or RCS when a recipient is off iMessage.
Give your agent a voice and a face so users can talk things through or show the agent what they need help with.
Track delivery and read status per message, with webhook-ready events so your systems know what happened.
Attach PDFs, menus, decks, links, voice notes and contact cards inside the same native conversation.
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.
