Real phone call

Have your agent call an actual phone

Enter a phone number in international format. Callora dials it from a US number and your configured agent talks live via GPT-realtime.

How it works
  1. We save your agent config server-side
  2. Twilio dials your phone from a real US number
  3. When you answer, Twilio streams audio to a WebSocket bridge
  4. Bridge forwards audio (g711 μ-law) to OpenAI Realtime
  5. Agent talks. Transcript + analysis saved to your history.
