FAQ

AI voice calling, answered

What is AI voice calling?

AI voice calling is software that places real outbound phone calls using a natural, human-like AI voice agent that speaks and listens in real time, qualifies intent and books meetings, then logs the outcome. DueDoor runs the whole loop on-device and dials from your own SIM for a local number.

How is DueDoor different from a cloud dialer?

Cloud dialers call from foreign or virtual numbers people ignore and bill per minute per seat. DueDoor dials from your own SIM for a local number and your own minutes, runs full-duplex conversational AI with barge-in, and scales as one device.

Can the AI voice agent call from my own number?

Yes. Insert your nano-SIM into the DueDoor calling device and the AI voice agent dials from that local number, using your own minutes, so answer rates stay high.

What languages and voices does it support?

80+ natural voices across many languages and accents, including Hinglish and regional Indian languages, with real-time full-duplex speech and barge-in.

Does every AI call get logged to my CRM?

Yes. Every call is transcribed with an intent score and outcome and written straight into your DueDoor pipeline.
