Voice API

Start, answer, and control calls over HTTPS.

Your backend places the call, receives the inbound webhook, and decides what happens while the line is up.

    Outbound from your backend

    Ask Coocall to dial an E.164 number when a job, a lead, or a schedule says it is time.

    Inbound to a webhook

    When someone calls your number, we request your answer URL and follow the instructions you return.

    Transfer and hang up

    Move a live call to another party, or end it, without waiting for the caller to drop.

  • 04

    Media for your speech pipeline

    Stream call audio to the speech stack you already run, and send audio back onto the call.

  • 05

    Keypad input

    Collect DTMF when a flow needs a menu choice or a code that should stay out of a transcript.
