When do you download my file when using Voice API?


Question

When are the NCCO and audio file for a stream downloaded?

Applies To

  • Voice API
  • Call Recordings

Answer

When using the Voice API, Vonage will download the file when it is required.

NCCO

The Nexmo Call Control Object (NCCO) is downloaded when a call is answered. For an outbound call, this will be when the first recipient answers. For an inbound call, Vonage will answer the call and then download the NCCO.

Stream Audio File

The audio file for a stream action is downloaded when it is needed. This means that the MP3 or WAV file will be downloaded when the Voice API reaches the stream action. If you have actions before your stream, these will be processed before the file is downloaded.
