Call recording

Voximplant allows users to record an audio or video call.

To start a call record, use the call.record() method in your scenario. The record is saved in your Voximplant cloud or in your custom S3-compatible storage.

If you need to record video as well as audio, set the video parameter of the call.record() method to true.

Refer to the code example below to understand how it works:

Optionally, you can use the Recorder module to record a call. However, the Recorder module supports only audio recording.

You can pass one or several parameters to the call.record() method or to the Recorder module in order to customize your records.

Here are the most common parameters to customize:

  • expire: specifies how long to store the record in the cloud. Can be set to 3 or 6 months, 1, 2, or 3 years

  • contentDispositionFilename: specifies the record filename in the cloud

  • hd_audio: if true, the record is 192kbps/48KHz. The default value is 32kbps/8KHz

  • lossless: if true, saves the record in the flac format

  • stereo: specifies whether the record is stereo or mono

You can find the complete recorder parameters here.
