Using the Record API
The Record API can record live calls at any time during the call. The API will return a URL with a file containing the audio recording. For more details, please read this guide: https://www.plivo.com/docs/api/call/record/#record-a-call
To get the call_UUID of an ongoing conference call, use this API: https://www.plivo.com/docs/api/conference/#details-of-a-conference
Using record attribute in conference XML
You can use the ‘record’ attribute by setting it to ‘true’ in the conference XML to record a conference call. For example:
<Response>
<Conference record="true">My Room</Conference>
</Response>
You can also set up the recordFileFormat as either .mp3 or .wav. Click here for more details: https://www.plivo.com/docs/xml/conference/#attributes
