The Record element

You can use the Record element to record a call and return the URL of the recording file. Attributes

action `string` Callback-retry configurable	Submit the result of the record to this URL. See the table “Parameters sent to the action URL” below for more information. Allowed values: a fully qualified URL
method `string`	Method used to send HTTP request to the `action` URL. Allowed values: GET, POST Defaults to POST.
fileFormat `string`	The format of the recording. Allowed values: `mp3`, `wav` Defaults to `mp3`.
redirect `boolean`	If `false`, don’t redirect to the `action` URL, only request the URL and continue to the next element. Allowed values: `true`, `false` Defaults to `true`.
timeout `integer`	Seconds of silence before considering the recording complete. Only used when `recordSession` and `startOnDialAnswer` are `false`. Allowed values: positive integer Defaults to 15.
maxLength `integer`	Maximum number of seconds to record. Allowed values: integer greater than 1 Defaults to 60.
playBeep `boolean`	Plays a beep before recording. Only used when `recordSession` and `startOnDialAnswer` are `false`. Allowed values: `true`, `false` Defaults to `true`.
finishOnKey `string`	Stop recording when this key is pressed. Only used when `recordSession` and `startOnDialAnswer` are `false`. Allowed values: any digit, `#`, `*` Defaults to `#`
recordSession `boolean`	Record current call session in background. No beep will be played. Allowed values: `true`, `false` Defaults to `false`.
startOnDialAnswer `boolean`	Record call when called party answers in a Dial. No beep will be played. Allowed values: `true`, `false` Defaults to `false`.
transcriptionType `string`	`auto`: Transcription is automated; the turnaround time is under 5 minutes which linearly increases with call duration. Transcriptions charge details are available on our pricing page.
Note: The transcription service is available only in English, and limited to calls with a duration greater than 500 milliseconds and less than four hours with a recording file size smaller than 2GB.
transcriptionUrl `string` Callback-retry configurable	The URL where the transcription is to be sent from Plivo. See the table “Parameters sent to the transcription URL” below for more information. Allowed values: a fully qualified URL No default value.
Note: The transcription information will be sent to this URL via an HTTP POST callback.
callbackUrl `string` Callback-retry configurable	If set, this URL is fired in the background when the recorded file is ready to be used. See the table “Parameters sent to the callback URL” below for more information. Allowed values: a fully qualified URL
callbackMethod `string`	The HTTP method used to notify the `callbackUrl`. Allowed values: GET, POST Defaults to POST.
recordChannelType `string`	Specifies the recording channel type. Allowed values: `mono, stereo` Defaults to `stereo`.

Notes:

If recordSession is set to true, recording will start in the background and will continue until the call is hung up or maxLength is reached.
If startOnDialAnswer is set to true, Plivo will record the complete conversation between both parties during the next Dial and will end when the Dial is done or maxLength is reached. This may not be legal in some countries.
timeout, finishOnKey, and playBeep attributes have no effect when recordSession or startOnDialAnswer is set to true.
The default recording time is 60 seconds if maxLength is not set.
If recordChannelType is set to mono, the recording will have a single audio channel combining all participants in the call.

Parameters sent to the action URL

RecordUrl	Complete path to the recorded file URL.
Digits	If set, the digits pressed to stop the recording.
RecordingDuration	Duration of recording in seconds.
RecordingDurationMs	Duration of recording in milliseconds.
RecordingStartMs	When the recording started (epoch time UTC) in milliseconds.
RecordingEndMs	When the recording ended (epoch time UTC) in milliseconds.
RecordingID	Recording ID of the file.

Notes:

If startOnDialAnswer or recordSession is set to true, an initial request is made to the action URL as soon as the recording has started. Because of this, RecordingDuration, RecordingDurationMs, RecordingStartMs, and RecordingEndMs will all be -1. No other request will be made to the action URL once the recording is completed.
If startOnDialAnswer and recordSession are set to false, a request is made to the action URL only when the recording is completed. This request will contain the actual values of the recording.

Parameters sent to the callback URL

RecordUrl	Complete path to the recorded file URL.
RecordingDuration	Duration of recording in seconds.
RecordingDurationMs	Duration of recording in milliseconds.
RecordingStartMs	When the recording started (epoch time UTC) in milliseconds.
RecordingEndMs	When the recording ended (epoch time UTC) in milliseconds.
RecordingID	Recording ID of the file.

Parameters sent to the transcription URL

transcription_charge	The credit deducted for the transcription.
transcription	Transcribed text of the recording.
duration	Duration in seconds of the recording.
call_uuid	Call UUID of the call that was transcribed.
transcription_rate	Rate of the transcription per minute.
recording_id	Recording ID of the recording that was transcribed.
error	Can be `Recording duration too long for transcription` or `Recording file size too large for transcription`. Empty if transcription is successful.
Note: .mp3 files are smaller in size than .wav files. Consider changing the recording file format to `mp3` if you see this error.
