Recordings

Recordings are generated when you use the <Record> verb. Those recordings are hosted with Restcomm for you to retrieve. The Recordings list resource represents the set of an account’s recordings.

Recording Resource URI

/2012-04-24/Accounts/{AccountSid}/Recordings/{RecordingSid}

To download the audio file just append .wav after the RecordingSid.

The URLs that contain the actual audio recordings are accessible by everyone without the need to authenticate with Restcomm. This is per design to allow for your apps to easily access the recordings without revealing your credentials. The same is NOT true for the resource to retrieve the list of recordings so unauthenticated users cannot access the RecordingSid and hence not able to download the actual recording.

Although Recording Sids in Recording URLs are essentially long random strings that are very difficult to guess, you still need to make sure that they don’t fall in the wrong hands

Get List of Recordings

Here’s how you can list your recordings:

curl -X GET https://mycompany.restcomm.com/restcomm/2012-04-24/Accounts/ACCOUNT_SID/Recordings.json \

const request = require('request');

<Sid> holds the file name of the recorded message. The recording Sid.wav is available in the file system only.

If you want to return the recording url you will need to parse the <Uri>/2012-04-24/Accounts/ACae6e420f425248d6a26948c17a9e2acf/Recordings/REb4c03af76cdc4a27aad0d9d759e119bc</Uri> response from Restcomm and add the extension .wav

The <Uri> holds the http URI that can be used for playback or to download the recorded message. Here is how to access the file using http https://$DOMAIN/restcomm/recordings/REb4c03af76cdc4a27aad0d9d759e119bc.wav`

Sorting Information

HTTP GET. You can use the SortBy GET query parameter to determine which attribute you want to sort by and in which direction; direction can either be 'asc' for ascending and 'desc' for descending sort ordering. Here’s the overall format: SortBy=<sorting attribute>:<direction>. If no direction parameter is provided, then the listing of recordings is sorted by the attribute in ascending order. Below you can find the possible attributes you can sort by:

SortBy Attributes

Parameter	Description
DateCreated	Sort by date at which the recording was created
Duration	Sort by the duration of the recording
CallSid	Sort by the CallSid of the recording, which points to the call to which the recording is related to

Parameter

Description

DateCreated

Sort by date at which the recording was created

Duration

Sort by the duration of the recording

CallSid

Sort by the CallSid of the recording, which points to the call to which the recording is related to

Example

The command below will return recordings sorted by the creation date in ascending order using SortBy parameter:

curl -X GET https://mycompany.restcomm.com/restcomm/2012-04-24/"Accounts/ACCOUNT_SID/Recordings.xml?SortBy=DateCreated:asc' \
