Twilio Elastic SIP Trunks do support call recording. When recording is enabled, all calls are recorded (both origination and termination traffic), in a pay-as-you-go consumption model. 

Elastic SIP Trunking Call Recording Options

There are three different recording settings to select from:

• Do Not Record (Default option): Recording is disabled on this trunk.
• Record from Answer: Recording will begin when a call is answered.
• Record from Ringing: Recording will begin when the ringing starts.

Enable Call Recording for an Elastic SIP Trunk

1. Login to your project at www.twilio.com/console.
2. Select Elastic SIP Trunking > Trunks, or click here.
3. Click the desired SIP Trunk to modify.
4. Click the Recording Setting drop-down menu, and then select the desired recording option.
5. Click Save.

Access Call Recordings in Console

Single call recordings can be viewed and manually deleted one at a time from the Recordings log in Console:

1. Login to your project at www.twilio.com/console.
2. Select Elastic SIP Trunking > Logs, or click here.
3. Navigate to and select the desired recordings -
• From Calls logs: select the desired call, and then click on the Recording SID.
• From Recordings logs: click the desired recording.
4. From here, you can play or delete a recording.

Access Call Recordings Programmatically via the REST API

Call recordings can be be accessed via calls to the Recordings API resource.

• HTTP DELETE requests are used to delete call recordings.
• HTTP GET requests are used to download call recordings.

To download or delete multiple recordings using the API, a script would be required that iterates over the list of recordings, making a separate API request for each action.
