# More Recording Options for TeXML

### 23, Feb 2021

We're adding more flexibility when recording calls using TeXML, allowing you to choose between single- or dual-channel call recording more easily.

### How to specify Single-Channel Recording via TeXML

Recording calls using the TeXML 

[<Record>](https://developers.telnyx.com/docs/voice/programmable-voice/texml-translator#record "Call Control API Reference | Telnyx Developer Center")

 verb produces a dual-channel recording by default.

Now, users can specify an additional 

channels

 attribute with the 

<Record>

 verb to produce a single-channel recording:

<Response> <Record **channels="single"** action="/test/callback/on-record" method="POST" recordingStatusCallback="/test/callback/recording" /> </Response>

The channels attribute can have a value of 

"single"

 or 

"dual"

. The default value is 

"dual"

, so if you're already using TeXML to record dual-channel calls, your integration won't be affected.

### How this change affects webhook information passed by Telnyx

Telnyx passes information about recordings in the form of a webhook sent to the 

recordingStatusCallback

 and 

action

 URLs specified in the 

<Record>

 verb. With this change, the information in the webhooks will include a new 

"RecordingChannels"

 field. The 

"RecordingChannels"

 field can have a value of 

"1"

 for single-channel recordings or 

"2"

 for dual-channel recordings.

The webhook example shown below describes a single-channel call recording:

{ "AccountSid": "9fd26e62-XXXX-XXXX-XXXX-XXXXXXXXXXXX", "CallSid": "v2:Yl-sKJ4znm3N7v9-nstE9oJNH48s4PfWVJ1UB5nsJMKHS9RqQ6gNdg", "CallSidLegacy": "v2:Yl-sKJ4znm3N7v9-nstE9oJNH48s4PfWVJ1UB5nsJMKHS9RqQ6gNdg", "From": "+1555XXXXXXX", **"RecordingChannels": "1",**"RecordingDuration": "4", "RecordingSid": "f1099038-XXXX-XXXX-XXXX-XXXXXXXXXXXX", "RecordingStatus": "completed", "RecordingUrl": "S3 URL", "To": "+1555XXXXXXX" }

This change will be in effect from **Monday, March 1, 2021**. Want to learn more about recording calls with TeXML? Visit our [API reference](https://developers.telnyx.com/docs/voice/programmable-voice/texml-translator#record "Call Control API Reference | Telnyx Developers") to explore the docs!
