 To define that an XForm should be converted to an SMS, add the field `xml2sms` to the form's CouchDB doc and assign it a truthy value (either a boolean or a string).  
 When submitting such a form, along with creating the report document, the app will try to compact the report's content into an SMS that would be sent to the configured Gateway phone number.

 There are many supported formats for video, audio, and images. We recommend using h.264(mpeg) for video, jpeg for images, and mp3 for audio. When creating videos or images keep in mind the dimensions and storage capabilities on phones that may be used. Lower end phones have smaller storage and screen sizes. When rendering images, video, and audio the CHT uses the browser's built in rendering tools. This means you can render any media format that is supported by the [minimum version of Chrome]({{< ref "core/overview/supported-software#dependencies" >}}).

The translation uses a summary of the report as the evaluation context so you can include report fields in your value, for example: `Case registration {{case_id}}`. Useful properties available in the summary include: `from` (the phone number of the sender), `phone` (the phone number of the report contact), `form` (the form code), `subject.name` (the name of the subject), and `case_id` (the generated case id).
