Upcoming changes to parameters passed to <Play> files during <Gather>

On 1 July 2021 Twilio will stop sending HTTP request parameters to <Play> files contained with a <Gather> using speech recognition.

For some call flows using <Gather> with speech recognition Twilio has been passing HTTP parameters when fetching <Play> files. This behavior was not deliberate and can cause issues with pre-signed URLs. An upcoming release will change this behavior and Twilio will no longer pass these parameters.

If your application has been designed in a manner that the HTTP parameters passed in the request to <Play> files is driving your application logic, you will need to update your code by 1 July 2021.
