Additions and changes to the Twilio platform
Twilio is adding functionality to the Programmable Voice <Dial> verb specific to SIP Connectivity. The new functionality may affect your existing applications. The deadline to account for these changes in your application code is 31 July 2021.
In most cases, your existing code will continue to function; however, there are some functional improvements and behavioral changes which could possibly impact your application. We recommend testing your existing application code in dev or staging environments before 31 July 2021 to identify any potential impacts..
The new features can be enabled on the Programmable Voice Settings page. This will activate the new features on an account-wide level. These features will be applied to all accounts after 31 July 2021.
We are planning to enable this new feature set across all Twilio accounts on 31 July 2021, and will allow you enough time to adjust your applications to use this new functionality, and fully test these changes. As always, Twilio will always be there to help you through this process, if you need assistance, or run into problems.
