Twilio Changelog

Additions and changes to the Twilio platform

As previously communicated, Twilio is adding functionality to the Programmable Voice <Dial> verb. Although the new features are specific to SIP Connectivity via <Dial><Sip>, the new functionality may affect your existing applications using <Dial>, <Dial><Client>, and <Dial><Number>. <Dial><Conference> and <Dial><Queue> are not impacted.The deadline to account for these changes in your application code is 16 November 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 16 November 2021 to identify any potential impacts.

The new features can be enabled on the Programmable Voice Settings page by clicking the Enable Advanced Programmable SIP Features setting. This will activate the new features on an account-wide level.

Twilio initially communicated that these features will be applied to all accounts after 31 July 2021, but following customer feedback we extended the testing period to 16 November 2021.
