TLS v1.0 and 1.1 Support Deprecation

As of September 11, 2025, Twilio Voice, Video, and Conversations will no longer support TLS v1.0 and v1.1 for the following endpoint:

sdk.twilio.com (used to host assets and SDK documentation related to Voice, Video, and Conversations)

Any connection attempts made after this date will fail. Due to TLS security vulnerabilities, we will stop offering TLS 1.0 or 1.1 protocols on this date; only the TLS 1.2 protocol will be supported.
