Twilio Programmable Voice React Native SDK: Preflight API now available in GA

We’ve added the Preflight API to the Twilio Programmable Voice React Native SDK, bringing the same pre-call diagnostics available in the native iOS and Android SDKs to React Native apps. Preflight provides a pre-call assessment of network stability, bandwidth, latency, jitter, MOS scores, and packet loss. Use it to surface network warnings, prioritize mobile data, or block calls on unreliable networks, improving connection success and call quality.

Check out the docs for integrating Preflight into your Voice application. We can’t wait to see what you build!
