How to Compile and Install Coturn 4.6.2 with TLS 1.3 Support on Debian 12 (Bookworm)

Coturn is the standard open-source STUN/TURN server enabling WebRTC audio/video connections across symmetric NATs and firewalls. Full support for modern TLS 1.3 encrypted TURN connections (TURNS) was added in Coturn 4.6.2. Because Debian 12 (Bookworm) originally packaged Coturn 4.6.1, compiling version 4.6.2 from source with OpenSSL 3.x is necessary for enterprise TLS 1.3 compliance.

Features: TURNS over TLS 1.3 • WebRTC relay performance • Debian 12 Bookworm
