> Asterisk uses OpenSSL als crypto library. Currently for DTLS, the first version (based on TLS 1.1) is used -- always. DTLS 1.0 is used even if the installed OpenSSL supports newer DTLS versions. For example since OpenSSL 1.0.2 -- included in Ubuntu 16.04 LTS -- DTLS 1.2 is supported.
> DTLS 1.2 is used by Mozilla Firefox for WebRTC ([DTLS-SRTP|https://tools.ietf.org/html/rfc5764] via [SIP-over-Secure-WebSockets|https://tools.ietf.org/html/rfc7118]). Furthermore, DTLS 1.2 is required for AEAD-based cipher-suites like {{TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256}} and/or {{TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256}}.
