For ACS direct routing SIP signaling the SBC must be able to negotiate one of four cipher suites: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 or TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256. in context
Azure Communication Services direct routing supports only TLS 1.2 for SBC signaling. in context
