If no "subscribe_context" is specified, then the "context" setting is used. +res_rtp_asterisk +------------------ + * The DTLS part in Asterisk now supports Perfect Forward Secrecy (PFS). + Enabling PFS is attempted by default, and is dependent on the configuration + of the module using TLS. + - Ephemeral ECDH (ECDHE) is enabled by default. To disable it, do not + specify a ECDHE cipher suite in sip.conf, for example: + dtlscipher=AES128-SHA + - Ephemeral DH (DHE) is disabled by default. To enable it, add DH parameters + into the private key file, e.g., sip.conf dtlsprivatekey. For example: + openssl dhparam -out ./dh.pem 2048 + - Because clients expect the server to prefer PFS, and because OpenSSL sorts + its cipher suites by bit strength, see "openssl ciphers -v DEFAULT". + Consider re-ordering your cipher suites in the respective configuration + file. For example: + dtlscipher=ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256 + which forces PFS and requires at least DTLS 1.2. + ------------------------------------------------------------------------------ --- Functionality changes from Asterisk 13.9.0 to Asterisk 13.10.0 ----------- ------------------------------------------------------------------------------ |
