------------------------------------------

             Summary: [patch] libsrtp-2.1.x support
                 Key: ASTERISK-27253
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27253
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Resources/res_srtp
    Affects Versions: 13.15.1
            Reporter: Alexander Traud
            Severity: Minor


Since ASTERISK-26976, libSRTP 2.0.x can be linked. However since libSRTP 2.1.x, the macro {{SRTP_AES_ICM}} got renamed to {{SRTP_AES_ICM_128}} (see commit [2a481bb|http://github.com/cisco/libsrtp/commit/2a481bb1434e4bbb2ce6c95ce1ec227e6e344259] and [d335bd8|http://github.com/cisco/libsrtp/commit/d335bd88b147cf0fdf956bd21a55d3c7c9d974d7]). Because of that, Asterisk 13 does not compile when libSRTP 2.1.x is present:
