             Summary: SRTP authentication failure after hold/unhold
                 Key: ASTERISK-29128
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29128
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_srtp
    Affects Versions: 16.13.0
            Reporter: lvl
         Attachments: filtered.log

As simple as the title indicates. Put an SRTP call on hold, unhold it, and Asterisk starts logging "SRTP unprotect failed on SSRC 1509410849 because of authentication failure" afterwards. No more audio is transmitted.

Traced the problem to commit https://github.com/asterisk/asterisk/commit/c00b032bbfc14f40537989477229f189a1b529d7 (ASTERISK-28903), without it everything works fine.

Asterisk 16.13, libsrtp 1.5.4.
