> 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.
