Summary
-------

If srtp_create fails, session we create for temp will either not be created or else will be dealloced within srtp_create. At present, when we then run ast_srtp_destroy, attempting to dealloc this can cause Asterisk to crash. This patch addresses that by setting the session pointer to NULL so ast_srtp_destroy doesn't attempt to dealloc it.

As one might expect, this patch doesn't resolve the reporter's problems with actually setting up an srtp enabled SIP call, but it does fix a crash which shouldn't be happening.


This addresses bug ASTERISK-20499.

Testing
-------

The reporter has tested the patch and confirmed that it eliminates the crash.


Thanks,

jrose
