<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Removal of the call to SSL_get_peer_certificate from here is incorrect. SSL_get_verify_result will return X509_V_OK if no peer certificate was presented, so you need to use both to confirm verification actually occurred.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">When calling using TCP/TLS with an invalid CA certificate for the key in use and tlsdontverifyserver is set to no, Asterisk produces the error message:
ERROR[16872]: tcptls.c:199 handle_tcptls_connection: Certificate did not verify: certificate signature failure
This should cause the call to fail, but it does not. The call instead completes successfully. This patch corrects that behavior as well as avoids a segfault if the remote end does not provide a certificate at all.
