> When calling in this situation 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 completes successfully.
