No, the periodic ‘liveness’ commands are intended to test that the TCP connection is still alive, and also to compensate for a large number of servers that require these periodic commands in tell them that their client (in this case, the proxy server) is still alive.  However, they were never intended to test for every possible way that a server might be buggy.

If a server does not respond at all to an incoming “OPTIONS” command (and the RTSP TCP connection is still alive), then the server is badly broken.  You need to repair (or replace) your server.

(If the server just ‘dies’ - taking down the RTSP TCP connection with it - then, of course, we will detect and handle this.  This is the normal way in which a server will fail to handle an “OPTIONS” command.)
