Phew...
1/ The interval between two successive "OPTIONS" commands will almost never 
exceed the "timeout=" parameter that the server reported.  (A future release of 
the software will ensure that it *never* exceeds this - because the interval 
will be randomly chosen from "[delayMax/2,delayMax-1)" instead of the current 
"[delayMax/2,delayMax)".)
2/ In any case, this shouldn't matter, because - as I've said AD NAUSEAM - the 
proxy server will send RTCP "RR" packets far more frequently than this, and 
standards-compliant (i.e., correctly implemented) server will use these as an 
indication that the proxy server is still alive.
3/ Should the camera "time out the shutdown the session" - for any reason - 
then the subsequent "OPTIONS" command from the proxy server will fail, and the 
proxy server will then reopen the connection.  That's the PRIMARY PURPOSE of 
the periodic "OPTIONS" commands: To check whether the server still thinks that 
the session is alive.
