OM...
As you know per RFC 3261 OPTIONS is meant
-implementors] Determinine if a SIP device is alive.

Will having a few less headers really have much affect in CPU time?
Since it is a SIP message, UAS will have to do all the things necessary
to process any SIP request.
Another point, although a 200 OK response makes sense

Andy, my take - it really depends on what you mean by 'active'. For example,
the device could be active but due to some error, may not be functioning as
a SIP entity any more (maybe the SIP stack crashed into an invalid state ;-)
but the device is alive at the IP and phy level)

a PING method. See http://www.cornfed.com/ping.txtor
