From Draft
"If a response other than a 1xx or a 3xx is received, the UAC SHOULD assume that the UAS does not recognize or support the PING method but the UAC SHOULD accept the response as if it were a 200 OK response."
What UAC should do if it receives 401,405,407,480,482,483,600 response for the PING request ?

There is a draft being discussed on the SIP list right now to implement
a PING method. See http://www.cornfed.com/ping.txt or
http://www.cornfed.com/ping.html for the most recent version. All
comments are welcome since this is a very new draft.
