OK. But what should be the body of the 200 OK PRACK (Pattern 5)  before sending 
488 to INVITE for termination of the dialog.

        Hi,
         
        I have a call scenario, where UAC had sent an offer (not initial) in 
PRACK and the UAS needs to refuse the offer. Can the UAS refuse the offer using 
a 4xx response (e.g. 488) ? I don't find any specific example in the currently 
available RFCs and/or drafts.
         
        Cheers,
        Subhodeep
