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
