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

    The 200 Ok can have the port number in m line set to 0 to 
indicate that the media stream is not acceptable.
