[SIPForum-discussion] SIP RSeq number in fork case

[Steven Wu]

Hi,
 
In RFC3262 it said that RSeq must increase 1 for the same request.
But in the fork case, UAC maybe receive more than one 183/180 responses for different UAS and maybe with same RSeq.
So, How the UAC handle for the 1xx response with same RSeq number value come from different UAS?
Just skip it or reply PRACK for it?
 
Best regards,
Steven Wu
