[SIPForum-discussion] SIP RSeq number in fork case

[Wayne.Davies]

There should be no conflict / issue because in forking scenario the
different 18x requiring 100rel are specific to their own early dialog,
so UAC should send PRACK with relevant RSeq per early dialog requiring
it.

Subject: [SIPForum-discussion] SIP RSeq number in fork case

 

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
