It means that the ACK is different transaction. For a 6361 implementation, this means that
the branch ID should be different from the branch ID that was used for the INVITE transaction,

Subject: [Sip] CSEQ Number in ACK to 2xx Response for INVITE???

Hello all,

In section 13.2.2.4 2xx Responses,it is mentioned that while generating an ACK for a 2xx response should have same CSeq number as in INVITE but the method as ACK.

But is mentioned in Definition section that ACK for a 2xx response to an INVITE request is a separate transaction.Does it mean that CSEQ number to be incremented?
