Although ACK is not a part of INVITE transaction, but I think it must have same dialog-id as INVITE transaction. So To-Tag, From-Tag & Call-ID MUST be same as 200OK/180Ringing to INVITE.
Thanks, Dinesh -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of sudhir kumar Sent: Friday, December 21, 2007 9:57 AM To: sip-implementors@lists.cs.columbia.edu Subject: [Sip-implementors] 200 OK in calling state for INVITE clienttransaction Hi All, when an INVITE client transaction is in the Calling state, on receipt of Success (200 OK) response. As per RFC 17.1.1.2(Figure 5: INVITE client transaction), the 2xx response MUST cause the client transaction to enter the "Terminated" state. But, I'm not sure what would be To_Tag in generating ACK for that 200 OK. Any response is highly appericated. Thanks, Sudhir Get the freedom to save as many mails as you wish.
