200 OK in calling state for INVITE client transaction

    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

Hi Sudhir,



ACK must contain the same To- tag as
recevied in 200 OK for invite, because to-tag is used to identify dialog
for which this ACK is received.
