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
