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.

[Sip] 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_______________________________________________
