The basic defintion says why it is considered that way. Specifically, a SIP transaction consists of a single request and any responses to that request, which include zero or more provisional responses and one or more final responses. Transaction is complete with atleast one final responses. For a non-200OK, there has been no final response yet so it is considered the same transaction. The moment the final response comes back ( 200OK), the transaction is complete...for INVITE, the 200OK compeles the transaction. M

If the request is INVITE and the final response is a non-2xx, the transaction also includes an ACK to the response. The ACK for a 2xx response to an INVITE request is a separate transaction. My query is why ACK is considered as a part of same transaction when in case of non-2xx response.? regards VIkram _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
