Re: [OpenSER-Users] No answers whatssoever??

Hi Taisto, As mentioned in a previous email, the RFC3261 says that the 200OK ACK forms a separate transaction: 17 Transactions (page 122) .... The reason for this separation is rooted in the importance of delivering all 200 (OK) responses to an INVITE to the UAC. To deliver them all to the UAC, the UAS alone takes responsibility for retransmitting them (see Section 13.3.1.4), and the UAC alone takes responsibility for acknowledging them with ACK (see Section 13.2.2.4). Since this ACK is retransmitted only by the UAC, it is effectively considered its own transaction. ..... And OpenSER is doing this - 200OK ACK is not part of the INVITE transaction. Now, about destroying the INVITE transaction after 200OK, I not sure if the RFC really states this. The RFC says the transaction is completed with the 200 OK, but not destroyed - this is more or less an implementation option, in my opinion.
