Hello, we had a discussion about handling of retransmitted INVITE after the UAS was sending a 200 OK but did not received an ACK. The transaction layer will open a new INVITE server transaction because the layer has no information about the first initial INVITE. In the UAS core it is possible to recognizing the INVITE as a retransmission. But what should the UAS core do? I read section 13 and 17 but I found nothing.
Another discussion was going about that a retransmitted INVITE could be slower as an ACK because the ACK is send direct. Our client will complained about the CSeq number that is too low and the trouble is two INVITE (initial + retransmitted) which are the same but two responses (200 and 500). What can I do? Thank you for your help!
