  • Ticket #1391

    • Property Summary changed from Missing transaction/cseq check for incoming ACK in an INVITE session (thanks Ilya Kalinin for the report) to Missing CSeq check for incoming ACK in an INVITE session (thanks Ilya Kalinin for the report)
  • Ticket #1391 – Description

    initial v2  
    1 Case scenario: 
     1CSeq is not checked for incoming ACK request. This may cause ACK retransmission for previous INVITE transaction to wrongly be processed. 
     2 
     3Sample scenario: 
    24 1. Receiving normal INVITE with SDP, processed normally until reaching confirmed state, let's call this TSX 1. 
    35 2. Receiving re-INVITE without SDP, responded 200 OK with SDP, and waiting for an ACK with SDP, let's call this TSX 2.
