        <br>
        This is a false problem - you can simply decline the re-INVITE
        without breaking anything - each side has its own cseq number,
        and they are independently increased when a party is generating
        a new requests.<br>
        <br>
        So, just decline it and that's it !<br>
        <br>
        Regards,<br>
      </tt>

              <div>To detect the "image" session in the SDP, you are
                thinking the same way that I am. &nbsp;The problem I see is
                how to actually reject the re-INVITE. &nbsp;If I were to do
                something like a sl_send_reply("488", "Not Acceptable
                Here"), that would work in the moment, but the CSeq
                values would be increased by one on side compared to the
                other. &nbsp;That sounds to me like a recipe for problems in
                future in-dialog transactions (like BYE).</div>
