<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>

<div>To detect the "image" session in the SDP, you are
thinking the same way that I am. The problem I see is
how to actually reject the re-INVITE. 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. That sounds to me like a recipe for problems in
future in-dialog transactions (like BYE).</div>

<div>Maybe stream_exists(regexp) in sipmsgops module

<div>Is there anything I can do at the
proxy level to prevent a dialog from
reinviting to to T.38? I think I
could detect the T.38 attributes
easily enough and respond with a 488,
although I'm concerned the CSeq values
would be out of sequence for the next
transaction that did make it through
the proxy to the far end. That could
cause a problem, no?</div>
<div><br>
</div>
<div>Is this something that requires a
B2BUA? Is it possible from within the
OpenSIPS B2B modules to do SDP
inspection of any sort?</div>
