Yes, when conversation is set up from say the SDP dissector for the
upcoming rtp flow we will not know on which wire it will appear.

So perhaps the reassembly code should take into account the conversation
ID (with conversations not taking the wire ID into account) *and* possibly
also the wire ID, with a preference to indicate whether to include the wire
ID or not (set the preference when there's routing between wires going on,
don't set it if, say, wires are being bundled together for greater
bandwidth, or different VLANs are being used for upstream and downstream
traffic, or...).

Yes or possibly ignore the higher layer and just say someting like
[duplicate on transport ] as seeing multiple application messages my
confuse people. That should perhaps be a preference too.
