Re: How to modify existing RTP conversation?

Hi,

  did I made wrong code analysis and root cause is somewhere else?

I would like to know where this is done:

 I analysed the code and found that for #1 is created "full"
conversation (full = SRC_IP:SRC_PORT <-> DST_IP:DST_PORT) with UDP as
protocol.

because that sounds questionable. 

packet_udp.c: dissect() calls find_or_create_conversation(pinfo) for
every packet. When packet is new (#1 in my example), it creates new full
conversation just for UDP layer.
Conversation is created as full/bidirectional, I checked it with enabled
DEBUG_CONVERSATION.

                                                Sincerely yours,

                                                        Jirka Novak
