A SIP Call-id is being presented three times

In a SIP/SDP SIP-Invite packet I can see call-id parameter three times. Twice in message header and once in message body. I can see that the binary part seems ok and it is just a matter of presentation. Is there a way to disable these duplicate call-id?

Currently not. It's supposed to be a feature where you can use the "extra" callids to filter out related packets.

Thank you, Anders for the prompt answer and attention. These aditional information is causing some confisuions when analyzing SIP invite pakects. Now I can see not only the three Call-ids but a fourth call-id from another leg of the call. So, in a invite packet I can see three call-id with the same value and a fourth call-id with the value of the previous leg. This is very confusing. Is there anything that I can do to avoid this?

To me it's a feature to find packets related to the same call as it goes through an IMS system. You can write code to make it an option. I think the extra call id are in square brackets indicating a generated item and are called associated call id so to me it's fairly clear what the usage is.

Yes, you are right they are in square brackets, but all of them has the same name "Call-ID" and not associated call-id, which in the end cause the confusion. For me it is clear also that it is just a extra info and not a real problem in the raw data. The problem begins when a need to share the traces and explain that my network is not sending duplicated info. Thank you again for your attention.
