hello !!

I am a student in France , I am in internship for 4mois;
my 1st mission is to develop a plugin that decodes a Protocol used in the company.
I have installed all the development environment of wireshark,
I have studied how to make the plugin!(no Pb) .


 After I started studying the Protocol to decode .it’s specific protocol in UUI(user_user information element )message

Let me explain briefly the Protocol

* Networking information conveyed in IUU Q931 (User-User information) and the user-user information element is codeded as shown by this protocol:

 

0X7E

 

Octet 1

Length of user –user info

 

Octet 2

Protocol discriminator:

0x00 :User Specific Protocol

 

    Octet 3

 

 

User information

0xFE = PBX protocol identifier

 

     Octet 4

 

                                                                User information .......

                                                                    …..

    Octet5

      ……

 

 

 

 

                                                User –user information element

 

 

 These are the problems I found:
I can not started because I do not know how to distinguish this part of the package:
Thank you for any idea
