Hi,

 

I just tried it with several traces I have. First, great job, the decoding looks really nice already!

 

Here are my results:

1- All tests

    1.1- In colinfo, the message type is not indicated (begin, continue, end, ...). This would be nice.

    1.2- ITU/ANSI auto-detection works nicely. Still have to set the standard in MTP3 preferences.

2- TCAP ITU - Camel

    Works nicely.

3- TCAP ANSI

    3.1 An ANSI MAP trace doesn't display a MAP tree on the GUI. MAP protocol goes directly in the component portion. I don't know if this is intended, but it's a little bit disturbing given that Ethereal always create a tree for a protocol layer. An ITU MAP works OK.

        -> see tcap_1.jpg

4- TCAP ITU - unknown upper protocol

    This time, no upper protocol is triggered. So TCAP dissector is on its own.

    4.1- For a Camel trace (Camel dissector de-activated), I get BER errors and nothing is decoded. The expected behavior would be to have parameter types, length and value displayed (previous TCAP dissector was doing that)

        components:
            Item: invoke (1)
                invoke
                    invokeID: 1
                    BER Error: This field lies beyond the end of the known sequence definition.
                    BER Error: This field lies beyond the end of the known sequence definition.
            Item: invoke (1)
                invoke
                    invokeID: 2
                    BER Error: This field lies beyond the end of the known sequence definition.

 

I can provide the captures with a direct email.

 

Regards,

Olivier.
