Hi Anders,

 

we found the problem with frame #2.

 

The conversation with permission is for continuing the dialog

between the two users.

 

The Transaction ID part of the Conversation Portion contains TWO

transaction identifiers.

 

You'll notice the Transaction ID length is 8 and there are two IDs or 4 octets each:

Originating Transaction ID

Responding Transaction ID

 

So in frame #2

 

Otid = 0x0000000e

Rtid = 0x00000027

 

with the Rtid corresponding to the invoke transaction ID.

 

Thanks

Hi,

Frame 1:

BER Error: Unknown field in SET class:CONTEXT(2) tag:390

I don’t have a protocol reference where MCID is included in facilitiesDirective2.

 

Frame 2:

I think the problem is that the identifier:

identifier: 0000000E00000027

is not the same as in the INVOKE (Frame 1)

identifier: 00000027 and WS can’t match the response.

 

Frame 3:

I’ll check in a fix.

 

Best regards

Anders

Hello,

 

I'm having some issues with the attached capture file.

 

This capture contains ITU MTP3.

 

There are a couple of issues:

 

Frame 2:

 

ANSI TCAP problem, conversationWithPerm isn't supported ?

 

Frame 3:

 

I think this is an ANSI MAP dissector problem.  That last line in the packet details window says "Unknown invokeData blob".
