Having trouble with doing a InitialDPArgs request (CAMELv2)

[danievanzyl]

Hi, I'm not sure if I'm doing this incorrectly, but using the library, I am try to send the following HEX byte string that is ASN1 encoded.

307180016e83078313873881620385010a8a058493527008bb0580038090a39c01029f320836155030868778f0bf3417020100810791527088113046a309800736f50100f1026fbf35038301119f3605dad1c900079f3707915270881130469f38068170880804199f39080242100341402080

I was expecting that wireshark would be able to successfully decode the payload, but instead it failed
Expected,

But got the following,

Here is the code snippet I used to generate the tcapPayload...

	hexString := "307180016e83078313873881620385010a8a058493527008bb0580038090a39c01029f320836155030868778f0bf3417020100810791527088113046a309800736f50100f1026fbf35038301119f3605dad1c900079f3707915270881130469f38068170880804199f39080242100341402080"

	p, err := hex.DecodeString(hexString)
	if err != nil {
		fmt.Println("Error decoding hex string:", err)
		return
	}

	tcapPayload := tcap.NewBeginInvokeWithDialogue(
		uint32(*otid),     // OTID
		tcap.DialogueAsID, // DialogueType
		uint8(50),
		1, // ACN Version
		0, // Invoke Id
		0, // OpCode
		p, // Payload
	)

Am I missing a setting or flag to be set?

Any assistance will be greatly appreciated. I am fairly new to SCCP/TCAP/CAMELv2, so please excuse any ignorance or strange questions.

Many thanks,
Danie

sorry for leaving this for a long time… would you still like help? I think I can take a closer look this weekend.
