Wireshark-dev: [Wireshark-dev] Unknown invokeData blob (GSM-MAP)

Hi all,

I'm tracing a GSM Map message which is not being fully decoded. I presume its an older MAP version 1 message while the ASN code is built on MAP version 2 or 3 and thus the packet type is depreciated. At least I couldnt find the specification in the 3GPP document for it anymore ony a reference to its name. Never the less, the system should be able to decode it and display, maybe with a warning.

Could anyone give a hint on how to solve this? Attached is a trace of such a invoke map operation 49.

I'm getting

Unknown invokeData blob

BER Error: This field lies beyond the end of the known sequence definition

Attachment: invoke49.cap
Description: Binary data
