Hi,

What version are you using?

This may be due to a problem with returnResultNotLast (7) solved in the upcoming release 0.99.6 you can

try the pre-release from http://www.wireshark.org/download/prerelease/wireshark-setup-0.99.6pre1.exe  "BER: Dissector for OID:1.2.826.0.1249.58.1.0 not implemented. Is a private

extension container which can’t be dissected without knowing the asn1 notation of the encoded data.

Regards

Anders

Ämne: [Wireshark-users] GSM MAP SendRoutingInfo not decoded correctly?

 

Hi all,

For those experienced in GSM MAP, you may know when GMSC send out a "sendRoutingInfo" to HLR to query a msisdn, it will expect to receive imsi of the msisdn. However I found my trace file does not decode the "sendRoutingInfoRes" correctly, it seems to be cut as seen in below extracted record, the first Frame has empty "GSM Mobile Application" part.

and acturally I can see in the "Transaction Capabilities Application Part" of first Frame, "Data: 24004102320279F7" indicate the imsi, however it does not show correctly in MAP part.

If you tried to use wireshark to decode the trace file I attached, you will see "GSM MA Unknow GSM-MAP PDU". And the second Frame also indicate "BER: Dissector for OID:1.2.826.0.1249.58.1.0 not implemented. Contact Wireshark developers if you want this supported".

 

Any hint is appreciated!

Joyce
