IMSI value incorrectly decoded in RANAP prot./id-CommonID procedure. See
example:

            commonID

                            id: id-PermanentNAS-UE-ID (23)
                            criticality: ignore (1)
                            id-PermanentNAS-UE-ID: iMSI (0)
                                iMSI: 32010151006067F2


It should be 231010150006762 instead of 32010151006067F2  (byte order reversed)
If needed I can send binary trace file.
Thank you.
