Product: Wireshark
Version: 0.99.2
Platform: PC
OS/Version: Linux
Status: NEW
Severity: Normal
Priority: Medium
Component: Wireshark
AssignedTo: wireshark-bugs@xxxxxxxxxxxxx

It seems to be invalid byte order in parsing point codes in
epan/dissectors/packet-mtp3.c:
#define ANSI_NETWORK_MASK 0x0000FF
#define ANSI_CLUSTER_MASK 0x00FF00
#define ANSI_MEMBER_MASK 0xFF0000
Should be:
#define ANSI_NETWORK_MASK 0xFF0000
#define ANSI_CLUSTER_MASK 0x00FF00
#define ANSI_MEMBER_MASK 0x0000FF
