Examine the MODULE_NAME and the IMAGE_NAME. The information these provide, like wxvault.dll or CiscoJabber.exe, indicate what application caused the crash. In this case, the crash occurred because of issues with the Cisco Jabber.exe application and not with the user?s machine. A Google search shows that wxvault.dll is related to the DELL Embassy Trust Suite.
Send the Cisco Jabber Problem Report to the Cisco Technical Assistance Center in order to determine if the crash dump is related to a known defect that has a possible workaround.
