ID: 5618 Title: skype.sip_stack: Fixed "missing key" error which caused a check crash Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i3 Above error was a result of different key notations for the same object, eg. in "skype.sip_stack" we got - "SIP - Incoming Responses Dropped /Sec" and - "SIP - Incoming Responses Dropped/sec" Now we normalize these keys by ignoring upper/lower case and spaces.
