In NocTel Insight there will be several filters which present an (All) option. Selecting this when one or more valid options are selected will cause every valid option to be selected. Selecting (All) again when all valid options are already selected will cause every option to be de-selected. When making selections and de-selections you will invariably notice the visualization changing to match the filtered conditions occurring in real-time.generally need to hit Apply for each separate filter to make it to effect. This is intentional as it is undesirable to have NocTel Insight attempt to process individual filter selections when all selections intended may not have been made yet.
Lastly, a useful function unique to filters is they are searchable when the control is presented as a multi-select dropdown. When the dropdown is selected, before the first enumerated option is listed there will be a text field noting "Enter search text". This search field is case insensitive, but does not perform any auto-correct or guestimation of valid matches in the event of misspelling.
