The f=Filters filter options set in the dialog window override the command line option settings. If no new filter is entered, the current filter will remain active. To clear all filters, type e or erase in the New Filter field. The following is an example of the available filters:

│Display Filter Usage:
  -u <URI|NUMBER>  Filter calls that contain <URI|NUMBER> in
                   the 'From' or 'To' field.
  -i <IP>          Filter messages from/to <IP> address.
  -port <PORT>     Filter messages from/to <PORT>.
