[SR-Users] dialog.dlg_filter_mode has ambiguous definition with double negation

Hello, https://www.kamailio.org/docs/modules/devel/modules/dialog#dialog.p.dlg_fil… says for dialog.dlg_filter_mode (int) Set dialog fitering mode, which can specify what dialogs are processed. Its value can be a combination (the sum) of following flags: 1 - do not send keepalives and do not execute timeout function if dialog is not local (if the associated bind address is not a local socket). Default value is “0”. As you can see, the definition of 1 is a double negation and there is no definition for 0. What means 0: - do not send keepalives and do not execute timeout function if dialog is local - send keepalives and execute timeout function if dialog is not local - send keepalives and execute timeout function if dialog is local
