Rules configuration
To create, edit and delete rules, the buttons "Add", "Edit" and "Delete" are used. The green arrows next to
the edit buttons allow moving the highlighted entries in the table, adjusting the order of the rules created.
SBC Configuration –> Rule set –> "Edit"
– Name — an arbitrary name for
identification, convenient for the operator;
– Action — the action to be taken on messages
that are subject to the conditions of the rule:
– Reject — the message will be
rejected;
– Send to destination — the message
will be sent to one of the
destinations;
– Send to trunk — the message will be
sent to one of the trunks;
– SIP Destination/SBC Trunk — a field for
selecting a destination or a trunk, appears
when selecting an action other than Reject;
– Drop Diversion header — when enabled, the
Diversion field will not be transmitted

– Work time interval — the time interval during which the rule will be enabled. Outside this interval, the rule
will not work. The setting format is a time range written as "HH:MM-HH:MM".
