Maintaining Synchronization by Auditing Terminations

You can use the AuditValue command in H.248 messages to maintain synchronization between the BGF and the gateway controller. The AuditValue command requests the current values of a descriptor or of a single property, event, signal, or statistic associated with terminations and contexts. You can include selection criteria in the AuditValue command to filter the returned values.

The software supports the following characters for audit selection criteria:

• equal to (=)
• not equal to (#)
• less than (<)
• greater than (>)

Using AND/OR Logic with Audit Commands

You can include multiple criteria with an AND or an OR logic operation (ANDLgc, ORLgc) to indicate how the selection criteria are interpreted. If you do not include a logic operation, AND logic operation is applied.

Example: Audit Section Filter with AND Logic

Transaction = 201 {
    Context = * {
        ContextAudit {
            ANDLgc
        },
        AuditValue = * {
            Audit {
                Media {
                    LocalControl { 
                        gm/saf=on,
                        gm/spr<4075,
                    }
                }
            }
        }
    }
}

Transaction = 202 {
    Context = * {
        ContextAudit {
            ORLgc
        },
        AuditValue = * {
            Audit {
                Media {
                    LocalControl {
                        gm/spf=on,
                        gm/sam=10.10.0.3,
                    }
                }
            }
        }
    }
}
