Signaling Security Filters

A signaling security filter is the assignment of a template to a vport for specific

direction (incoming/outgoing) with a specific priority. Up to 16 filters can be

created for a vport-direction coupling.

Filter priority – a number in the range 1..16 where 1 represents the highest priority

and 16 the lowest.

The filters priority defines the order of the filters, i.e. if filter A has a higher priority

then B, filter A will be checked prior to filter B when testing a call setup.

Direction – the direction specifies if the filter is assigned to calls incoming to the

vport or outgoing from the vport.

Filter’s state – A filter may be in one of two states: ON or OFF. When a filter is in the

OFF state it is ignored when testing a call setup and has no effect.
