It is assumed that filters are created as sets of filtering rules, but it is also true that a filter as a created entity may not contain any rules. The application of such a filter to the service means for the system a complete ban on skipping any client traffic.
Adding one or more Filter rules to the filter will mean that the system will only allow traffic whose characteristics correspond to the established rules.
When adding a new rule to the filter, the Filter type and Settings are specified.
The system supports the following types of filters:
| Filter type | Description |
| SOURCE_MODIFIER_FILTER_TYPE | modifies the Source data, improving its quality and the format of the phone number |

| SOURCE_ALLOW_TEMPLATE_FILTER_TYPE | allows calls from sources matching the specified phone number pattern |
| DEST_ALLOW_TEMPLATE_FILTER_TYPE | allows calls to numbers that match the specified pattern |
| SOURCE_ALLOW_ZONE_FILTER_TYPE | allows calls from sources belonging to a certain zone |
| DEST_ALLOW_ZONE_FILTER_TYPE | allows calls to numbers belonging to a certain area |
| SOURCE_MODIFIER_BY_POOL_FILTER_TYPE | cyclically modifies the Source data from the specified pool |
| SOURCE_MODIFIER_BY_POOL_BY_ZONE_FILTER_TYPE | cyclically changes the source data from the pool depending on the zone of the B-number, optimizing the routing of calls by zones |
