Block wrong short numbers with Localization

To block ALL short numbers (length [1-8]) you need to:

1. Create Empty LCR
2. In Localization add such Rule:

NOTE: Such rule will route calls to empty LCR where they will be dropped.

If you want to allow some short numbers to pass, you need to create more granular rules to handle your situation.

This example is very strict and is only for demo purposes to illustrate the principle.

Make sure you understand Number Manipulation to proceed with Rules for your case.
