\
3- Add the following three lines to the script:

At the top of the page

```
require 'routesets_digit_analyzer'
```

Following your main class definition

```
include RoutesetsDigitAnalyzer
```

Add before filter in your main class

```
before_filter :method => :routesets_digit_analyzer, :trie_order => :called
```

\
4- Click 'Save'

### Example

```
require 'base_routing'
require 'routesets_digit_analyzer'                                                # <- Add this line here

class my_script < BaseRouting
  include RoutesetsDigitAnalyzer                                                  # <- Add this line here
  
  before_filter :method => :routesets_digit_analyzer, :trie_order => :called      # <- Add this line here
  route_match :call_field_name => :called
  route_match :call_field_name => :calling
  route_match :call_field_name => :nap
  route_remap :call_field_name => :called, :route_field_name => :remapped_called
  route_remap :call_field_name => :calling, :route_field_name => :remapped_calling
  route_remap :call_field_name => :nap, :route_field_name => :remapped_nap
end

@@routing = my_script.new

def init_routes( routes )
  @@routing.init routes
end

def route( call, nap_list )
  @@routing.route call, nap_list
end
```
