\
2- Edit your main script

<br>

\
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
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/configuration-details/configuration-by-web-portal-category/call-routing/adding-label-routing-to-a-routing-script.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
