Adding Routing Number Script

Applies to: Tmedia 2.9, 2.10, 3.0, 3.1

This article describes how to add a Routing Number script to any Routing scripts.

Requirements for this script

1. The routing number is included in the incoming call. For SIP in the Request-URI: INVITE sip:0038123456789;rn=8087321000;npdi=yes@192.168.101.160:5060

2. The routing table must use the called party number

3. The outgoing call will have: For SS7: Forward Call Indicators: Ported number translation indicator: number translated (Bit M) Called Party Number: 8087321000 Generic Number: [Not present]

4. The CDR needs to have the Called number set as the Routing Number

Then upload it in the system with these instructions: Import_Customized_Routing_Script_C

Setting up Routing Number Scripts

To set up a Filter, the main script needs to be modified. The main script can be either simple_routing.rb, simple_routing_sbc.rb, or any other script.

First, go to the routing script section of the Web portal

Gateway -> Routing scripts -> Example Scripts -> simple_routing_sbc.rb [Edit]

Four things need to be added. At the start of the script:

require 'r_n_cdr'

In the main class:

include RnCdr

before_filter :method => :RN_cdr

after_remap_filter :method => :Swap_back

The final script will look like this:

require 'base_routing'
require 'r_n_cdr'

class SimpleRouting < BaseRouting
  include RnCdr

  before_filter :method => :RN_cdr

  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

  after_remap_filter :method => :Swap_back
end

Update Text CDR Configuration

To have the Routing Number (RN) in the CDR logs, add these fields: Gateway -> Text CDR parameters -> CDR format (Start): ,RN='@{ScriptAttribute:RN}' Gateway -> Text CDR parameters -> CDR format (End): ,RN='@{ScriptAttribute:RN}' And replace the called fields: Gateway -> Text CDR parameters -> CDR format (Start): ,Called='@{ScriptAttribute:Called2}' Gateway -> Text CDR parameters -> CDR format (End): ,Called='@{ScriptAttribute:Called2}' See instructions here: Text_Call_Detail_Records

Configure LNP Settings

LNP settings need to be: profiles -> Outgoing calls LNP mode: Relay LNP Information profiles -> Incoming calls LNP mode: Forward LNP from incoming to outgoing call See instructions here: Modify_LNP_profile_D
