Inteligent CLI Validation

Сontrol your surcharges

Block invalid CLIs by rejecting non-conforming calls.

Helping Operators Providers Telcos to conform with UK Ofcom rules

Also for users operating basic and open-source equipment with limited control over CLI manipulation and presentation.

Why

New Ofcom CLI Rules

Ofcom CLI rules can lead to surcharges on calls terminating in the UK. As part of their attempt to reduce spam and telecoms fraud from 1st August 2021, regulator Ofcom introduced new origin-based surcharges for internationally originated calls to UK geographic (starting 01/08/2021) or mobile numbers (starting 01/09/2021).

Surcharges have to be applied where a CLI is missing, corrupt, malformed or unknown. Pre-defined charge bands apply based on destination (UK mobile/fixed) and vary by source country code and can be as high as £2 per minute.

What

CLI Validation Service stops these calls from happening

By using Netaxis CLI Validation, Service Providers in the UK can prevent calls that would attract a surcharge from being completed. The service rejects calls with missing, corrupt, malformed or unknown CLIs and, using a tabular lookup, applies the relevant charge band for allowable calls. Block invalid CLIs!

HOW

How we do it

For a UK based CLI, it will verify that it is valid by referencing Ofcom assigned official number ranges. A failure in this verification will cause the call to be rejected (configurable). For a non-UK based CLI, it will match the CLI against a list of surcharge bands, each of which has a different surcharge price per minute, per destination (UK geo vs UK mob). You can define on a customer by customer basis allowable CLI bands.
