Programmatic obfuscation

Throughout this guide, we will adopt the the

example above, where telephone calls that contain spoken credit card information need to be masked out by an audible tone, but only during those parts of the call when the card details are being spoken, leaving intact the rest of the call audio.

In this scenario, we will assume that agents (employees that make or receive telephone calls) utilise an in-house or third-party data entry system into which credit card detailed are entered using a computer.

How it works

Considering TIM Plus (in conjunction with one or more Magic boxes) records the call audio at strategic boundaries in your telecom infrastructure - usually your organisation's telephone lines, rather than each user's telephone handset - some reconciliation is normally required between those boundaries and the actual agent that handled the call.

...

A single telephone call can contain more than one obfuscation and the number of signals required is always twice the amount of obfuscations in a call.

Assumptions

This guide assumes the following statements are true:

• You have a licensed copy of TIM Plus that includes voice recording
• Your installation is at least version 3.0.0.55
  

Common solutions

Taking the example of masking out some digits of a phone call when a credit card number is being quoted, most solution providers modify the data entry system that an agent uses.

Implementation

HTTP request

To send a start or stop signal, a simple

request must be sent to the TIM Plus web server.

The response status code will indicate success or failure.

Request format

The request should be a
