Overview

TIM Enterprise Plus offers the ability to obfuscate (mask out) one or more sections of the audio of a telephone call with an audible tone, preventing the listener from hearing the original speech.

...

In this scenario, we'll 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

Because TIM Enterprise 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.

By default, this reconcilliation occurs automatically by TIM EnterprisePlus, which is how the agent-centric calls that you see in call reports are able to be associated (matched) with each call as seen from the point of view of a telephone line, which delivers calls to many agents.

During obfuscation, it is necessary that a user or device sends at least two signals to TIM EnterprisePlus. Together, these two signals allow TIM Enterprise Plus to mask out the audio between the two points in time that each signal was received.

...

At the point in time during an agent's call when obfuscation is necessary, e.g. "Can I have your CVV number please?" is spoken by the agent, a signal is sent by the agent to TIM EnterprisePlus, which records the event along with the exact time it was sent.

Similarly, when the sensitive part of the call has completed, a further signal is sent by the agent to TIM EnterprisePlus, which records that event too.

...

  • You have a licensed copy of TIM Enterprise Plus that includes voice recording
  • Your installation is at least version 3.0.0.55
  • You have one or more Magic Boxes installed, each with their governing RTA Service

...

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 

Referencemacro
LabelHTTP GET
request must be sent to the TIM Enterprise Plus web server.

Every request to the web server requires authentication, so ensure that the relevant HTTP authentication headers are sent with your request and that the username and password combination match an existing web user object in the Directory.

ParameterDescription
200The signal was received and stored successfully
400The request was not acceptable for one of the following reasons:
  • An invalid type parameter was specified. The type parameter is specific to the category specified by the cat parameter. Further, the type value (e.g. 0x01) can be used in multiple categories
  • The objid was missing. Specify the ID of the object you want the signal to relate to
  • The cat and type parameters - category and signal type, respectively - must be specified and cannot be zero
  • The version of TIM Enterprise Plus you are running does not understand the signal.js script
404The object specified by the combination of the objtype and objid parameters - and optionally the key parameter - could not be found
