Telstra CLI IVR Prompts

2 min. readlast update: 09.02.2025

As part of Telstra's response to new telecommunications industry regulations around reducing scam calls, Telstra are now prompting users to respond with a key press when they receive a call from Crazytel where the phone number presented is one that resides on Telstra's network. In some cases where the receiving party is not with Telstra, the calls may fail to connect.

As a practical example, if you have a service from Telstra with the phone number 0712345678, and you have added this phone number to your custom Caller ID for your Crazytel service, calls to other Telstra numbers trying to present 0712345678 will prompt you to press a key before the call is connected. If the correct key is not entered, the call will not connect.

This applies to both Telstra mobile numbers and Telstra landlines.

To ensure your service is not impacted by these changes, there are two options available to you:

Port Your Telstra Number to Crazytel

Change Your Caller ID

The ACMA and Communications Alliance introduced additional regulations (Reducing Scam Calls) recently in an effort to identify and block scam calls. You can find the code at the Communications Alliance website

Telstra's approach is designed to combat 'spoofed numbers', where a scammer sets their Caller ID to a number different to their own in an attempt to convince potential victims to answer their calls, and of their legitimacy.
