About Calling Number Display
Calling Number Display (CND) can help you identify who is calling by displaying the caller's phone number. It can also store the date and the time of the call, as well as the phone numbers of people who hang up without leaving a message.
You will need a CND compatible phone or CND unit in order to use this feature. The CND Rental Phone T1000C is available to rent from Telstra.
Pricing
CND is $6.00 per month.
This feature can be included in the HomeLine® Features Package.
Availability
CND is available on tone phones in most areas throughout Australia. However, you will need to purchase or rent a CND compatible phone or attachment for your existing phone to display caller details.
Disclosure of your Calling Line Identification
If you have call blocking or line blocking enabled on your phone line, or you have a Silent Line, your Calling Line Identification (CLI) will generally not be disclosed to third parties.
However there are some circumstances in which your CLI will always be disclosed. You cannot block CLI on calls made by you or someone else on your phone line:
- to the emergency call service (000)
- on internet dial-up calls made to an Internet Service Provider (ISP) that uses a Telstra ISDN service or an 0198307 or 0198308 access number, but only where the ISP uses the CLI for fraud prevention, billing, call management or credit control
- when you or someone else sends a text message or replies to a Talking Text message from your Basic Telephone Service - in accordance with worldwide standards for SMS, all messages including reply messages will display the telephone number of the sender when you or someone else uses another carriage service provider by using a network override code.

Anything else I need to know?
Calling Number Display capable telephones are designed to mute the receiver for 1-2 seconds while the details of the caller's number are sent to the telephone. This may cause a brief interruption to the conversation. Occasionally, some telephones may mistakenly respond to a caller's voice or external noise and cause a false muting of the telephone receiver.
