Screen your calls with Call Number Display on your home phone
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.
