The Telecommunications (Do Not Call Register) (Telemarketing and Research Calls) Industry Standard 2007 has been amended by the Telemarketing and Research Calls Industry Standard Variation 2011 (No. 1) to regulate calls that involve a recorded or synthetic voice and to require certain information to be provided when making a telemarketing or research call, including details of where the person calling obtained the Australian number called.

When a caller makes, or causes to be made, a telemarketing call involving recorded or synthetic voices, the caller must ensure that a mechanism to enable the call recipient to request information is provided during the call.

A caller must ensure that calling line identification is enabled at the time that the caller makes or attempts to make a call, or causes a call to be made or attempted to be made. A caller must not block the transmission of the calling line identification to any calling number display or any calling name display of a call recipient who receives the call.

Callers must make reasonable efforts to ensure that when calls are made, the number which is transmitted to the calling number display of the receiver terminals is a telephone number which is suitable for return telephone contact by a call recipient. The call recipient may be advised of the facility to request such information by pressing a button to talk to an operator or to obtain further details about the call, the caller and/or the entity that is causing the call to be made.
