Seems you also need a "Business Line Select plan" with Telatra to qualify.
I assume that's a business PSTN service. (I'm not familiar with Telstra's
terminology and pricing anymore. When I was last with them, the AMPS
network was still running and you had a choice of Flexiplan 20, Standard,
80, 130, and 240.)
