Re: How to change the ring time on my phone when connected to NBN?

This works as I did it long ago:-

Extend Ring Time for Messagebank/Telstra Home Messages 101. Step 2: Enter the number of seconds you wish the phone to ring before a call is diverted (between 5 and 60 seconds). To extend the ring timesimply enter * * 61 * 1 0 1 * * (number of seconds: 15, 20, 25 or 30) # and press SEND or CALL.
