How do I change the length of time before a call goes to voicemail?
You can change how long your mobile is set to ring before going to voicemail from 5 to 30 seconds, in 5-second intervals. It's set to 15 seconds as standard.
To change the time:
Dial **61*121*10*
Then, before pressing call, enter the number of seconds you’d like your phone to ring for, followed by #
Press Call
A confirmation message will pop up on your screen with your new ring time
For example, setting it to 25 seconds would look like this: **61*121*10*25#.
This applies for both voicemail and Visual Voicemail.
