The default ring time on telstra is 15 seconds before diverting a call to MessageBank

• To extend the ring time, enter the following sequence on your mobile phone:
• **61*101** (number of seconds: 15, 20, 25 or 30) #
• Then press the call/send button.
• For example to set it to 30 seconds enter: **61*101**30#

Restore or remove original settings:

• Restore all three conditional call forwarding settings (Busy, No Answer, No Reply) to MessageBank, enter **004*101 #
• Remove all three conditional call forwarding settings (Busy, No Answer, No Reply) to MessageBank, enter ##004 #

Both of these actions will set the default ring time of 15 seconds.
