How to extend the number of rings before your phone goes to voicemail

This one is for my Aunty V, who had been finding that her iPhone was not ringing for long enough before switching through to voicemail. She was sick of running for the phone, only to find that she did not make it in time.

We fixed Aunty V's problem by extending the number of seconds that the phone rings, using a series of numbers and symbols on the phone's keypad.

Here are the instructions for each of the main Telcos:

• Telstra: **61*101** (number of seconds: 15, 20, 25 or 30) #.  Then press the call/send button.
• Optus: **61*321** (number of seconds: 15, 20, 25 or 30) #.  Then press the call/send button.
• Vodafone:  **61*61414121000** (number of seconds: 15, 20, 25 or 30) #.  Then press the call/send button.

Examples:  
   To extend Telstra rings to 30 seconds, enter         **61*101**30#  then the call/send button
   To extend Optus rings to 30 seconds,enter           **61*321**30#  then the call/send button
   To extend Vodafone rings to 30 seconds,  enter   **61*61414121000**30#  then the call/send button

If you have different mobile phone service provider to those listed, just try entering a Google search phrase like "extend the ring time for your mobile vodafone” (replacing 'vodafone' with the name of your mobile service provider) and find an answer to this question in the listed Google results.
