how do i alter number of rings before voicemail cuts in

@thomas+sweetman 

To change it, dial: **61*759*11*XX#

Replace the XX's with the amount of time you want the phone to ring for, before it transfers calls to voicemail. The maximum time you can set it to is 30 seconds.

E.g. **61*759*11*25#

That would change it to 25 seconds.

Does not work. Connection problem or invalid mailbox code

Try this, taken from here 

1.  Enter **61*0 7 4 8 8 2 2 2 0 0 0 *11* (without spaces)
2. Enter a time in seconds
3. Press #
4. Press call

For example: if you want your phone to ring for 30 seconds before it diverts to voicemail:

1. Enter **61*0 7 4 8 8 2 2 2 0 0 0 *11*30# (without spaces)
2. Press call
