Ok guys. I have offered to write an article on a technique that i often
have a lot a fun with, and it come up as an interest to others. The service
i am talking about is call fowarding, and more specifically, we will be using
the foward before ringing function. I have also included some telstra test
numbers, which can be really useful as redirection targets.

Theory:

Well the theory of this technique, is simply phone redirection. The excellent
thing is, with home phones, you can redirect to telstra error messages.
All those 12722 numbers can be used to create some really weird mesages
when people are ringing.

Technique:

1. Okay, now the phun part. Firstly, take your list(appended on to the bottom of
this file, credits to Decimalz).

2. Select a number that you wish to redirect to. I myself, am fond of the 127224*
range.

3. Enter *21#

4. Ring your home number, and hear the message you selected.

5. To turn off enter #21#

List of Forwarding functions:

*21# - Immediate forward to target
*61# - Forward on no answer

*61*# Forward to target on no answer, after time delay.

*24# - Forward on busy tone.

With the above technique, and below list(any number can be used, not just
this list). This technique is really easy to do, and also introduces some basic
principles of call redirection. It is also so very amusing, especially when you
know someone will call and you dont want to talk. Its amazing how often telstra
disconnects my line when i know they will ring.
