Phone functionality

From the rotary dial you can do the following:

[1] Look at phone book entries
[2] See Nokia battery remaining
[3] Check 'timeup' of the RPi
[4] Program the phone book

All of this is done on the Raspberry Pi, the only thing the phone is used for is sending AT commands to to make calls, answer calls, end calls or check battery.

The phone book is stored in a properties file that is accessed from the main phone Python script.
To program it dial 4 to put it in program mode then enter the phone number to store, prefixed with the position you'd like it stored at.

e.g. 4123 will add the number 123 at position 4 in the phone book.

Dial 4

...enter index then number

Dial 1 to look at the phone book entries...

 To dial a phone book entry it's 1x, where x is the entry position of the number..
