Dialing *67 before the number will prevent your number from showing up on caller ID or being retrieved via *69. On a Cell Phone you need to dial #31# before you number *67 wont work on a cell phone(not in Canada anyways) This is what works for me when I need to block cell numbers http://howtofixstuff.blogspot.com/2012/03/how-to-block-numbers-on-cell-phone.html
From your cell phone directly, the number is typically 123. T-Mobile phones often have this programmed in already for speed dial on number 1. Press and hold the 1 button until it starts dialing and you'll typically be taken to voicemail automatically.
