Trying to make an application that can block/forward calls

[Bhargava]

Hi, I'm trying to write an application where I can manipulate the phone (blocking, forwarding, etc). I know there are probably apps that have this functionality, but I'm doing this for work. I've been searching for a long time for a way to deal with the phone on Android and I haven't seen anything that works. Any help is appreciated (even if you tell me it can't be done as that would take a load off me ). Thank you...

I could've used ITelephony in earlier versions

Google voice, blocks or forwards any calls whether they call your cell number or GV number.

I need code for doing that since I'm trying to implement it in an application.
