I have Tasker for Android but I don't know enough about it to be able to implement this.
I'd like this to occur when I am connected to a specific wireless network:
If someone phones who isn't in my contact list, reject the call immediately (straight to voicemail).
If they call again within a certain amount of time (say, 30 seconds) allow the call to come through.
Frankly, I can't even get the first one working. I know it's possible. The time thing is a kind of added bonus
