Yes there is. I've been frustrated with Telemarkers always calling with their robocall systems. You can't request to be taken off the list because it's a robocall number. Well, here are a couple of steps I took.
1. Find a disconnect number you can use or some other "interesting" number you can forward them to.
2. I enabled the "foward when busy" option on my iPhone by doing the following:
Select the calling option on your iphone, the green icon with the phone on it. Dial the following,
*67phonenumber# then press call. The phone number is the "interesting" number you chose to use.
3. When a call comes in you want to "divert" over to the "intersting" number you selected, simply press the lock button or decline option on your phone if it's unlocked at the time of the call.
I set mine to a disconnected number. So when I receive calls from "unknown" numbers, I simply divert them.
When a number is displayed and turns out to be a telemarketer, I add the number to my telemarketer contact. That contact's ringer is set to silent so, I don't have to hear the phone ring. All this is free.
