There has to be a way to block this call centers from india. I got 4 calls from them today and each time they asked for someone different. They where all blocked numbers.

Most phone companies have a service for that. I think it's called Privacy Manager or something like that. Every phone company has a name for it. I used to have it when I lived up north and when someone calls blocked they get a recording requesting them to call back with their number unblocked or leave a message. On your end, the phone does'nt even ring.

I have call block for people calling with block numbers, but since they send data to caller id that says unknown, they are able to get past that block.

I do believe there is another service as you mention that is implemented by the phone company. I will give them a call and weigh my options, this is aggravating.
