Well, i had my apprehensions on how successful this is going to be. But going by my personal experiences, it has been quite a relief. From an average of atleast 10-15 marketing calls a week, the number has come down to almost zero. People are still finding workarounds as i get SMSs with the sender phone number hidden, but that is something that i can live with. A far cry from the earlier situation when you get a call in the middle of some important work and you are in a quadary whether to pick or not.
